Creating Sheet Metal Flat Pattern

It is necessary to make the transition from a round tube to a square of sheet metal. Let us consider the principle of constructing such scans from sheet metal. In order to get a sweep of it you need to build it using the tool "Element by the bend cross-sections". It is located in the Sheet Metal toolbar, in the Insert menu - Sheet Metal, on the Sheet Metal tab, or you can take it to the right place when setting up the Solidworks interface.

Insert features "Lofted Bends" -LeninSW

"Lofted Bends..." 

The construction scheme is as follows:

We construct a sketch of a circular non-closed section, the gap is necessary to obtain a sweep. The gap must be dimensioned (generally a fully defined sketch reduces the probability of error), you can make 1mm or less.
Solidworks - Эскиз круглого незамкнутого сечения

Sketch of a circular open section

We create a plane on which the profile of the second section will be located and on it we draw an open quadratic profile, with a gap. Gaps can be linked either by an equation or by using separated values (more conveniently).
It is necessary to round the corners of the square section, otherwise Solidworks will give an error.
Solidworks - Эскиз квадратного незамкнутого сечения

Sketch of square open section

After that using the Solidworks tool "Element for the bend cross sections", create a transition from the sheet metal, select the first profile, then the second one and specify the thickness of the metal. Take into account the direction of the thickness, because if the direction is inside, the thickness should be less than the radius of the fillets. The direction must also be considered based on the specified dimensions, a fixed internal or external dimension is needed. Confirm the execution of the command and get a transition from sheet metal.
Solidworks - Переход из листового металла

The resulting transition from sheet metal

There is an interesting point, there are no sweeps in the configurations. You can create it manually and highlight the sweep element in the build tree.
Solidworks - Развертка перехода

Flat Pattern

But when creating a drawing, this configuration of "SM-FLAT-PATTERN" containing the part in the expanded state is created automatically.

Now let's proceed to export the sweep to the dxf format, for the subsequent cutting on plasma cutting, laser or waterjet. To avoid errors with scaling, I recommend exporting directly from the part. To do this, activate the configuration with a scan, click on the flat surface with the right button and select "Export to DXF / DWG", select the save location and file format. In the same window, you can configure the export options in dxf / dwg, for this click the "Options" button. From the settings I recommend turning on "Export all splines as polylines" and "Enable connection", the necessary gap clearance is selected by yourself.
Solidworks- Настройка экспорта в dxf/dwg

Setting up export to dxf / dwg

After the export is confirmed, the "DXF / DWG Clear" window opens, in this window you can delete unnecessary holes or other elements.
Solidworks - Очистка dxf


 If necessary, you can undo the changes. After cleaning, click "OK" and the dwg/dxf  file is created in the location you specified.

Just sweep can be done without activating the flat state. To do this, select the unfoldable surface and save it as dxf. Solidworks add the "Sweep" before the name of the saved part. Further as in the previous case.

The other way is even simpler, right-click on the Sweep in the design tree and select "Export to DXF / DWG", further as described above.

And the easiest way, just save the part as dxf / dwg, the rest as in the previous cases.

And finally, the most complex and most (as it turned out) common option: saving from the drawing.
The bottom line is simple, you insert a sweep in the drawing sheet and save it in dxf / dwg. In addition to more actions, this option carries a very unpleasant feature: distortion of the scan scale. If the scale of the sheet coincides with the scale of the drawing view, there will be no scale distortion. In other cases, there are different options and this is the topic of a separate article. Therefore, I recommend exporting from the model, there will be no problems with scaling.

Isolating components in Solidworks

Solidworks has an excellent feature for isolating parts and assemblies designed to simplify the modeling and design of drawings. Many do not know or do not use this functionality. On the video you can see the use of isolation in Solidoworks.

Solidworks Help

The Isolate command sets all components except the selected ones to be hidden, transparent, or wireframe, enabling you to focus on the selected components.

You can isolate parts or subassemblies, making it easier to edit them in the context of the assembly. You can also isolate components that share a mate.

You can use the Isolate popup toolbar to change the visibility of the hidden components to Wireframe, Transparent, or Hidden. The transparency usually used when editing a component in the context of an assembly is not used when Isolate is active.

Before you exit Isolate, you can save the display characteristics to a new display state, which you can access from the ConfigurationManager. If you do not save, the display returns to its original state without any permanent changes.
When you select Hidden, you can match the FeatureManager design tree to the graphics area by selecting Filter Hidden/Suppressed Components in Filter .

To isolate components that share a mate, right-click the mate in the FeatureManager design tree and click Isolate.

How select hidden items

Often there is a need to make the mating of parts, with a surface or edge that is not visible. The function "Isolate" is not always convenient to apply. Fortunately, it is possible to specify the required element for pairing, even if it is not visible.

Solidworks Help.
Selects entities that are hidden by other entities.
To select hidden items:
  1. In a part or assembly document, right-click the model in the graphics area and choose Select Other menu_Select_Other.gif.
    • The pointer changes to pointer_Select_Other.gif and a box appears with a list of entities (faces, edges, subassemblies, etc.) that lie beneath the pointer, in the order in which they are encountered. An icon displays the type of entity (face, edge, etc.).
    • Hover the pointer over items in the list to highlight them in the graphics area.
    • To scroll through the list, press Tab or roll the middle mouse button.
    • You can right-click on the model to hide faces, revealing other hidden faces and edges.
  2. Click in the list or the graphics area to select an entity.

If the first time in the list is not the desired item, cancel and select the area closest to the desired item.

Using a Multiple Unit System in SOLIDWORKS

Regardless of which measurement system we draw, Solidworks allows calculations in both the metric and Imperial systems. To do this, simply add a unit of measure after the value. For example, in the metric systems by entering 100ft, we get a size of 30480 mm. Similarly with the Imperial and US customary measurement systems, by entering 30480 mm, we get the equivalent in feet or inches . Also in metric systems, you can just write 25 cm and this will translate into 250 mm.

Available values

  • m - metre (1000 mm)
  • cm - centimetre (100 mm)
  • um - micrometre (0,001 mm)
  • nm - nanometre (0,000001 mm)
  • A - angstrom (0,0000001 mm)
  • ft - foot (304,8 mm)
  • in - inch (25,4 mm)
  • mil - mil (0,0254 mm)

Here is a quick video demonstrating this functionality:

SmartMates in Solidworks

In Solidworks, you can simplify the interfacing of components. Press and hold "Alt" to move the mouse pointer to the desired surface, press the left mouse button and drag to the second surface for the auto-conjugation. A pane will appear with the default interface already selected for these surfaces. Those. if the surface is flat, then the automatic interface is a coincidence, if the surface is cylindrical, then the automatic interface is concentric. There are other options for automatic pairing

(SmartMates Procedures)
Desired Mate Action
What to Do
Mate two components already in the assembly. Press Alt and drag one component onto another.
Mate a new component while adding it to the assembly.Drag a part from another window onto another part in the assembly.

  • From a part file: Select an entity and drag.
  • From an assembly file: Hold down Shift, then select an entity and drag.
Fully mate a commonly-used component while inserting it in the assembly.Drag a part with mate references from Windows Explorer or the Design Library into the assembly. This method can fully mate a new component, but you must set up mate references beforehand.

Types of SmartMates
The mates added by the SolidWorks application depend on the situation.
    In most cases, the application creates one mate. The type of SmartMate created depends on the geometry used to drag the component, and the type of geometry onto which you drop the component.
    The application creates multiple mates under certain conditions:
  • If the application finds circular edges to mate, it creates a peg-in-hole SmartMate.
  • If the application finds circular edges and a circular pattern that matches on both components, in addition to the peg-in-hole SmartMate, it adds a concentric mate to line up the patterns on flanges ( useful for pipe fittings).

    For more information on auto-mates, see Solidworks Help.

    Quick add special symbols to Solidworks

    When filling in those. requirements it is necessary to put a symbol of diameter, plus-minus, degree, etc. Adding using the symbol table is not fast. And in the design it is desirable to optimize the routine work, it means the design of the drawings.
    For example, to insert a symbol from a symbol table, you need to go through three menus, and then select the one you need from a large number of fonts. Yes, there is a huge choice in the symbol table, but the designer does not need technical requirements for it, it needs quite a few special symbols.
    Solidworks - Добавление спецсимволов
     Adding special symbols

    Solidworks - Библиотека обозначений
    The Symbol Library
    Solidworks - Таблица символов
    The Symbol Table

    If you apply a dimension, the symbol of diameter and degree can be added quickly.
    Solidworks - Добавление диаметра в размер
    Adding a diameter

    then in the notes so simply does not work. It will be necessary to make quite a large number of mouse clicks until you get to the required symbol. Fortunately, there is the ability to quickly enter special characters using ALT-codes. To enter a special character, press and hold ALT to enter the numeric character code.
    List of most frequently used:

    English keyboard!
    (±); input: ALT+0177
    (°); input: ALT+0176
    (²); input: ALT+0178
    (³); input: ALT+0179 
    (Ø); input: ALT+0216
    (ø); input: ALT+0248 

    Of course, on this list of ALT-codes is not limited, the full list can be found in nete, on the same wikipedia.
    I think that to speed up the input to remember a few digital codes will not be difficult, try. Of course, you can enter some special characters using internal Solidworks codes such as <MOD-DIAM>, <MOD-DEG>, <MOD-PM>. What is the analog of diameter, degree and plus or minus. But the ALT code is shorter and easier to type.

    Macro for creating a spring

    The spring is one of the standard products, which is often used, but it is desirable to automate the simulation. Fortunately, there are enthusiasts who undertake this work. Macro for creating springs of tension and compression "SpringSW" - author of Shvg. To use the macro, you must add it to add-ins. To do this, open "SpringSW.dll", then "Spring" will appear in the "Tools" menu. Use the look at the video. For the coupling of the spring into the part, there is an axis "Axis1". The build tree is hidden, but it's even better. The spring has several configurations in different states: compressed, working, etc. The macro allows you to build compression springs and also to edit the data. Easy and convenient to use.

    Administrator rights are required to install and use the macro. You can change the shortcut to start

    Localized interface in Solidworks

    Often, after the installation of the localized version of Solidworks user instead of Russian or Chinese, Polish (depending on the native language) interface sees the English interface. What to do? 

    Step 1. For the beginning it is necessary to check whether the set your locale (locale) in Windows.

    Region and Language Settings
    Region and Language Settings

    If not installed, install and run the solid. Did not help?

    Step 2.

    As a rule, it is sufficient in the settings Solidworks uncheck "Use English Language menus" (use the English menu) and restart Solidworks, so there was a Russian interface.

    Uncheck, so it was like on the screenshot below, click "OK" and restart Solidworks.

    Did not help? There is a way that will show who's boss :).

    Step 3.

    It is necessary to rename the folder with the Russian on the English language resources, and English to Russian (in fact the latter, at the discretion on any name). Folders with resources are default:

    versions prior to SolidWorks 2009

    "C:\Program Files\SolidWorks\lang\english" - English resources

    "C:\Program Files\SolidWorks\lang\russian" - Russian resources

    SolidWorks versions 2009 -2012

    "C:\Program Files\SolidWorks Corp\SolidWorks\lang\english"
    "C:\Program Files\SolidWorks Corp\SolidWorks\lang\russian"

    This procedure is available for other languages, respectively, you must rename the directory to the desired language, ie, French, German, Chinese, or some other.

    To change the language temporarily, you can use bat-files.

    Crashing Solidworks and the threshold of system resources

    I think everyone who modeled in Solidworks came across an unexpected program closure. Bouncing solid quite often, but as a rule, when complex models are opened and closed intensively or when they are saved, which is especially unpleasant.
    Do not all fall for the curvature of developers, they are trying to create a quality product. The reason for the unexpected collapse of Solidworks is the limitation of Windows that the process can only access 10,000 GDI objects.

    What is GDI?

    GDI objects are used to draw window elements that are not in the graphics area in SolidWorks. For maximum performance, the graphics area uses OpenGL, which gives more direct access to the equipment for video processing. GDI objects are used for the chrome graphic area, so every time a new document is opened, the number of GDI objects used by SOLIDWORKS will increase. Prior to this, SOLIDWORKS 2011 SP4, if the part was opened in the assembly and its own window, when this window was closed, it would not free these GDI objects. The default behavior is now to release these descriptors, but not all of them are released.

    Why is this all due to the failure of SOLIDWORKS? Windows has a default limitation that one process can access only 10,000 GDI objects. Because SolidWorks does not release all objects when the document is closed, the number it uses increases continuously with each new document and gradually approaches the limit set in Windows.

    Is it possible to use this knowledge to predict when SOLIDWORKS will knock out? 

    Predicting a SOLIDWORKS crashing

    As it was written above, this is not technically a failure, if SOLIDWORKS reaches the limit of 10,000 by object, Windows completes the process. This is not caused by a code error or by problems with shared memory access or anything else that causes a crash. It's just that Windows believes that SOLIDWORKS consumes too much resources and closes it to get those resources back. But since there is a certain number at which it closes, you can predict when it will happen. In fact, it's easy to control. Just follow these steps:

    • Open task manager (you can right click on the task bar and click task manager). 
    • Click View, Select Columns…
    Select Columns in Windows Task Manager

    Check off GDI and User Objects and click OK

    Display GDI Objects
    Now, the task manager will display the current value of the GDI and USER objects for each process

    Display GDI Objects
    Display GDI ObjectsIf a part is opened and closed several times the number of GDI objects it uses does not increase. SOLIDWORKS releases all handles every time.  The same applies to assemblies as well.  The problem is only encountered when a part is open in an assembly and it is opened in its own window and then closed.  
    How to troubleshoot this crash problems

    How can this problem be avoided? Do not keep your assemblies open unless you need them to be, and monitor your task manager periodically to see how many objects you are using.  Closing SOLIDWORKS and opening it will reset this count.  Furthermore you can increase the maximum number of GDI Objects a process can use by following these settings:
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota 

    • Sets the number of GDI objects, the range of values is 256 ~ 65536, the default is 10,000.

    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\USERProcessHandleQuota 

    • Sets the number of descriptors, the range of values is 200 ~ 18000, the default is 10 000.
    Increase the values and reduce the risk of Solidworks failure. When changing the parameters, switch to the decimal system of the calculus.

    When writing an article for testing, the parameters were reduced to 1500, after the Solidworks Resource Monitor warning, after some time the Solidworks was crashed. 

    The same manipulations apply only to the GDI problem, if SolidWorks Resource Monitor writes that there is not enough memory, then the problem will be to add RAM or unload other programs.
