Hi Julian, see if your installed updates (Windows Updates), if Microsoft NET framework 4.7 is installed. If so you may need to reinstall this.
installing Microsoft® .NET Framework 4.7 on Windows® 7 or upgrading to Windows
10 Creators edition, how do I resolve instability with .NET Framework
functionality within the SOLIDWORKS® software?
users who install the Microsoft® KB3186497 or KB4104606 update to install .NET
Framework 4.7 on Windows® 7 may see instability issues in SOLIDWORKS when using
Additionally, SOLIDWORKS users who upgrade to the Windows 10 Creators edition
may experience similar issues when using .NET functionality. The Windows 10
Creators edition includes .NET Framework 4.7.
For example, the operating system might crash or hang when you perform any of
the following functions:
• Create a reference plane
• Delete a face of a solid body
• Use the 'Convert to Sheet Metal' command
• Use the 'Custom Properties' tab
• Use the 'Convert Entities' command
If the computer crashes when performing such actions, SOLIDWORKS Technical
Support recommends that you follow the instructions provided by Microsoft at
the following link to repair the .NET Framework 4.7 installation:
Follow the steps at the previous link to uninstall and reinstall .NET Framework
Windows 10 Creators Edition
Download the file 'sldworks.exe.config' from the link below and place the file
in your SOLIDWORKS installation folder (that contains the file ‘sldworks.exe’).
The 'sldworks.exe.config' file will disable touch and stylus support for
the SOLIDWORKS application.
NOTE: This is a temporary solution while Microsoft works on a solution for this
You will have to PM me for the link to the sldworks.exe.config file.
Thanks for the reply Adam, I will try that now and let you know how I get on.
Apparently none of the above fixes applied to my PC. I am running Win10 with all the latest updates etc.
I finally fixed the issue I was having by running a repair on my SW install.
Looks like 2018 has jumped to SP0.1, maybe an update will help?
I have now updated to SP0.1 which was fine for a while with no crashes on plane creation, but now it has started crashing again every time I create a plane.
I don't seem to have any problems with the other crashes listed above, just plane creation.
Julian, if you create a block with an extrude and use Insert > Sheet Metal > Convert to Sheet Metal, do you also get a crash? Both this feature and reference planes use .NET framework so it still could be the case there is something up with this. Maybe see if any Windows updates can be found and install, and then reboot. Or if not, look through your Windows Update history to see if .NET has had any changes made to it.
Adam, convert to sheet metal is ok, no crash.
I run the SW install repair and it will be ok for a few hours, but eventually it crashes and after that first crash, it will crash every time I try to create a plane. I guess that once it crashes, it must corrupt something somewhere.
Hi Julian, I think it is time to involve your VAR now as they can take very specific logs from your machine. I would go down the route of a Process Monitor log which reviews what SolidWorks is externally interacting with when it attempts to create the plane once the crashing starts. Have you a ticket open with your reseller?
Thanks for your help Adam, I think you are right, I will contact them.
I thought I'd try here first in case others were having issues.
