Mesh Design Workbench - Create mesh from shape - Coarse

Post by frcaduser »

Version: 0.19
Revision: 24291 (Git)
Rel. Date: 2021/04/15
Word Size: 64-bit
Op. Sys.: Windows 10 Version 2009

Hi,

here is what I am attempting to do:

I want to create a mesh from a shape/object from an existing step file that has been converted to a FreeCAD Document. The reason being is that I would like to create an stl file from it and reduce the file size. Here are the steps that are executed:

1. Make sure I am in the 'Mesh Design' workbench.
2. Select or highlight the object from the Model/Application sub-menu in the Combo View window from the current active application/project.
3. Go to the 'Meshes' menu and select 'Create mesh from shape ...'.
The 'Task' menu becomes active.
4. I select the 'Netgen' menu. In it, I click on the 'Fineness' sub-menu.
5. I select the 'Coarse' option.

If I go via this route, the application sometimes more than likely will hang up (freeze up).
If I bypass steps 4 and 5, and just click ok, it will work as expected (Moderate is the selection at default).

Has anyone experienced this issue? If so, has someone determined a workaround?
(sorry, I am unable to provide the project since it is proprietary)

I have attached a screenshot of the error that is displayed in the Report View window. Note that I was able to create a mesh of the object this time yet I still received this error when executing steps 1-5 above. This time I was lucky. Other times, the program just hangs up and it displays (Not Responding).

do you want to reduce the file size to be able to work faster?

Hi,

the reason is not to work faster but to create smaller resultant stl files. Of course, if there is a faster method, I am always open to new and better methods and/or ideas.

in my attempts with large files, .iv was the fastest option, e.g. at the loading times

You can try to decimate the mesh after it is created. This should reduce the file size of the exported STL.
