(WORKAROUND) Help interpreting an error message

[thomas-neemann]

What could this error message mean?

Is the model still usable?

Code: Select all

07:00:55  <Part> ViewProviderExt.cpp(1266): Cannot compute Inventor representation for the shape of rep20_24he_waermetauscher_8jun658#Compound036011: Bnd_Box is void

workaround

If I select everything via box selection and create a simple copy and only continue to work with the copies, the error message is gone

Very hard to tell a) without the model and b) without knowing what you intend to do with it.

[thomas-neemann]

I got the model from another freecd user to expand it. under time pressure i added freecad geometry, a mesh and some step files. During this time, error messages appeared, but I couldn't take care of them due to time constraints. now I would like to eliminate the error messages afterwards and for the future I only need the geometry without parametric but with color information. I succeeded with the workaround.

The error message points to an object that has an empty shape.

Thanks for the info. through which workflow can something like this arise, for example?

Didn't it happen with your workflow? I don't understand why you are not providing the file and give a detailed description of what you have done if you want more information. Meshes are always candidates for having an emnpty shape.

For example a Part_Common will produce this error if the original objects no longer overlap.

[thomas-neemann]

that won't be of much use because i took over the file and don't know how it came about. I also have no influence on the step files and the mesh. It helps me if I know that e.g. step files can cause such problems.

thanks this is helpful for me
