(WORKAROUND) Zoom to fit freeze 3d window?

When you use Std_ViewFitAll on an empty model the problem does not occur. A similar solution could be implemented for Std_ViewFitSelection when a point is selected.

unfortunately that doesn't work for me either. it is not a problem for me. I am currently developing a freecad training course. I run into this problem when doing an exercise. i will use 0.19.3 for this exercise and it will work around the problem

My previous post was a suggestion for Yorik.

Hmm yes... setting a minimum distance maybe, that might be a good idea indeed

I was able to reproduce the problem and saved the file at that state.
Unpacked the file and checked the camera settings at the very end of GuiDocument.xml

Code: Select all

<Camera settings="OrthographicCamera {&#10;  viewportMapping ADJUST_CAMERA&#10;  position -nan -nan -nan&#10;  orientation 0 0 1  0&#10;  nearDistance 0&#10;  farDistance 0&#10;  aspectRatio 1&#10;  focalDistance 0&#10;  height 0&#10;&#10;}&#10;"/>

Two strange things

• position is normally three floating point values (x,y,z) but -nan doesn't make any sense to me. Could also not find anything in the Coin-docs

• nearDistance clipping plane as well as farDistance clipping plane are set to 0. That means there is in fact no visible range for the camera

Please check that in your file and confirm.
