My slicer keeps crashing during model making. I load my volume, adjust the dimensions and use the legacy editor to segment (it is what i am used to). After I have generated a label map, I will use the model maker button to make a model. Often times slicer crashes when I go to open model maker and observe the volume (mm3) of the model. I lose hours of work each time it crashes. Please help. I have a good graphics card and 32 gb memory.

Problem report for Slicer 4.11.20200930 win-amd64: [please describe expected and actual behavior]

Legacy Editor based workflows are not supported anymore. You can use Segment Editor module instead and enable 3D display by clicking on “Show 3D” button.

If you can reproduce a crash without using the legacy Editor module then please share the scene (upload somewhere and post the link here) and we’ll fix that. Thank you!
