Operating system: window 7
Slicer version: 4.9.0
Expected behavior:
Actual behavior:

The model was created using the model maker module.
However, the information disappeared in the CT 2D viewer.
What’s the reason?
1251

pls try to click the “centry” key and what will happen?

Is it right to say the window at the top of the 2D viewer?

If so, The “centry” key does not work.

Since Segmentations and Segment Editor modules have been introduced, I would not recommend using model maker module.

You can create nice segmentations using Segment editor module and export the result directly to STL/OBJ files.
