As an old industrial visualization software, the current stability of DELTAGEN is disappointing.

Firstly, As my colleague @JV has posted, I also came across with the same issue.

3DSwym Could not import .CATPart and .igs file

Secondly for the turntable rendering, when I try to modfy the Start position, there is error as below and has to restart the software again. ​​​​​​​I hope the DG experts will take a look and help to solve​​​​​​​ asap.
