I have been using THERM 7.8.77 for a while. Due to a hardware upgrade I had to reinstall the same version THERM and WINDOW.

After the reinstall THERM is not working properly. I am not able to draw the curves of the profile i am trying to draw.
Every time I switch from a straight line to curve as shown in picture its giving me an error " Overlapping regions are not allowed".

Please help to resolve this issue. Already tried reinstalling the software once.

Hi,

would you please share your model in order to let some of the forum users help you?

I don't know what procedure you've been using to create models in Therm before the hardware upgrade.

As many Therm users do, I personally always draw my models in AutoCAD (an ACAD polyline for every Therm polygon, no doughnut shapes, near the origin of UCS World and in the positive quadrant), export in dxf and use "File/Underlay..." function selecting "Autoconvert" .... and generally it works without problems.

I rarely draw them directly in Therm, because, honestly, it can be a nerve-wracking task... ;-)
