Polygonal/circular rooms

[harbinger]

Coming back to SH3D after a couple of years to see how much the program has changed. There have been some nice features added, so i went ahead to see if i could transfer the floor plan i have on paper into SH3D.

Then i ran into a problem: i have 2 cylindrical staircase wells (equivalent to castle towers), and i couldn't find an easy way to create these circular rooms, either by the Add Room or Add Wall features. Windows will be added and there will be many cutaways (missing portions) of the cylindrical towers' walls.

Do i need to add this to the Wishlist or does the feature exist in another way, or maybe an easy workaround? [:-?]

Circular rooms can simply be made of two opposite round walls.
Adding windows to round windows should work better since version 5.5 but only if they have a rectangular cutout.
