Let me describe the problem in English because that is a lot easier for me. I work on SAP2000 V14, every time I draw any area using "Quick Area" or "Rectangular Area" everything is alright and fine. Every slab panel shows clearly filled when I extrude. On the other hand, every area I draw using "poly area" shows like void even when I extrude. The slab I am trying to draw has ordinates on the X Axis as 0, 4.2, 3.4, 4.2 and on the Y Axis ordinates are 0, 3.2, 4.3, 3.5.
The first 6 slab panels are easy to draw using quick area but what about the remaining 3 slab panels that look like a triangle? Dr. Atef Iraqi drew these panels on SAP2000 v8 very easily just by introducing a slanted line and snapping to it, THIS DOES NOT WORK ON SAP2000 v14.
