1- I can't see the details of İdecad steel scissors under the drawing command on the scissors, only anted appears. Where else can I see it? All steel construction details are not visible even though I have attached their drawings. 2- Which carrier system should I choose in the tdy 2018 wizard while making residential roof drawings? For example, I added a steel construction roof on a reinforced concrete building. There are both steel and reinforced concrete in the drawing. The main carrier is reinforced concrete, but do I need to solve the roof with steel? 3- I finished Idecad reinforced concrete drawing. I finished the roof drawing at idecad steel. How can I add a steel drawing on a reinforced concrete drawing? If you ask why you need such a thing, although my computer has an i7 processor, there were contractions. That's why there were shutdowns in idecad.
