As shown in the figure below, Zone A is the parking lot area, Zone B and Zone C and office and residential area respectively. The floor height and bottom elevation of Zone A are different from that of Zone B and Zone C. How can I draw Zone A easily and rapidly?
Deal with this problem by creating different zones:
1) On the PROJECT SETTINGS tab, click Floor Settings > Add, to create zones.
2) According to the drawing, enter the bottom elevation and floor height for corresponding zones.
