I have seen that some floorplans have a platform/ height/ base to begin with and on top of that walls or structures are extruded or intruded with help of pish-pull tool. I have drawn this floorplan as my first attempt. Can anybody tell me how do I build a base/platform below this flat floorplan?
I take it that you want to create the basement underneat your floorplan.
Group all geometry that is in your current floorplan. (group, not component)
Copy your group (‘Move’ while hitting [ Ctrl] once to make the move a copy, see the + sign at the cursor) along the Z axis below the floorplan.
You can now work on the lower group in its editing context to convert it into the basement.
Thank you. I followed your technique and it worked. But by following this same technique, why am I not able to push-pull base under the floor plan next to the first one. 4 floor plan model.skp (202.9 KB)
