Please forgive my ignorance. I'm somewhat of a newbie. Running TurboCad Pro v5 on mac. I'm doing a simple 3D sub-basement plan. Just footers, walls and a finished floor grade. I'm trying to add an electrical conduit layer. I'm not exactly sure how to draw the .75" and 1.25" conduits in their proper places within the walls and footers. ie. a .75" conduit centered in a 10" wall that's 48" above the finished floor. I do understand the concept of X, Y and Z axis. Just can't seem to get it to match up. Again, I'm sorry for such a lame question. I'm not a pro and just trying to help a friend out with a drawing.
