LyleBrowning Posted March 14, 2013 Share Posted March 14, 2013 I"m working on a 3D model of a concrete gravity dam. I have subtracted several solids to place holes in the structure, to create the spillway and so forth. Just now I wanted to add a piece by subtracting a solid. I created the rectangle, extruded it, placed it and selected the 3d rectangle and the rest of the dam which was listed as a subtracted solid. But when I went to the Model menu, all of the choices were greyed out. What's going on? Thanks, Lyle Browning Quote Link to comment
