I've made a nice endtable in CorelDream and exported as a dxf file. When I import it into Poser the top of the table is invisible - clearly it's got the normals the wrong way. I put an indent in the bottom of the top - if you turn the table over it looks realistic. The problem is that it's now impossible to select only the upper face of the top - anywhere I click will also select the lower face below it. Can somebody walk me through fixing this?
