I have two questions (that I will ask in separate messages). 1) What does one do when a model created by the sweep function in MacroModel 1.5 for the Mac does not have capped ends? I have made sure "End Caps" in the Preferences is checked, but the sweep doesn't close. I am trying to make a column that has surface detail, so my sweep profile is not a simple shape. I am also changing the proportion of the end of the sweep, so the column tapers at the top. I am creating the profiles in Vellum, exporting a .dxf file, then selecting the bits and pieces of my profile in MacroModel and joining them to make the profile. All of that works, except my model won't close. Anything I'm missing? Thanks!

I haven't worked with Vellum's DXF files, so I can't speak from experience here. From the symptoms you describe I suspect the DXF segments are not fully joined together. MacroModel will create endcaps for solid shapes, not open shapes. Even if endpoints for two different lines are coincident, they will not be necessarily joined. The DXF stage complicates things greatly. I'd try a couple of things: ** Marquee-select all profile segments and choose "Join" from the object menu. ** If that does not work, open the profile for editing and try to tease apart the endpoints. It may be that only one vertice is left open — MacroModel will not "join" these, as it's already a single line. Solution: option-click anywhere on the profile with the Trim tool to make two distinct segments, then join them. ** It may be that the DXF is totally funky. I try to avoid the format, myself. If you can export as PostScript curves from Vellum, this might be more robust. ** You can always use the Vellum DXF as a template for 2D MacroModel drawing, or design from scratch in MacroModel itself. Hope one of these does the trick!
