I'm trying to dimension a 3D object - I've placed the dimensions on the design layer in an isometric view. I then created a viewport on a sheet layer. When rendered in anything other than wireframe or hidden line the dimensions are all messed up with overlapping text. The hidden line view takes FOREVER to generate. Is this a known issue? Also wonder how you control the size of the font this way? It is tiny even though the viewport and design layer are at same scale.
