Topo in Section Cut – Bug?

In Revit on February 28, 2011 at 8:49 am

My standard when viewing a building section is to view *only* what the section line is cutting through – not the elements beyond. For this reason, after placing the section in plan view, I drag the bounding box line that represents the far clip offset really close (technical term) to the section line. I don’t see a way to set it to a distance of zero, so I just zoom in and eyeball it (technical term that comes from using Revit). The problem this causes is that where the section cuts through a toposurface the cut fill will not display.

When I increased the far clip offset to 1″ the cut pattern became visible. It turns invisible when the far clip offset is set to any value smaller than 0.89″ in fact. This seems to me to be a bug with the toposurface entity, since none of the other cut patterns in the model behave this way – they are consistently visible. Hopefully this tip will save somebody some time. I won’t say how much time it would have saved me because it’s just too darn embarrassing.

I’ve Fallen, and I Can’t Get Up!

One of the goals of this blog is to document my journey through learning Revit, and one of this project’s exercises provided some good inspiration.  (We’re in CDs now, but this was from schematic – I’m just now getting around to posting.)

I needed to create a trellis, and I decided to make it parametric, and face based.  Since it was in fact my first shot at a parametric family, there was a decent learning curve.  It took some time to get all my reference planes placed, named and flexing properly.  I placed my geometry (even needed some nested families), and everything looked great.  It wasn’t until I tried to place it on a wall in my project that I realized my mistake:

Apparently that un-deletable object at the bottom of the Generic Model face based template *is* the face to which the family is oriented. My family would have worked fine if I were attaching it to a horizontal surface, but I wanted it to attach to walls so I decided to rotate what I could in the family and re-create the rest. The good news? Work always goes faster the second time around.  .-)
