CRASH ON DIMENSIONING IN SECTION

VERSION: 2011 (update 1)

PROBLEM:

Crash Protection message when trying to dimension in a Section, Elevation or section Call-out.

POSSIBLE CAUSE:

Section, Elevation or section Call-out is not perpendicular to objects in the view, usually grids.

Revit aligns sections and elevations to the nearest object when they are created – usually a wall. If that wall is nearly, but not exactly, perpendicular to other objects you are dimensioning to, Revit poos itself.

If the angle is greater (i.e. more than 1 degree) it doesn't seem to have the same problem.

SOLUTION:

Align offending objects.

Unfortunately there is no way to re-align a section or elevation.

Create new Sections, Elevations and section Call-outs.

Use View Templates to match view settings to old Sections, Elevations or section Call-outs.

Open each old Section, Elevation or section Call-out, copy drafting objects.

Paste into new Section, Elevation or section Call-out.

Delete old Sections, Elevations or section Call-outs.

HOW TO AVOID:

Draw accurately!

Don't trace over CAD files, or anything from Rhino.

Check grids are perpendicular before using them to create objects.

Check by creating a Dimension Type with custom units.
