When you have a non-orthogonal building model in Revit, you often need to create sections (or elevations) at various angles other than orthogonal. Normally you would want sections to be perpendicular/parallel to the angled model elements – the image above shows a section somewhat off parallel (much exaggerated version of a typical example where it may be slightly off).
If the section is not exactly perpendicular (or parallel) to objects in the model you can encounter some very frustrating problems:
- You may not be able to dimension sectioned elements
- 2D Symbolic lines in families may not show up (eg. door swing in elevation)
If you try to rotate the section to make it exactly perpendicular (or parallel) to objects in the model, it is not as easy as you might expect:
- One thing to avoid is measuring an angle and then typing in the measured angle during the rotate process – it is never accurate enough, even if you use several decimal points. Revit is extremely fussy about this -…
