Curved wall thickness' change along the way (big failure in Revit)

JABKZR4YN · ‎10-25-2023

I have just experienced that the same wall has different thicknesses' along the curve. The profiles on the pictures are 95mm, the same as the gaps between the gypsum boards. But in some cases, the walls get slimmer - see how the profiles "goes" in the gypsum ball.

Has anyone experienced anything similar?

I feel that this is a big problem affecting many things, like areas, volumes, material take out and the layout of buildings.

this issue looks like it is because a "curve" is not a smooth curve, it is faceted. That is how Revit makes arcs and circles. an Arch or circle is made up of a series of short straight lines. The more/shorter the lines the smoother it looks.

i think there is a setting in the Options to control that. I don't have Revit open currently so I'd have to look it up though when i get to my desk. maybe someone else can chime in on the setting....

Don't zoom too much. Don't worry about this. Seriously.

It's hard t zoom out then it need to be detailed 😉

Turn off thin lines and look at it. Also what does it look like when printed.

This is just a graphical issue that will only be noticeable at a 1:1 or 1:2 scale when printed.

If you add radial dimensions to the 2 faces you are concerned with they will report the correct size.

Revit loses fidelity once you zoom to microscopic detail level. This is a known issue for a long time and we have been asking the Autodesk team to give us a better updated graphic engine instead of an outdated engine. Their limit object thickness limit is set to 1/32" or 0.8mm. This is why you give construction tolerance and print the set to see if that detail you look at is obviously wrong.

This is a common trap people fall into with Revit, "I modeled it so I can detail it....". people model extra small items thinking they can use it for making details later. Sometimes you can, sometimes it's better detailed using a 2D Detail with a Drafting view. Especially for enlarged details.

As @syman2000 mentioned, "This is a known issue for a long time ..."
