Problem in dividing curve mass surface equally!

[seejianfa356715]

Hi

I have a problem on dividing my Curve Mass surface into the distance that i want. My building floor height is 4.5m, i wish to divide the surface into 2 panels for each floor, thus i set a distance of 2250mm in the U grid, however, it is not matching of the floor level height that i have set. It seems to be offset more and more when the floor level go higher.

Below is the link to my image.

First, welcome to the forum. Now, about your question: Revit is doing exactly what you are telling it to do. Your instructions are making Revit divide the curved surface at a certain distance, which is being measured along the curve. The curve is longer than the vertical height of the building, and because of that the segments along the curve don't match the segments along the vertical height. You need to do the horizontal division using levels and/or named reference planes from a list of intersects. Check Wikihelp about the details on how to use intersects.
