[image] I want to extract the shortest side (distance) of the rooms by using Dynamo …but the curves I got from dynamo are divided by connected adjacent wall which I don’t want. For example the rectangular room should has only 4 curves…but Dynamo report 5 curves instead. Any suggestion on this ?

To get the shortest distance from Room perimeter
