The Revit family made in Revit 2017.
It contains 2 preset types - wheelchair with or without a person on 2d views. You can control the clearance line: to go without the line, choose the rectangular or circle clearance. No division by detail levels.
The family can be useful in architectural projects, where is important to show accessibility to the buildings. Also, I prepared the exports to FBX and 3D DWG formats.
I will be grateful for any feedback, thank you!
