The tools for editing an in-place mass differ depending on the environment. For example, the shape handles used while editing an in-place mass in the project environment are 2D. However, when you edit the in-place mass in the conceptual design environment, 3D controls allow you to further modify the mass by moving vertices, surfaces, edges, and points.
Use the following procedure to edit an in-place massing family that has been moved to the conceptual design environment from a project.
