To Update a 2D or 3D Section

Use this procedure to update a 2D or 3D section to reflect changes you have made to the building model or to section line properties. For 2D sections, you also update the section to show changes made to the 2D section style. You can update a 2D or 3D section if you have not exploded the section, which destroys the link between the section and the building model.

When you update a section, you can add or remove objects from the section, change the location of the section in the drawing, and change the display set of the section.

If you do not need to change the section definition in any way, you can skip the following procedure. Instead, select the section you want to update, and click 2D Section/Elevation tabModify panelRefresh.
