How do I convert walls to trim, and vice versa, in 3D design?

Use the Convert 3D editing tool to create horizontal trims, brick bases, and more.

Updated over a month ago

Whether you are adding a horizontal transition trim, creating a brick or masonry base, or adjusting window details, the 3D editing tool, Convert, lets you make clean, accurate updates directly to the 3D model.

Converting a wall to trim


The conversion tool makes it easy to transform a wall into a trim (for features like horizontal trim).

  • After creating a split, select the new wall segment

  • Click Convert to Trim from the action bar

  • The segment automatically becomes a trim and inherits the color and style of your existing trims

  • To ensure consistency, use Select All Trims to verify that your belly band matches other trim elements

Converting trim to a wall


You can also use the conversion tool to transform trim into a wall (for features like a stone base).

  • Select an existing trim segment (for example, at the base of a wall)

  • Click Convert to Wall

  • The segment now behaves like a wall surface, perfect for applying wall materials like brick or siding to create a stone base or other architectural bases

TIP: Use conversion tools to maintain realistic continuity between material types (for example, extending brick details below transition trim).
