  2. Select and place any objects you'd like to use for your mantel in your plan.

    • Mantels can be found in the Core Catalogs> Architectural> Millwork> Mantels, Lintels, & Sills in the Straight and Surround folders

    • You can also browse to Core Catalogs> Architectural> Fireplaces for complete fireplaces of various styles

  3. Use Select Objects  to move and position the objects to your liking.

    Using the Move edit handle to reposition the object

  4. With the millwork object selected, click on the Open Object  edit button to open the Millwork Specification dialog:

Adding molding to the mantel
