Overview

This feature lets you add custom trim to any shape you create on a wall. You can use it to:

  • Frame out wall niches or artwork areas

  • Create picture-frame molding or paneled wall effects

  • Match trim colors and finishes to your existing design elements

_______________________________________________________________________________________
Follow the steps below to learn how to apply trim molding directly to wall shapes and customize every detail.


Step 1. Open the Wall Surface Editor

  • In Perspective view, click directly on the wall you’d like to edit.

  • Select Edit Surface from the tooltip.

The wall surface editor will open, displaying your wall along with options for adding Material, Shapes, and Trims.


_______________________________________________________________________________________

Step 2. Add a Shape to the Wall

  • Open the Shape Library from the right-hand panel.

  • Select a shape (e.g., Rectangle) and click on the wall to place it.

Adjust its size by dragging the edges or entering measurements.


Notes: You can add your wall paint and trims before doing this step. If you would liek more details on adding paint and trims, these related articles will be attached at the bottom of this tutorial.

Step 3. Apply a Paint Color or Material to the Shape

  • Go to the Material/Color Library

  • Choose your desired Brand and color (example: Bedford Blue from Benjamin Moore).

  • Click on the color and then click on the shape to fill it with that color.

_____________________________________________________________________________________Step 4. Add and Customize Trim

  • With your shape selected, enable Add Trim by selecting the checkbox in the right-hand panel.

  • Select a Trim Style from the library (try a simple molding for picture-frame details or a thicker profile for accent walls).


Adjust the Trim Height and Depth as needed. These values are linked by default but can be unlinked for independent control.

Step 5. Fine-Tune Trim Placement

  • Use the Trim Offset and Rotation options if needed.

    • Offset moves trim away from the wall (usually not used for paneled walls).

    • Rotation changes trim orientation (0° keeps it flat).

  • Choose whether to position trim inside or outside the shape’s edges.

Use the Flip Horizontally or Flip Vertically options to change trim direction or orientation.

_______________________________________________________________________________________

Step 6. Apply Additional Trim Finishes

  • Choose a paint color or finish for the trim from the Color Library.


You can use the Recents tab to quickly reapply colors already used in your design.

_______________________________________________________________________________________
Step 7. Duplicate Shapes for Consistent Design

  • To create symmetrical panels, select your completed shape.

  • Click Copy, then drag the copy to a desired spot and click to set it in place.


  • Use the arrow keys to nudge and align duplicates using the red snap grid.


_______________________________________________________________________________________
Step 8. Copy Design to Other Walls

  • When finished, click Save.


To reuse your panel design, select the wall → click Copy, then click on another wall. You will get the option to apply it to that wall only or the entire room.

_______________________________________________________________________________________

Quick Notes

  • Keep Trim Offset and Rotation at zero when working with flat wall moldings.

  • Use the Flip tools to ensure trim details face the desired direction.

Trim colors and profiles can be reused quickly through your Recents list.
