Getting Started


Learn the basics of FlexTools in 9 simple steps!

1. Place a Flex component onto a wall component.  It automatically cuts an opening in the wall.

Important - The wall faces must have their normals facing out (blue in, white out), and they must be enclosed into a component. (Do not use groups!)


2. Move and Scale the component to fit exactly where you need it using Sketchup's native move and scale tools.

3. Change the Cutting Depth if there are multiple walls to cut through.

4. Adjust XYZ Dimensions / Distributions / Visibility ... of the various component elements through the Component Options Window.

To learn more about the options relevant to each component checkout the relevant learn pages in the menu on the right.

5. Copy the component around the model.  Scale and edit each copy as needed (Steps 2 & 3).

Components are scaled into existing openings (Cutting Depth set to 0)

6. Save the component with ComponentFinder.  You can then quickly pull it back in when you need it again.

📌 Materials applied to sub-components & Cutting Depth will be saved with the component.

7. You can manually edit the geometry that is inside each of the sub-components - just make sure that the boundaries of the sub-components are not changed!
8. To get the components to look correctly in plans and in sections, use the PlanView tool.

9. Use the various Tools for fine tuning and extra control.  Use the Opener to open and close all the door in the model.   Use zapper to disable the dynamic properties of a component for manual fine tunings, and use cleaner to make it cleaner and leaner...

Workflow with Non-Wall-Cutting Components

Flex components automatically cut openings through double faced walls by default.  If you do not want a component to cut openings automatically, you have the following options:

A. Enable the Place Upright Toggle (before placement!)

Rotate Component 90 Degrees


B. Set the Cutting Depth to 0.


C. Convert the component into a regular component.

Workflow in previous version of FlexTools

Before WallCutter was introduced, the FlexTools workflow was a bit different.  More about the Previous Workflow here.
