Clip & Section | Intro to a Visual Workflow

This is an introductory tutorial for designers who want to learn how to clip parts of your model and set a clipping depth for visualization and presentation purposes. We will cover the ClippingPlane command and many of its options. Rhino’s new clipping plane allows for setting a depth and selectively clipping by including or excluding certain layers, objects, and views from the clipping plane.

Visually clipping and layering a project are great ways to communicate design intent.

(2 minutes) Learn how to clip parts of your model and set a clipping depth for visualization and presentation purposes

Before We Start

Let’s make sure we have set Rhino’s User Interface to a similar setup:

  1. Go to the Window menu
  2. Click on the submenu Window Layout
  3. Select Default Window Layout

This will configure the toolbars and panels to the same setup and location as the one used in this tutorial.

Now go down by the Status Bar and make sure everything is disabled except for OSnap and Gumball, which should be enabled. On the left, by the Osnap Control , make sure all OSnaps are unchecked and then check End. This is just to make our lives easier as we model.

As for the Gumball make sure it is set to Snappy Dragging so it references all OSnaps we mentioned in the tutorial. You can set this in the Command Line options for the GumballSettings command.

Download and Open the CS-Townhome-Start.3dm model.

Make a Clipping Plane

Run the Clipping Plane command using the vertical option, and let’s keep the depth to be infinite. Now, this clipping plane is only clipping the base of the townhouse.

As you drag the clipping plane, you can start to see the interior parts of your townhouse. You can zoom in to see more details, and you can keep dragging to see the other side of your model.

INFO
This is an extremely effective workflow for visualization and understanding your model.

Set Clipping Plane Depth

Now, if you want to see only a slice of your model, you can set the depth of your clipping plane to be of certain value.

While the clipping plane is selected, go to properties and click on the custom depth. A zero depth will create a thin slice of your section only. You can set the depth to be any value. Let’s set it for example to 5 feet.

And now, as you drag through your model, you will continue to see a 5 foot slice of your model.

TIPS
  • You can zoom to see more details.
  • You can rotate the view to see your model from all directions.
  • You can flip the direction of your clipping plane to see the opposite side of the slice.

Clip Parts of Your Model

In Rhino 8, you can choose to clip parts of your model.

For example, if you don’t want to clip the base of your model but want to see the rest of it, you can exclude the layer where the base is or exclude the object itself.

NOTE
As you can see now, the base is not clipped by the clipping plane, only the model is.

Change Clipping Plane Visibility

You can also make the clipping plane active or inactive in one or more views.

Let’s switch back to four views of the model, and you can choose to make the clipping plane active in top, front, and/or right views by clicking the checkbox next to that view in the clipping plane’s properties panel.

Three of our views are set to monochrome, let’s set the top view to be monochrome the display mode as well for consistency.

SUCCESS!
Congratulations on completing this tutorial! Feel free to continue using these tools to visually communicate your design intent. If you have any questions ask us on Discourse or send us an e-mail at tech@mcneel.com.
