Split Bounded Plate Bounding Elements using a Plane
- Last UpdatedMar 05, 2026
- 3 minute read
Splits bounded plate bounding elements using a plane created from a maximum of three identified points.
If you split bounding elements using a one point plane, the split plane is defined by the working plane of the PowerCompass. Refer to PowerCompass™ for further information.
To set the PowerCompass orientation, select Use LCS on the PowerCompass.

Select an element to define the working plane. The example displays a defined working plane using a selected bracing element.

If you split bounding elements using a two point plane or three point plane, the split plane is defined by the picked points without the need for the PowerCompass.
For the purposes of this guide, splitting using a three point plane is described.
On the Sections tab, in the Modify group, select Split.
Alternatively, on the Plates tab, in the Modify group, select Split.
Note:
If the bounded plate is selected as an element to split, it will be split as well
as the bounding elements.
You are prompted to Select element(s) to split
Note:
The prompt does not display if the bounding element is already selected.
Click to identify a bounding element to split.
You are then prompted to Select element(s) to split or <Next>
Note:
The prompt does not display if the bounding element is already selected.
The prompt is repeated, allowing you to identify multiple bounding elements to split.
Input N at the prompt and press Enter to specify the split plane.
You are then prompted to Select element(s) to split with or <Plane (1 point)>
Input 3 at the prompt and press Enter to specify the plane.
You are then prompted to Select first point or
Input values in the dimension fields and press Enter or click to identify the first point of the plane.
You are then prompted to Select second point or <Finish>
Input values in the dimension fields and press Enter or click to identify the second point of the plane.
You are then prompted to Select third point or <Finish>
Input a dimensional value in the field and press Enter or click to identify the third point of the plane.
The bounding elements are split at the intersection with the plane.
Throughout the split process you can press ESC to cancel the command. Additional functionality is also available.

Next |
Press the down arrow key and select Next to proceed to the next split process. |
|
Plane (1 point) |
Press the down arrow key and select Plane (1 point) to split a bounding element using a plane defined by one picked point. |
|
Plane (2 points) |
Press the down arrow key and select Plane (2 points) to split a bounding element using a plane defined by two picked points. |
|
Plane (3 points) |
Press the down arrow key and select Plane (3 points) to split a bounding element using a plane defined by three picked points. |
|
Back |
Press the down arrow key and select Back to undo the last action. |
|
Finish |
Press the down arrow key and select Finish to end the command. |

The new GENSEC elements display in the Model Explorer. Refer to Split Bounded Plate Bounding Element Structural Connections for further information.
