Create a Surface from Existing Points

To create a surface, the reference model must have at least three existing points available. You can select the points that will be used to create the surface prior to initiating the surface creation command, or they can be selected during creation.

1. [Optional] Select points in the display.

2. Select the (New Feature, Surface) From Existing Points command.

 

Menu

Model > New Feature > Surface > From Existing Points

Tool

Pop-up

Create New Surface

The Create New Surface dialog box is displayed.

The dialog box displays all existing points for the currently open reference model. If points were selected beforehand, you can filter the list to show just these points.

3. [Optional] To display only previously selected points, select the Only selected items option.

4. Press and hold the <Ctrl> key, then select the points to include in the new surface.

You can select as many points as you want, but you must select at least three.

You may also create circular surfaces in your reference model. Circular surfaces are defined by a centre point and a radius value. All circular surfaces are horizontal (at a single elevation).

5. [Optional] To create a circular surface, choose the Circular option and type a value in the Radius field.

6. Click OK.

The name of the new surface is displayed in the Identification tab of the Model Feature window.

Using tabs in the Model Feature window, you can change the settings for a surface at any time.

The points that make up the new surface are displayed in the Spatial tab.

If you selected points to create a convex shape, these points are displayed with an asterisk (*) in front of them. This means you must sort these points manually.
