Planar Surface


This topic will explain the Planar Surface function, will explain whereto find the function, and explain the options found in it.This topicwill also explain creation with quick steps and an example, and provide links to relatedtopics.

The Planar Surface Function

The Planar Surface function creates a planar surface from a closed 2Dgeometry chain.This can be one or more closed chains and the chains canalso be nested.

To open Planar Surface:

  • In the Surfaces group, of the Create 3D ribbon,click Planar.

The parameters display in the Data Entry Manager.

The Data Entry Parameters

  • Preview - Select the check box to enable the CAD preview, which displays what the result will be before you create it. Once all geometry is selected, the preview is shown.
    Preview - Clear the check box to turn off the CAD preview.

Selected Geometries

The Selected Geometries list, shows all entitieschosen for the creation of a Planar Surface.


(Delete) - removes the highlighted item from the Selected Geometry list.

(Delete All) - removes all entities from the Selected Geometry list.

The list will display all entities currently selected for the function.

  • OK - finalizes the function.

  • Cancel - exits the function.

Quick Steps - Planar Surface

  1. Open the function.

    The Selected Preview list automatically has focus.

  2. Select the 2D chains from which you wantto create the planar surface.

    This can be one or more chains, and you canuse single selection, window selection, or chain selection.

    The geometry is added the Selected Geometry list.

    A preview appears showing the current result.

  3. Click OK to confirm.

    The feature is added to the CAD Tree.

  4. Repeat as necessary.

  5. Click Cancel to exit the function.


Note: In theimages below, both the Show Axis X-Yand Show Gnomon toggles have beendisabled in the Axis X-Y groupof the Settings Part > Displaydialog.

  1. In the Quick Access Toolbar, click New.

  2. Click anywhere in the graphics area, to give it focus,and press Ctrl+7 to selectthe ISO 2 view.

  3. In the Shapes group, of the Create 2D ribbon,click Rectangle.

    The Rectangle parameters display in the Data Entry Manager and the Preview appears showing the default values.

  4. In the Corner Type group, click to create chamfered corners.

    The preview updates.

  5. Input 0.3750for the Chamfer Length.

    The Preview updates.

  6. In the Base Point group, leave the default value of 0.000 for the X,Y, and Zpositions and click OK toconfirm.

    A rectangle is created in the graphics area.

  7. In the Entity group, of the Create 2D ribbon, click the down arrow under Arc, and select Arc Center.

    The Arc Coordinate parameters display in the Data Entry Manager and the Preview appears showing the defaultvalues.

  8. Change the Radiusvalue to 0.3750.

    The Preview updates.

  9. Click OK toconfirm.

    An arc is created inside of the rectangle.

  10. In the Surfaces group, of the Create 3D ribbon,click Planar.

  11. While holding the Shift key, click on one of the entitiesthe rectangle is comprised of in order to select the entire chain.

    The individual entities the rectangle is comprised of are added tothe Selected Geometries list, and the Preview updates.

  12. Click on the arc to add it to the Selected Geometrieslist.

    The Preview updates.

  13. Click OK toconfirm.

    The Planar is created in the graphics area and a Plane Surface feature is addedto the CADTree.

  14. To end this function, click Cancel.

That concludes this example.
