create new Planar Surface

Here we will learn to create a planar surface.
To create a planar surface can be done by:
A sketch of non-intersecting closed
A set of closed edges
Some co-planar parting lines
A pair of planar entities such as curves or edges

To create a planar surface is limited from the sketch:
Create contour,non-intersecting, closed with a sketch.
Surface Planar surfaces Click on the toolbar, or click Insert, Surface,Planar.
In PropertyManager,select the sketch in the graphic or design to
limit tree FeatureManager Entities.
Click OK.

To edit a planar surface:
If the planar surface created from a sketch, we can edit the sketch.
If the planar surface created from a set of edges closed, right click
and select Edit Feature surface.
