The extend surface feature is part of the SOLIDWORKS surfacing functionality that allows a designer to extend a previously extruded surface. This, in a way, helps reduce the time taken in editing the extrude surface command. In this demo, I will be taking you through how you can make use of the feature.
The first thing we are required to have in order to make this happen is a surface. You can go on to create a plain flat surface or an irregular surface of your choosing. To create a surface we all know that a spline or line sketch is required.
Create a new part in SOLIDWORKS, and then specify a sketch on the front plane.
A sketch of such a cross-section should do.
Next, click on the surface extrude command. Notice the window below pops up under the feature manager tree.
You can choose a length of the extrusion from the window.
Clicking on the green marker sets up the surface. Next, we go on to initiate the extend surface command. Move to the surface tab and select the extend surface command.
Alternatively, you can go to the command window on the top right of the SOLIDWORKS window and search for the feature directly.
Select the surface or edge you want to extend. You can select either edge of the surface extrusion.
Selecting one of the edges as shown, you will notice that the surface extends in that direction by the distance specified. Also, you can choose the extension distance from the number of end conditions available, one being the up to surface condition.
With these simple steps, you are now able to use the extend surface command.
