Create Back Outer Boundary

For this part, we will start with bottom up approach where we first create vertices and then using the vertices to create edges. Create the following vertices.

Operation Toolpad > Geometry Command Button Image Added > Vertex Command Button Image Added > Create Vertex Image Added

Create the vertices by entering the coordinates under Global.

Click the FIT TO WINDOW button to scale the display so that you can see all the vertices.

Connect the vertices to create three edges

Operation Toolpad > Geometry Command Button Image Added > Edge Command Button Image Added > Create Edge Image Added
