Sounds like you need a duplicate and mirror or a duplicate and rotate
operation.
Solution 1 (mirror):
- Rotate your object in the view your ascii art is in so it's at the slanted
angle you want (You can pivot around one of the top vertices for this using
the cursor as the pivot point.)
- Select your mesh and duplicate it
- Mirror around the vertical axis (Object->Mirror) or rotate it around the top
vertex
Solution 2 (rotate):
- Duplicate the mesh (Select, Shift-D, Escape)
- Select one of the meshes, tab for edit mode and select the topmost vertex
- Shift-S, cursor to selection
- Hit tab to get out of mesh edit mode
- Change the pivot point to cursor ("." (period) key - not the one on the
numad!)
- Now rotate each mesh clockwise or anticlockwise around the cursor pivot
point ("r" for rotate and use Ctrl for 5 degree steps and Ctrl-Shift for 1
degree steps)
Solution 3 (reconstruct another mesh vertex by vertex) :
- Extrude the bottom vertex one step to the left
- Select the bottom vertex and Shift-S, cursor to selection
- Move the bottom vertex the cursor is at one step to the right
- Set the pivot point to cursor ("." key - not numpad one!)
- Select both bottom vertices
- Hit S for scale and scale the vertices away from each other
- Repeat for each vertex and then reconstruct the faces on the one side
Probably best explained with pictures but I'd better not kill the SF lists.
The pivot around cursor is extremely useful and so are the constrain to axis
commands (Shift-<X,Y,Z>) which enable you to scale and move vertices around
but keep them locked to a single axis.
