Changing view to an object face

[WhoCanDo]

I have created a 3D angle 125 high and 75 wide.

In top view I am looking at the top of the back of the 125 and I can see the 75 flange at the bottom.

I rotate the angle -43.4?

From the front view I rotate the angle 19?

Looking at the top view again you should see a leaning angle at -45? or 135? depending on your point of view.

Keeping in mind that I may not know the method above used to create the end result how do I set the working plane to be the angles back face?

I would Open Gl render the angle

Shift C to 3d Rotate to the required face.

Shift-1 to activate the Set Working Plane tool. Use the Planar Face mode and click on the Center of the face.

On the Working Plane Palette click the Eye button to view the WP orthogonally.

Click Add on the WP Palette and give it a nice name.

Fantastic bcd, Thanks

One small problem. This works when the object is extruded but doesn't work when the object is created using the 3D Polygon tool.

Lets say I have a similar angle problem as above but I only have angles either side and not the angle itself. The angles either side are also at different angles? so I was planning on filling in the back of the missing angle with a 3D Polygon and using bcd's method to set the working plan and then draw the 3D missing angle but the working plane tool does not pick the 3D Polygon.

You can see I don't do much more than simple 3D so this one is a challenge for me at the moment.

Any more suggestions?

Trevor, I can't get what you are trying to do. Can you post an image.

The Set Working Plane tool does work on 3D polygons in both modes.
