text: how can i draw a compound angle in autocad? i have 2 trapazoid shapes connecting @ -30 degrees in a side view and -15 degrees in a top view.  how can i recreate this compound angle on a 2d drawing to show the correct correction? use the " flatten " command, follow these procedures: 1- you have to be in the plan view, do this by typing "plan" then press enter twice 2- type"flatten" and this is an express command, if there's a "unknown command" message, then go to autodesk.com and download the express tools 3- chose your compound angle, press enter twice note: the flatten command sometimes works better with simple objects "lines better than polylines, faces better than 3d solids", so please explode the objects would be a good idea before giving the command.
