How do I draw a slanted surface in isometric? Is it possible?
You can draw most surfaces in isometric projection (I have yet to find a view I can’t draw, but I don’t draw that much). The trick if possible is to avoid drawing the surface directly, and instead draw the surface between two reference points from other parts of the view (e.g. draw the top and the side elements which are along the projection axis, and just connect the points as needed). These slanted surfaces are known as oblique planes, and are often not represented accurately in an 3D view. For these more complicated views, you may want to draw the orthogonal views to show the full detail. However if an isometric view is not your cup of tea, use cabinet or cavalier projection. For more information and samples, try getting a hold of a technical drawing book, the local university or technical college should be well stocked.
