Drawing Architecture

If you're including architectural features in your sketches, a solid grasp of perspective drawing is critical. You don't have to do anything fancy - just understand how perspective 'works'. If you trust your eyes and draw what you see, you shouldn't run into any trouble; but often we subconsiously try to 'correct' things and so create errors. Understanding the basics of perspective will help you identify and issues.

Straight lines can be a problem. A ruled edge looks artificial when placed among freehand lines. Try placing the ruler or other straight-edge parallel to the line you want, so that you can run your finger, not the pencil, along the edge to guide your line. This can take a bit of practice to get right, but it's a useful way to create a more natural-looking straight line.

Of course, I'm thinking here of a cottage in a landscape or a simple urban wall and window. A cityscape in three-point perspective is going to be a little more challenging. A mathematically correct projection of an architectural plan - mm, nope, I did arts, not engineering!
