W.C. Casey sends us a neat trick to make hatch patterns look more authentic in a 2D elevation view.
"Elevation views are a standard part of any architectural drawing set, and hatch patterns — roof shingles, for instance — are a quick way to add some realism. But flat roof shingle hatch patterns look wrong when applied to a pitched roof surface in an elevation view. And what if your building includes a wing that branches off at an angle other than 90 degrees? Here's how to rotate the hatch to match the angle of your roof surface:
- In model space, draw a rectangle larger than your roof plane
- Fill it with the hatch pattern you want to use, then erase the rectangle
- Use the Modify > 3D Operation > Rotate 3D command to rotate the hatch in the x axis to match your roof pitch
- Use the same command to rotate the hatch in the y axis, if necessary, to match the floor plan angle of the building element
- Explode the hatch
- Use the Flatten command to convert the exploded 3D hatch to 2D
- Copy and Paste the pattern into your elevation
- Trim or erase the excess.
This same technique can be used on blocks such as windows and doors, or on a whole 2D building face."
Notes from Cadalyst Tip Patrol: Making our drawings look their best is part of the game we play. It took me a few tries to get the hang of this trick, but it did work. I would also suggest designing your model in 3D and using the Section command to instantly draw a section view (or elevation, in this case) of your model.
