A few helpful hints
- Drawing cylindrical
projections along a 30 degree axis is tedious. Rotate in
120.0 degree increments until the shapes can be drawn
vertically. When you finish all of those projections,
rotate everything back to the correct orientation.
- When working with
orthographic guides (see "Converting…")
leave a duplicate of each face un-skewed off to the side.
Complex objects should be drawn in orthographic and then
skewed into the proper view.
- Once an object has been
created on any isometric axis it can be converted to the
other isometric axis by rotating it in 120 degree
increments and using horizontal and/or vertical
mirroring.
- When creating a gear-like
object, complete the round version (front view or
orthographic) and do 57.4 percent vertical scale. If the
orientation of objects around the main object is
important, rotate the round version 45 degrees before
scaling.
- Don’t be shy about
moving the faces around to compensate for the dimensional
offsets.
- The various transformations
used to create an isometric drawing can be saved as
presets or scripts. In CorelDRAW, you can assign
keyboard commands or create menu items to your scripts.
- Nearly everyone has trouble
drawing views looking up at an object. This solution
comes from Dick Barry, a long time friend and EXPERT isomatrician. Rotate your faces 180 degrees and draw the
object normally. When you are finished - rotate
everything 180 degrees again and you will have a view
looking up.

Exporting
- Avoid using CorelDRAW
features that are not supported in the target
application. For instance if you use a white patch to
hide something in CorelDRAW and then export it to *.dxf
the object you hid will show through a box (the patch)
with a black outline.
- Use a version of CorelDRAW
that you know has a reliable export filter. Generally
CorelDRAW 4.0, 7.0 and 9.0 are the best.
