How do I resize one side of a rectangle to form a trapezoid?? Can I adjust two nodes in line to a given distance?
You could try:
1. built-in perspective tool (effects> add perspective), and press ctrl+shift while moving top corner with mouse.
2. use a commercial macro - cadtool 5 - to generate trapezoid based on data. But you need coreldraw X4 or higher.
