I have an ai file that I have placed onto an IsoDraw template. I have ungrouped it so I can select the objects. Is there a way to change the opactiy of one of the objects?
Unfortunately, you can change the opacity in IsoDraw neither on lines nor on fillings. Sometimes it would be useful.
If it's really important, I try elaborate tricks: I change the bottom elements on a light gray. After that I set them on at a higher level. Then it looks like as if the opacity is lower.
