Hello again,
I’ve been spending a fair amount of time with some architectural CAD friends recently, and thinking about best practices for using Inventor in construction. Quite frequently there has been a need to create architectural gridlines that need to be referenced both in the model and the drawing environment. Work planes would be the obvious choice for this, but it can be a little tiresome to create and name dozens of workplanes, as well as the parameters that control their offsets.
Architects don’t always use regularly spaced gridlines you see, so a pattern/array of planes won’t do the job…..
So I thought I’d invest a happy hour to write a quick iLogic macro to automate this for anyone in the same boat.
Just click on the picture above to see a quick video of this in action. Here is the iLogic code:
(As always be careful not to add new lines when copying and pasting this code into a new iLogic rule)
Enjoy!
