As many of you know I took six weeks off this summer (hence the light blog posting) and Jay was kind enough to post some goodies for you while I was gone (Thanks Jay). Now that I am back I plan on getting back into it and getting some content posted for you all.
Since most of you like tips the most, that is what I thought I would start with. Once in a while I will need to create an extrusion with lots of holes or a certain shape that aren't pattern-able. If you look at the following image you would need to select 13 open profiles to do an extrusion cut. Imagine if you had many more than 13 and it would be a huge pain to select all the open profiles.
A little trick I use it to select the outer region and do an Intersect Extrusion so I only have to select one profile. Inadvertently if I try to select all the open profiles I miss-pick and have to start over so this save me lots of time.
Start the Extrude command and select the outer area as highlighted.
From there you can use the Extrude dialog box or Heads Up Display (HUD) to choose Intersect instead of Cut. Make sure you have the right direction and termination and select OK to finish the cut.
I hope that helps out next time you need to create an extrusion of many profiles that can't be patterned or mirrored.
