Booleans Mini Tutor: Impression

[maker]

Thanks to Dimitri for the inspiration (prev post)

Some situations in which mlab's Boolean tools may be used. Of course, there are many more - as you can see by looking at the videos linked from the mlab site (http://www.wings3d.net).

1. Using Boolean>Impression: Creating a road over the mountains


Some observations:

• Better to make a copy of the "base objects" in case of problems or changes.
• And also because the 2nd object (object used for creating the "stamp") is deleted.
• Materials are lost. (I was hoping that the "impressed" road would get the "road" material automatically )
• In case it does not come out alright, subdivide the "1st object" ("Landscape," here) and try again
  

I hope this will be useful to somebody. Good luck.

[Edit: I forgot to add. After selecting your 1st object, mlab automatically goes into sub-object (face / vertex / edge) mode. Don't let it bother you. Just select f / v / e belonging to your 2nd object. Mlab will do the needful.

Edit 2: Also forgot to mention: my other source of "inspiration." But, of course, any Wings3d regular will recognise it - puzzledpaul's quite wonderful how-to's & (not-so-comic) strips. Just the right thing if you're stuck, and have got your basics right with fonte boa's video tutors.]
