Does anyone know a good source on the web to learn how to use matrix transforms? I've been trying to figure out how to extend the length of a line by a given amount and just can't seem to pin it down. I'm also planning on doing so 3D stuff later on so I'd like to figure out how they work.

What is a "matrix transforms"? Certainly not Revit terms. Did you read the similar threads below? (Unlinked code matrix) | | \/

if you are going to do stuff like that, you will probably have to interface through the API and some other programing langauge. why you want to do this in Revit??? i don't know. to each his own. check over at AUGI with the API guys. they can probably point you in the right direction. hth

Perhaps you should look at this and talk to Mr. Spot: http://blog.cadway.com.au/search?updated-min=2009-01-01T00%3A00%3A00%2B10%3A00&updated-max=2010-01-01T00%3A00%3A00%2B10%3A00&max-results=7 Is that what you are trying to do?

I just can't figure out how it works and want to learn. If you want to move or rotate objects via the API you have to know how it works. In my case I want to extend the length of a line (via the API) so I need to apply a transform to a vertex (hence matrix math is needed). I realize I can also do this with basic trig but since I want to write some apps that deal with 3D objects later on, I figured I might as well learn now.

I didn't see anything that looked like API stuff on his blog. I'll send him a note but I think Mr.Spot is focused more on creating custom content instead of programming.

here are few Revit programing sites if you don't already have them http://thebuildingcoder.typepad.com/ http://cadappdev.blogspot.com/ http://revit-programmer.blogspot.com/ hth
