Hey Richie! It's not that On Edge relations are all that bad. They can be useful in certain situations. It's just good to know about how they actually work and also how they can cause conflicts. does that make sense?

Now I think I am beginning to understand why certain things get screwed up. This is only the surface of what I still do not yet fully comprehend. Thanks.

an easy trick around convert entity problems, use composite curve for geometry that you need to convert, then convert the curve into converted entities, easily fixable - rebuilds 90% better than plain convert entities.

You can acheive a scale relation using construction lines and entities.

It seems odd to me. If a relation is being generated automatically, you would think that the software would be optimized to use it better. In this case, it takes longer. I need to check to see if the "Close to Model" command is using the "on edge" relation. I have started using it to knock of time closing up sketches.

Hey Rod, here's an example of a mortisse feature I created that uses a minimal number of relations and external relations to place it in a part. two picks and you've got a fairly complicated feature added!

Rod, in the tests I did, it took 6%+ to rebuild a feature using 'on edge' relations as opposed to one that used other 'manual' relations. Seems odd huh.

Devon, could you post an example of a library feature you have done showing how you have used the relations to make the feature more functional.

Long post Josh, but very informative. I have one question though, how much longer does the "on edge" relation take during a rebuild? Seems to me that the "collinear" relation would be very similar in taking longer to rebuild also.

It'd be awfully nice to have a "scale" relation. It'd let me define one line as one half (or any other ratio) of the length as the other. Yes, you can kind of accomplish this with "Equations," but it's just not a very elegant solution.

RE:"Use Parallel and Perpendicular Relations
When creating Library Features and want them to work, use parallel,perpendicular and symmetric relations instead of any others. This will help them work in any orientation."

That's a great Tip, I always forget this when I make a Library Feature.
