lines versus overrides

I’ve used Architectural Desktop (version 2006) for a few projects. It’s the reason I like Revit as much as I do. The reasons I dislike ADT don’t belong in this post but one of the few things I did like about ADT was it’s ability to define lineweight by subdivisions. For example, being able to make the parts of an exterior elevation that are closest to you a heavier lineweight than those far away without having to edit the lines themselves. This is just proper drafting technique no matter where you are.

Regrettably, Revit programmers still haven’t copied (stolen, hacked) this concept from ADT. Actually there’s lots of concepts that I think Revit should have taken from ADT. Instead Autodesk opted to give us a linework where we can click on edges and set the weights to other than their defaults. I have also found this tool to be somewhat unpredictable. For example, when modifying the edge of a round column, the entire edge is modified even if the column disappears behind a wall halfway up. Also when modifying walls I have had linework disappear when I add an interior wall the joins to that exterior wall or if I split the exterior wall. This is a problem if you have multiple drafters on a project. It would be nice if Revit would flag an error that linework has been removed so you can go back later an fix it but it doesn’t.

Instead of using the linework tool, I’ve learned that using view and element overrides are for more dependable and stable. By selecting the walls closest in the view you can override the projection lines by element. This way if other drafters modify the model they are less likely to destroy linework.

The final point I’d like to make and I see lots of drafters making this error. Double check the drawings before issuing. It seems to be a bad habit that has come with 3D drafting that drafters just assume Revit will display everything just as they wanted. DON’T LET THE COMPUTER TELL YOU HOW TO DRAFT. Computers are stupid, people are smart. OK, most people are smart. Before you send out the drawings to be plotted full size. Print up an 11×17 set of drawings and take a moment to scan every detail for graphic errors. It only takes a few minutes to scan 30 sheets and you will save lot’s of aggravation down the road.

Sorry for the big post today. Hope it was worth the read.
