View Full Version : Post-Tensioning
Does Revit have a family for post-tensioning ie; tendons, dead end anchors, stressing end anchors, and if not has anyone created one?

Out of the Box - I haven't seen yet, so do Bridges.
Til then user should be able to create its own.
If Revit does it would be nice to see parametric tendon profile in a polynomial equation and limits zones kind of sweep profiles bounding box so user can define limits thru Dialogue Box rather than diging deeper.
Property boxes where user should be able to enter polynomials shapes and a f(x,y,z,t) limit extents for shape function and have a check box that will allow intrusion into that zone with Y/N to other objects.
Seems like this should be posted on a wishlist!

I would suggest line-based detail component families if a 2-d plan representation is all you require. Use nested symbol families for the tendon ends.
For non-linear tendons you would be limitted to detail/model lines.
I would avoid splines whenever possible. (use arcs instead)
You can then create a symbol family for consistant placement of the drapes. By using the spacebar during placement the family can even rotate in respect to the arcs. (doesnt work with splines)
I played around with some model families creating a 3d tendons. It was quite cumbersome because most of our projects have comlex pt layouts. Graphically the 3-d tendons also had many display issues. Performance was also hindered even though only a small amount of tendons were placed.
I agree that this is a tool that revit structure should contain but until then I think 2-d families are fine.
