1. In the plan view, the user picks the slab that the PT bundle will be located within.
2. In the Options Bar the user will pick either Banded or Distributed.
3. Revit will enter Edit mode, and the user will sketch in the tendon using the line tools, or imported geometry.
4. By default the tendon will be centered in the slab, but there will be an option called Pick Points (or similar) that allows the user to pick points along the sketched line.
5. When the points have been picked, the user will select Modify.
6. The user will pick each point, and will specify that point's height in the slab, for example: the tendon is in an 8" concrete slab and the user modifies the point to read 7". The tendon will now run through the slab at 7" from the bottom of the slab.
7. The user continues to pick each point to specify the height of the tendon within the slab until all points have been specified.
8. The user will now select Finish Sketch.
9. The completed tendon will have a direction associated with it, with an arrow at the head, and a tail symbol of some kind at the tail. Just as with walls, etc. the user will be able to flip the direction of the tendon using the change direction arrows.
10. There will be a tension value tag associated with the head of the tendon. This value will be filled by the user.
11. This would also work in concrete beams as well.
Please let me know if this makes sense or if it needs further clarification. A tool like this would take us one step more out of AutoCAD and fully into Revit!
