Triangulate a Distorted Face

Before going on with the Curtain Wall story, we have to stop for additional informations. The following technic will be useful for Adaptive Components too.
As nearly everything in Revit, this is a Workplain related story. All Point's and Line's Offset value works perpendicular to it's Host. The solution is easy againt, just try to think like Revit does ;)

Find the difference

When the Adaptive Components were implemented, they gave me many nigths of Googleing in hell of hell to recognize the possibilities. I would like to save your time by showing how to work with them.

1. We should not spend too much time on the one on the lefthand side. [On the image you can see "Használhatatlan" marked, it means Useless in Hungarian.] I just opened a template (Metric Curtain Panel Pattern Based.rft), and changed the Pattern to Triangle (flat) on the Properties Palette, after that just made a Form from the original Reference Lines.
   By this method the triangle based prisms open on convex faces and intersecting on concaves...
2. On the righthand side you can find a trick, to create a countinuous external face for the (Curtain) Wall. We just have to define the offseted corners.  
1. Open the template named above
2. use Reference Point Tool (as marked on image with 1-2.)
3. Set the Workplace on horizontal planes of the original point before placing a new (as marked 3-5.)
   
4. Repeat this to the rest two corners
5. Select the three new Point (you are going to pick the last placed ones by clicking on them)
6. Add an Offset on the Properties Palette (maybe you can assign a parameter if you want to)
7. Draw Reference Lines with 3D Snap (you can find this on the Options Bar)
8. Create a Form from the upper and the original Reference Line chain

We are ready to use the Panel on next week.

For Revit gourmands a small comment:
The Offset is true perpendicular to the corners, and it is NOT the real thickness of the truncated pyramid shaped panel. There are solutions to corrigate this, I may show some of them in later posts.
