Anonymous

need to model a rafter/beam which is 4" x 8" at lower end and rises/ gradually curves(on lower side only down to floor) reaching 4"x 20" dimension at roof peak. Please help with modeling ideas. Have tried 2D drawing & magic wand/beam tool with no success. Thanks. jonC

Mesh?

ArchiForma?

Before you order, try tweaking Spiral ramp from the standard library.

My first though was roof, until I saw that the beam changes side.

I'm afraid Djordje is probably right.

post a better description. I would like to give it a try but I can understand it.

We had a similar object done some time ago. Here it is modified - hopefully it should cope with most situations?!

Note that ALL the vertices are stretchy hotspots!

Note that the two lines work to control the 'curveness' of the curve. Use ratios of 0.5 for a 'perfect' quarter-ellipse.
