Curved Ramp 2.0.0

About This File

This Marionette object is a path-based ramp. The path is a bezier curve and can be reshaped by double-clicking on the object. The 3D ramp is built by lofting NURBS curves and the 2D text can be turned on or off in the Object Info palette.


This ramp uses the new Valve node in Vectorworks 2018 which means it can't be exported back to 2017.

I have updated the curved ramp to rise based on tangency as opposed to distance. Please let me know if this solves or exacerbates the cross slope problem. I also set the vertices of the path to be arc vertices - these can be changed using the reshape tool.

I like it a lot. We need to look into other great site related scripts.

Hi Sarah,


Thanks for this! It is great and I can already see the wheels turning on all the time I have spent trying to model complex curvilinear ramps.


Two comments:

1. Is there any way to make the horizontal curvature more regular? I know this is using nurbs, so the answer may very well be no, but we often are trying to design ramps on a radius which is difficult to do accurately with nurbs or bezier curves.

2. The cross slope profile created by the loft surface can create some pretty extreme cross slopes. Is there a way to better control this?
