Grasshopper frames on rails issues

[hamish4 (hamish)]

Hi all

I am trying to learn and implement grasshopper for the first time and place these “portal frames” that incrementally scale up and equally between the two rails/curves, i think? i have managed to dived each rail appropriately but trying to place the frames has led to this mess and have butted heads enough with AIs

Please internalize your crv’s , or attach your .3dm file .

@DavidRutten

You can use the Internalise Data menu option to cut everything to the left of a parameter:

For starters, your rails are going in opposite directions, and they have a different point count

You have a frame count that you can use to specify a number of subdivisions on each rail.

This is what the curve tangents are doing, which is probably not what you were looking for, you wanted vectors perpendicular to the tangents.

This might not be what you were expecting, but I think this is what you were trying to do with your script.

Here’s a version that makes more sense. The frames are scaled to accommodate the distance between rails at each pair of points.

Orient Direction doesn’t get enough love. Your cross-section is not planar.

unreal stuff

would there be any reason when trying to interpolate curves through the rails to sweep along later it becomes haywire

Curve contianer is not internalized:

Would there be any reason when trying to interpolate curves through the rails to sweep along later it becomes haywire?

Probably data structure issues.

the curves should now be internalized i think

[Volker_Rakow]

The frames were all out of order.

What did I do wrong?

Feels like the starting and ending profiles are oriented wrong, but otherwise everything else is “OK”.
