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…

Please internalize your crv’s , or attach your .3dm file . [image] Help Us Help You You can use the Internalise Data menu option to cut everything to the left of a parameter:

sure, here is the rhino file cultural centre.3dm (5.8 MB)

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

would there be any reason when trying to interpolate curves through the rails to sweep along later it becomes haywire [image] CCentre facade framesa.gh (17.5 KB)

Curve contianer is not internalized: [image] [image] hamish: Would there be any reason when trying to interpolate curves through the rails to sweep along later it becomes haywire? Probably data structure issues.

CCentre facade framesa.gh (754.0 KB) the curves should now be internalized i think

The frames were all out of order. Here a solution: [image] rhino frames VR 02.gh (772.7 KB)
