I'm picking up grasshopper and have gone through many tutorials now, but something I am struggling to do seems to me like it should be quite simple. Basically, I am wanting to create a point on a line or a curve, and then use a slider of some sort (number slider maybe?) to move the point along the line or curve. Is this possible in Grasshopper? If so any help on this would be appreciated
Great stuff, thanks Brendon however I coulnt open the file, there were components missing from it so I assume we are using different GH versions. I did however manage to get something created bu creating my curve in Rhino, within GH i then set my curve in rhino to a curve parameter, fed this curve into a curve\analysis\point on curve, fed this result into a Point parameter and hey presto it moved along the curve using the point on curve slider!
There are three components that you should have a look at for this.
Evaluate Curve = Point on a curve based on the Domain. (Not always 0 to 1)
Evaluate Length = Point on a curve based on the Length Factor or the actual measurement.
Curve Point = Basic version of Evaluate Length giving a Point on the curve based solely on the Length Factor. This component combines the slider into it already
Thanks for the replies on this, some really useful info! On a side note, I have a new problem stemming from this which I have posted here if you would be kind enough to help? Thanks
