I am trying to insert a family along a curve, and then rotate it to point to the center or be on the normal at each point. I have tried to follow this post Place family along curve but it has not worked as intended. I am sure it is something minor that I am not doing, and I am only using the Fans be…

Thanks to @Dimitar_Venkov on this thread Align objects with a 3d curve I was able to resolve the issue. I modified some of the code blocks he used with core nodes now available, but it has resolved the problem for me currently. More complex curves may still need work, but thanks for all of the help. …

Measure the angle manually that’s required to align the first family to the horizontal line Generate a list of angles which increment by the angle of each segment (I.e. 180/count of segments). Plus 1 to 2 Use the resultant list of angles to rotate the list of Families

@Thomas_Mahon , thanks for the suggestion, but one I want to be able to handle more complex curves than just a semicircle, and two I would prefer not to do anything “manually”.

Agree, but you’ll quickly discover that trying to fully automate this will be fraught with problems and ultimately fail to achieve its main objective. For example: You could extract the curves from each Family then find the curve at the tip of the fin closest to the grid line, then work out the an…

To all useful ends, I’ve written something quite simple that works with regular curves: [image] [image] I created little circle faces along tangents to place instances on thanks to Springs node. For the moment, I can’t divide a spline equally, but there’s probably an answer to that somewhere (?)…

Hi everybody. I tried to do the same thing described above, placing a desk family along a spline, but i noticed 2 weird results: i) the PointAtParameter node does’nt place points at an equal distance. [Cattura%201] so i solved the issue as in the image below. [Capture] ii) when i run my script…

Hi, try to create instance along the curve to the tangent. By topology.face nodes seem has problems [image] Appreciate if someone can help ? [image]

@lee129us You could use Element.Faces instead. Also, ImportInstance.ByGeometry would be better.

Hi , thanks for your advise. I able to eliminate the error, but the last node output always " Null" . Can you assist to advise me if you also facing this issue [image]

The result data structure is not same with surface. You could check your list structure. And I prefer to use Dynamo node instead of custom packages. You could find same function node in familyinstance.
