I am a newbie to Dynamo and was studying Design Script. While doing so I came upon a script example that asked for the extraction of surface geometry of a cuboid. The argument went: Cuboid.Faces.SurfaceGeometry() Cuboid here was predefined in a variable. Now the question is, when I usually enter …

Point at parameter is an action in the library. As such you need to declare the surface you are taking action on. Autodesk.Surface is the class for surfaces. surface is the name of the variable which is provided in your definition’s first line. By typing surface.PointAtParameter(0.5,0.5) you are …

Honestly the line Cuboid.Faces.SurfaceGeometry(c); is problematic, and likely never worked though I would be curious to see the tutorial you reference to know if/how it worked. Object oriented programming (which design script is a type of) has a few concepts to cover. Objects which are the things…

Now that that is out of the way, the autocomplete is not apt to work in a few situations. Offhand the most common are: Namespace collision. Civil 3D has this in MANY cases, where things existed in the Dynamo environment but Civil3D wanted them as well and wanted to keep them aligned to their API. …

Thank you @jacob.small , all of this is great help ! Although some of the terms and things you wrote I am not quite able to understand (being not accustomed to coding), but a lot of this makes sense. I think I liked the “Dynamo Language Manual” which was a saviour for me to learn the basics of the l…

This particular exercise above is also from the same Dynamo Language manual - So I was trying this out but unfortunately couldn’t find any node (in the node library) that extracts faces from a cuboid in Dynamo. Puzzling ! There are nodes for Topology, Solids but none to extract faces from cuboids. …

But it did work when I changed the class from ‘Autodesk.Surface’ to ‘Surface’: def makediagonal(surface) { corner_1 = surface.PointAtParameter(0,0); corner_2 = surface.PointAtParameter(1,0); corner_3 = surface.PointAtParameter(1,1); corner_4 = surface.PointAtParameter(0,1); diag_1 = Line.ByS…

hi too late [image] cordially christian.stan

Thank you so much @jacob.small & @christian.stan . Much appreciate the patience with novices like me. I might have made some repeated errors here. But that explanation clarified @jacob.small . I think the advantage of writing the longer way - Autodesk.Surface & then the surface within parenthesis is…

hi, i learned a lot thanks to this document and the help and advice of all (i am still learning) cordially christian.stan

DesignScript isn’t something that can document all the methods, as the methods will vary based on your environment. Your request thereof is less ‘where can I find documentation for Design Script?’ and more for ‘where can I find documentation for all the nodes in my library?’ which interestingly enou…
