Hi there
I am fairly new to Rhino and a total noob with grasshopper. I am trying to model a stretch tent/tensile structure and by following tutorials and exhaustive research I have managed to create a mesh that is close to what I need using grasshopper/kangaroo. But I am totally stumped on how to fine tune the mesh to create a more realistic shape. Specifically on whether it is possible to manipulate only certain parts of a mesh (using vertexloads/edgelenghts?) I am trying to relax the mesh around the poles of the tent to more closely simulate what it would look like when the tent poles are pushed in at that angle as well as reduce the convex curve(ridge) between the two main kingpoles. I currently use vertex loads and lengthfactor(edgelengths) to manipulate the whole mesh but invariably end up with it ballooning or with saggy edges when I start to get closer to the shape I want. Any help/suggestions would be very much appreciated!

@Pieter2 The problem is that you’re selecting points on a flat mesh instead of points on an inflated mesh which you ‘attach’ to the tent poles. Probably the best way to do this is to use a two-stage approach. Take a look!
Just remember to only have one K2 solver block enabled at a time in this script.

I had no time to look at the file yet.
However, this got me thinking:
The anchor goal has a target point input exactly for that.
@Pieter2 Did this answer your question?
