Hi everyoneI earlier asked about _CreateSolid command in Grasshopper and got the reply that it isn't in the .SDK NET package (I'm not much of a programmer but what I've gathered it means that I cannot create solids with Grasshopper).Now the workaround I've been using is to bake each part that consists of 4 BReps and then run a macro in Rhino  wich completes the solid making process'_SelAll_Pause _CreateSolid_Enter_Pause_Hide (The hide is there so next part can be selected…See More

"You want to know the lowest control point or the lowest point in the curve? If it's the second one, use a bounding box and a box corners component."

Need a small help with getting specific point (lowest z value)

Hi, I'm currently working with a closed curve I have from intersection with an extruded circle and a curved surface. As a result I have a curve wich control points are several hunderds that define it, but I'm trying to pin out the point with the lowest Z value, sorting doesn't seem to work for me. Any suggestions?

"_CreateSolid is not exposed in the .Net or RhinoCommon SDKs therefore we cannot access them in a GH component. I have put in a request for this, hopefully it will show up in the next service release or update. Luis"

_CreateSolid in Grasshopper

Hi, can't find this in Grasshopper, I know of the solid union, that command doesn't work. What I'm trying to do is to create a solid from 4 surfaces. The _CreateSolid command in Rhino works but not the grasshopper solid union command.Anything I'm dooing wrong? Do I need to trim/untrim surfaces before joining them?And sorry for a basic question like this (I assume it is since I can't find another thread about it in a glance).See More
