"It has always been like this. It would be trivial to write a plugin that saves the file behind Rhino's back, so when the eval expires, non-core plugins will no longer be allowed. If people want to use our software for longer than 90 days, they…"

Rhio evaluation will no longer run third-party plug-ins?

As I understand it this means that students cannot use the free version of Rhino 5 to access grasshopper after the evaluation period of 90 days expires.I have never experienced this issue before.So I just wanted to know if it is something new or it has always been like that?See More

"Hi Jesper, it's not technically clipping planes but it's the front and back limits of the depth buffer. You need to inform Rhino that you are going to draw objects in a specific location before the real drawing starts, so Rhino can figure…"

ClippingPlane Problem

HiMy problem is that when i display some lines in the DrawViewportWires method, they disappear when i zoom closer to them.I tried to use the args.Display.Viewport.SetClippingPlanes(boundingBox);but it does not help.If i bake this boundingBox i have no problem to see the lines at all time. But obviously I don't want this box to be shown.What am I doing wrong?public override void DrawViewportWires(IGH_PreviewArgs args) {for (int i = 0; i < lines.Count; i++) { if (!this.Attributes.Selected) {…See More

Changing preview color of breps

HiI use the following code to change change preview color of some geometry i create with a custom component.It works if I only have one input for the first input parameter in the component.However if I have multiple inputs only the first output geometry will change color and the rest will only be displayed as wireframe.How can i solve this? List<Brep> supportGeometry = new List<Brep>();protected override void RegisterInputParams(GH_Component.GH_InputParamManager pManager) {…See More

Simple Data Types problem

Hihas anyone managed to use thir own custom class as an output parameter to a GH component? I have a node class (see attached) that inherit from GH_Goo<Point3d>Next I have a custom component named CustomClass that takes a point and outputs a nodeLast i have a custom component named NodeTest that takes a node and output a point and the property  named connections. However my problem is that I cannot use the output of the CustomClass directly as input to a ordinary pointComponent The error…See More

how to make a digital model of a twisted cylinder

I'm currenty doing a study project where I bend/twist a cylinder. see images below

Anyone who have an idea how to construct this geometry.

Its simply a cylinder where you grab two opposite sides and rotate one of the sides to the desired angle.
In the images this is approximately 270 degrees
