I am quiet new to Grasshopper and there are two issues which annoy me, as I can´t find out what I am doing wrong.
First: Whenever I save my file and reopen it, it is completely empty. The referenced mesh is not in Rhino ( it was an OBJ I imported). But the Nodetree still exsists.
Second: I thought I could use the node tree and just replace the mesh with another OBJ and It could work. It doesn´t. I still get the warning " A referenced mehs could not be found in the Rhino Document". And also the Fit line Node is all red “you need at least two points”. My object is closed. no open faces.
What am I missing? This is very importand for me, as I am doing my Uni project with it and I need to show it next week.
sry for the confusion. I am usually using Blender 3D and wasn’t aware that the terminology could be different in Rhino/Grasshopper.
By re-opening I mean both, the Rhino file and the Grasshopper file. I saved my changes closed it. After opening the file the next day, Rhino was empty, like the OBJ which was imported the previous day wasn’t there.
With node tree I mean the structure you build inside Grasshopper. The components.
The error I get is actually at the very beginning. The Mesh component gives the warning (yellow) “A referenced mesh could not be found in the Rhino Document” and the Fit line component gives a warning (red) “you need at least two points”. Hope this helps.Pls see the attached screenshots
