Few days ago started using new version of Live Connection 2.0 and faced a problem: in previous version I draw a Curve and connected it to input "Curve" to create a slab using Grasshopper node . And it worked.
But in new version there is a "Polygon" input, not "Curve". When I create a Curve in Rhino and connect it, a problem appears - "Invalid Polygon value. Outline Curve is self-intersecting". I tried many types of Curves, but Node didn`t accept them. How simple rectangle can be self-intersecting? Then I tried to create a polygon in Rhino and connect it to input. Node said that my polygon was not in horizontal plane. But IT WAS. I tried some types of polygons in horizontal and vertical plane, but it didn`t work. It is very strange, because I can create any other elements without problems.
Has anyone run into the same problem?

The original issue reported here (error #245138), should be fixed in the AC22 version of the Connection tool already, and we plan to fix it in the next update of the AC21 version as well.
The issue actually only happens if the unit in Rhino is set to milimeters instead of meters. If your Rhino unit is set to meters, it should work fine. Until the fix is released for the ARCHICAD 21 version you can evade the issue like this.

Have you tried with plain Rhino for Mac, WIP-version seems to be old already? I believe RhinoWIP should have warned you about it.

You may have also noticed we recently published the 5.4 update to Rhino 5 for Mac 3.8k. If you’re looking for Grasshopper or PanelingTools, that’s where you will find them.

I started new project in CM for small objects. Probably due to accuracy Rhino returns selfintersection.
Try M for Large objects should be fine.

Yes, there is a known issue, that our tolerance was pretty tiny when it came to checking whether something was planar, so that might have been an issue.
There are also a few other issues in that version as well, so you might want to try the preview version of build 6000. You can download the ARCHICAD update from here, and the corresponding Add-on from here. Note that these update packages are not final, so there might still be some major issues in them. You can see the conversation about them here.

True connection is greate and it was improved very much over last year. Hope you will keep it up. There is still a lot to do.

By the way I made request to make part of code open source like most of GH plugins. Do you think it's possible ?
