generative modeling for Rhino
Yes I am having the same problems. Works fine for a positive offset but doesn't like it when it is negative.
Jinge, can you post you VB Script, using curve.offset please.
I didn't visit this forum for quite a long time. I almost forget about it. I'm travelling and I don't have the script by my side now, I will try do find it later.
Can you have a look at the Offset curve command in GH 0.8.0007. It appears to be totally up the duff.
The component is totally unpredictable. Using the same method (a simple referenced rhino rectangle) some times it offsets in the positive direction, and other times in the negative direction (using the same offset value). Other times, it does't offset in one direction. I though it might be a tolerance or unit issue in the rhino file but it all appears to be fine. Frustrating!

Hopefully David is very nearly ready to release the next version.
What version of Grasshopper are you using? I'm on 0.8.0066 and it is working for me with your geometry. I know that for previous versions the offset curve component wasn't working properly.
I am using Rhino 4 and Grasshopper 0.9.0014. I tested your approach with Wires instead of edge and seems to work. This means that works better wires ...thanks for help
Ps. Is there any way I can do all wall at the same time or need to do each separately?
Yep - when you right click on the surface geometry component ('Brep wall_windows') select 'Set multiple surfaces' instead of 'set one surface'.
