To make a panel, you draw a closed region consisting of two or more NURBS curves. The curves must satisfy the following requirements:
The curves must form a closed region. In other words, the last control vertex of one curve must be in the same position as the first control vertex of the next curve.
They also must be coplanar, which means the curves are all drawn in a plane.
You need at least two curves to create a panel.
Remember, each curve must touch the end of the previous curve.
You can use Snap to Curve to verify that your curves are attached exactly at their endpoints.
How to make a panel
1 Select the curves that represent the portion of the garment you want to designate a panel (selection order is unimportant).
2 Select Cloth > Create Panel. A panel node is created.
What if you get error messages?
In order to create a panel or a garment, your curve must be planar, and they must make a closed loop. If not, you'll get an error message. Here are some tips to help if you get an error message when you try to create a panel.
You can also get this error message if you have selected curves that are on top of each other. This can happen if you have duplicated an extra curve. Check the Outliner to make sure you don't have extra curves.
Curves must be coplanar
If you get the message Error: Curves must be coplanar when you try to create a panel, it means that the curves are not on the same 2D plane.
You can avoid this error by drawing your curves in an orthogonal view and turning on snap to view plane. Make sure you don't accidentally rotate your curves.
