LwCad for LightWave
How to Make a Patch with splines?

So I went through all the lightwave cad 5 videos a few times and I still can't figure out how to make a simple patch. Lofting was easy enough but I feel it doesn't give quite the amount of control I need. In one video I see a grid of splines already made ( I guess with the line tool?) and then I see patches begin drawn easily. . . I don't understand how the splines were connected in order to make a series of patches that are attached together. Can I get more of a hint on this? Welding doesn't work and drawing the splines on top of each other doesn't work with the patch tool either, what am I missing? Thanks.

Spline end points must be connected or just touching.
Then just select three or four those splines with Patch tool.

If still problem, please send me the object.

Thanks Viktor! I got it figured out. How do you recommend I join two patches together. I can get two four sided patches to join together using the join command but they only join at the corners I can never get isoparms in the middle of a patch to join to other isoparms on a separate patch unless I weld them together. Not sure if that is stable or not.
