In response to a pm I had I thought I'd put this little tutorial on here for anyone else that's interested -
(sorry the images are very faint - when I export them form bmp to jpg they go that way :x )
I was asked to show how I'd create a "swagged" curtain - I've only done it as a surface mesh - but you could turn it into a solid easily by using the m2s routine...
The first step is to create the curves for the top, middle and bottom of the curtain. I used a polyline and then splines them. For the sake of speed I simply created one poly and then copied it down twice and scaled. This creates "even crves in the curtain - if you want the curtains to be a bit more "messy" then create a different polyline for each...
Once the three polylines are created and positioned correctly, then you need to join the ends to make the vertical edges of the curtain. I've used a straight line for one edge and an arc for the edge representing the front edge of the swag. You should end up with a shape similar to the picture below...

Now you need to set the surftab1 and surftab2 variables to a value that gives a smooth mesh - the higher the number the smoother mesh - in this instance I used a value of 50 for each.
Using the edgesurf command I clicked on lines 1, 2, 3 and 4 in order and a mesh was produced as shown in the picture below...

I then moved that mesh out of the way (otherwise you won't be able to click on line 4). I adjusted the surftab2 variable to 13 (so that the vertical distance in the mesh looked the same as before) and repeated the edgesurf command, this time clicking on lines 4, 5, 6 and 7 in order. This gave me the picture below...

To create the tieback I moved the second mesh into place under the first and deleated the lines 1, 2, 3, 5, 6, 7 - leaving line 4. Looking in plan I drew a polyline around line 4 and splined it. I then copied the polyline down, scale it up a bit and rotated it to suit the size of the swag. Using the end point of line 4 I moved the 2 lines over to the meshes as shown on the picture below...

I then used the rulesurf command to create the tieback by clicking on the two lines. The curtain should look like the picture shown below...

It's then simply a case of erasing the 2 polylines and mirroring the meshes to get the picture shown below...

Hope this was of interest to you
All the best
