• Select a location for the seed point such that the fixed warp fiber or the fixed weft fiber does not enter and exit the ply boundary multiple times.

• Draping over inner loops is supported. However, you may not achieve good results in the following cases:

◦ The ply contains a large, slightly non-planar or twisted inner loop.

◦ The ply contains a small, extremely non-planar or twisted inner loop.

• Avoid draping a ply around a continuous shape, such as a cylindrical surface. You can drape only up to 350° around such shapes.

• Align the draping direction parallel or perpendicular to the areas of high curvature because when you drape a ply at an angle across an area of high curvature, such as 45° to an upstand or U-section, it may produce high shear deformations. You can align the draping direction parallel or perpendicular to the areas of high curvature.

• When a ply drops over a large stack of underlying plies or a thick core, then it can result in high shear deformations. You can use a larger step length value to reduce the modelled shear deformations.
