I have some improtant advise about Creo 5.0 Freestyle I advise add the command [maintain shape to add line ]。I think this is very import for Freestyle。although it has the comand[add line],but it has many limitations when shapping。When I modeling the high curvature surface，add a line will greatly change current shape。I compared with the software 3dmax and Rhino，they all have this function。 Please value my advise about the function[maintain shape to add line]。 Another advise about Freestyle is to add [four windows],it will offer some convenient when have a reference picture。 Here some picture from me about Freestyle in Creo 4.0，but it has many many limitations when use Freestyle。
