*Patch Creation - By 4 Points - you may create a patch out of points. For this, select 2 to 4 points as corner points of the patch. - The selection direction defines the orientation of the normals (clockwise produces normals in view direction).;*Patch Creation - By Raw Data - patches can be created from raw data contours. -You have to select at least four contours forming a closed area.;*Patch Creation - By Curves -surfaces can be created from edge curves. Parameterization type, smoothing factor and approximation orders can be set for edges being not in Bezier - 2 to 4 edges must be defined for carrying out the function ;*Patch Creation - By Patches -Any number of neighbored patches can be approximated by a single patch using this function.;*Patch Creation - Blend (Connecting Patch) - generates a blend patch between two curve segments or patch edges. - A blend patch matched into the interior of a patch can be created using the Offset Law;*Patch Creation - Face (Trimmed Patch) -Faces (trimmed patches) can be created with this function. -One or several curves (3D trim curves) are projected onto a patch (or face). ;-advantages: The original patch can be reproduced at any time. Patch and face are identical concerning their shape, they only differ from each other regarding their edges. The face edge curves can be created later. The face edge curves can have any shape, e. g. holes can be cut into a patch. - disadvantages : Faces can only be modified by global modelling. During modification the edges cannot be fixed. patch matchings possibly cannot be carried out exactly.;*Patch Creation - Surface of Revolution The rotation of a planar or 3D curve ( generator curve ) about an axis traces the shape of a surface of revolution. ;*Patch Creation - Barrel - creation of a barrel surface is used to create crowned surfaces;*Patch Modification – Point - by moving an arbitrary p
