Stitch dialog box (Part environment)

Stitches surfaces together to form a quilt or solid. Surface edges must be adjacent to stitch successfully. The stitch command has a tolerance control that provides an upper limit and helps Autodesk Inventor determine the proper edges to be used for stitching.

Ribbon: 3D Model tab Surface panel Stitch

Selects parametric surfaces to stitch together into a quilt or solid body. Also used to analyze whether surfaces are suitable for stitching. Creates a stitch feature that can be edited later.
Stitch tab	Surfaces. Selects individual or all surfaces to stitch together into a quilt or analyze. Surfaces are highlighted in the graphics window as they are selected. Maximum Tolerance. Select or enter a value for the maximum allowable tolerance between free edges. Find Remaining Free Edges. Displays the free edges that remain after stitching and the maximum gap between them. Select a row item and right-click on it to display the context menu. Select Find in Window, to zoom in on the edge. Select Set as Tolerance, to quickly change the maximum tolerance used in stitching. Free edge pairs display the value of the maximum gap between them. Free edge pairs which partially exceed the maximum tolerance, display the minimum gap in Red (meaning that the gap is within tolerance but not fixed). Free edges without pairs display no gap value. Maintain as surface. If not selected, a stitched surface with a valid closed volume is solidified. If selected, the stitched surface remains a surface.
Analyze tab	Analyzes selected surfaces and marks surface edges with condition to indicate suitability for stitching into a quilt. Identifies surfaces that have gaps or tolerance errors. Show Edge Conditions. When checked, this option identifies surface edges by color to show results of analysis. Black edges are stitched to an adjacent surface. Red edges are free edges on a surface, and are not stitched to an adjacent surface. Show Near Tangent. When checked, this option shows near tangent conditions. Magenta edges have some discontinuity to the adjacent surface (are nearly tangent). These edges can cause failures in subsequent design operations such as creating a shell. Note: This option has an impact on performance.
Maintain as surface	Select to maintain closed volume as surfaces. If not selected, a closed volume that results from the stitch operation becomes a solid.
Apply	Stitches selected surfaces into a quilt.
