Work features are abstract construction geometry used when geometry is insufficient for creating and positioning new features. To fix position and shape, constrain features to work features. Environments that use work features Work features are available in these environments: Work features in parts are parametrically attached to a feature. UCS can …

The perpendicular constraint causes selected lines, curves, or ellipse axes to lie at 90 degrees to one another. On the ribbon, click Sketch tab  Constrain panel  Perpendicular Constraint  . Click the first line, curve, or ellipse axis. Click the second line, curve, or ellipse axis. Continue to place perpendicular constraints, or do one of …

The parallel constraint causes selected lines or ellipse axes to lie parallel to one another. In a 3D sketch, the parallel constraint is parallel to x, y, or z part axes unless you manually constrain to selected geometry. On the ribbon, click Sketch tab  Constrain panel  Parallel Constraint  . Click the first line or …

The fix constraint fixes points and curves in position relative to the sketch coordinate system. If you move or rotate the sketch coordinate system, fixed curves or points move with it. On the ribbon, click Sketch tab  Constrain panel  Fix  . Click a curve, center point, midpoint, or point. Continue to click curves or …
