Landing curves are defined when creating profile systems, seams, and reference curves by projection. When creating landing curves, use the following best practices. For more information, see Landing Curve Methods.

  • Avoid multi-lump (non-continuous) landing curves. For example, profiles crossing openings or openings cutting profiles are not valid.

  • Do not define landing curves that overlap or are collinear.

  • When placing profiles by projection, the default profile type depends on the selected sketching plane. This might not be the intended type. For example, when creating longitudinal profiles with a transverse sketch plane, the default type is Transverse. Check the type on the Properties dialog box, and modify it if needed.

  • When placing profiles or seams by projection, extend the landing curves beyond the expected plate boundary or surface edges. If the geometry of the surface changes, then the landing curves are long enough. The recommended extension is approximately 1 meter.

  • When placing profiles or seams by offset, do not use an offset value of zero.

  • When placing profiles or seams by projection that are to be bounded, extend the sketch curve past the boundaries in Sketch 2D and then set boundaries in 3D.
