1. Watch the videos
Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.
LoftingTransition between profiles, guide curve, start and end constraints, connectors.In French↗ SweepsMove a profile along a path and set the basic options.In French↗ Sweep ProfilesConnect the profile to the path and guide curves with the right relations.↗ Sweep Orientation and TwistFollow the path or keep the normal constant: the effect on the profile.↗
2. Key takeaways
A loft connects profiles; add guide curves when the shape between the profiles must be controlled.
Start and end constraints (normal to profile, tangency) set how the shape starts and ends.
Connectors fix a twisted loft by linking the right vertices between profiles.
For a sweep, sketch the path and guides before the profile, then connect them with pierce relations.
Tip
If a sweep fails, check the path first: a radius smaller than half the profile or a break in tangency is enough to block the feature.
