The implicit profile is a sketch and as such
supports the creation of associative sketch elements over multi-cell
surfaces. When creating the swept surface, the implicit profile allows you to impose a
constraint over a multi-cell surface that is use as a construction element. When designing the profile to be swept, keep
in mind that the constraints imposed on the sketched profile affect the
resulting swept surface. For instance, with the apparently similar sketch
(only its construction differs, but there is a coincidence constraint
between the sketch extremity and the point on the guiding curve) you can
obtain the following results:
Sketch based on the point (no coincidence
constraint, but a geometric superimposition)
Sketch based on the point as the
intersection of the sketch and the guiding curve
Sketch based on projection of the point in
3D
Constraints
It is best to use angle
constraints rather than tangency or
perpendicularity constraints, to avoid changes in the sketch orientation as
it is swept along the guiding curve. In some cases, with tangency or
perpendicularity constraints, the sketch may be inverted and lead to
unsatisfactory results.
Gaps
To avoid unsatisfactory surface quality such
as gaps between surfaces for example, you can perform one of the following:
Select a boundary on an
adjacent surface as a constraining element when creating the sketch.
The selection of the boundary allows a better
topological splitting, and therefore better quality for the created
surface.
Swept surface (blue) without selected boundary Swept surface (blue) with selected boundary
Impose more sections along
the guiding curve.
Decrease the
discretization step value to better define the sweeping along the guiding
curve.
