Implicit Profile

The implicit profile is a sketch and as such supports the creation of associative sketch elements over multi-cell surfaces. This allows, when creating the swept surface, 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

Similarly, 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:

1. 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.

2. Impose more sections along the guiding curve.
3. Decrease the discretization step value to better define the sweeping along the guiding curve.
