Example 5: Multiple Sweep Directions

Below is another example of using different directions of sweeping for the same model. The model is a cube pierced by several cylindrical rods. The rods do not intersect each other.

Proposed sections

	FIDESYS> webcut volume all with plane yplane offset 20
	FIDESYS> webcut volume all with plane yplane offset -20 FIDESYS>imprint all FIDESYS>merge all

All volumes obtained by cutting the original model are now suitable for sweeping in the one source - one target manner. However, for the cube components, the initial and final surfaces must be specified explicitly:

Table 2. - Specifying the mesh construction scheme.

FIDESYS>volume 8 scheme Sweep source surface 94 target surface 90 rotate off

FIDESYS>volume 10 scheme sweep source surface 71 target surface 73 rotate off

FIDESYS>volume 12 scheme Sweep source surface 97 target surface 100 rotate off

FIDESYS>volume all size 2

FIDESYS>mesh volume all

Resulting mesh

For the model under consideration, different directions of sweeping are possible, since the superimposed surfaces are simultaneously connecting surfaces. The constructed mesh consists of elements of size 2, Fig.
