To avoid unwanted openings for powder outlet in hallow parts.
This can be done with respect to a plane inserted at desired location. The planes can be inserted either
parallel to or at an inclination to the conventional planes (top, front and
When there are no flat surfaces in the geometry, it is easier to split the parts with respect to planes. The ways of inserting planes are described below:
Before inserting the plane, a sketch must be made such that it contains the line in the existing plane, through which the new plane passes through. Now the plane can be inserted by using the At Angle option and selecting the plane and the sketch to complete the plane definition.
The next step would be to shell the parts and introduce fastening features like Lip-groove that would help in effective fastening during assembly.
It must be remembered that during the Shell operation, the wall thickness should be good enough to accommodate the Lip-groove fastening.
Select the face which needs to be the
opening and select the Shell option from Features
Now that both the parts are shelled, next step would be to introduce fastening features to join them together after getting printed.
For these cases, the ideal fastening feature would be Lip-groove. With proper selection of wall thickness one can achieve a very good mating surface between the parts.Lip Groove fastener
Select the two solid bodies and omit the direction of lip/groove.
The green surface represents the Face on which the groove is to be created and the blue dotted-line represents the inner edge for groove to remove the material
Make similar selection on the other part. This results in the following parts with lip and groove fastening
