Merging Parts and Joining Lines (Lid and Base Parts)
Sometimes it is necessary to join components with others. You will need a witness line of approximately 2mm in order to cope with the tolerance variation of the joint. A popular technique is the use of a lap joint. This will result in an undercut which will make project costs higher but will enable you to join the pieces.
Create Quality Undercuts
An undercut is the feature that projects into or from the surface of the tool. This can sometimes prevent you from being able to separate the tool from your part. It is because of this that you should aim for an undercut with a depth less than 15mm. Whenever you create a design for one, you should keep in mind the draw ratio.
