Pattern Repetition
A technique where different structural components can be linked together so as to produce similar topological layouts.
To achieve this goal, a master DSIZE card needs to be defined, followed by any number of slave DSIZE cards which reference the master. The master and slave components are related to each other through local coordinate systems, which are required, and through scaling factors, which are optional.
Other manufacturing constraints, such as minimum or maximum member size, can be applied to the master DSIZE card. These constraints will then automatically be applied to the slave DSIZE card(s) as described in the sections below.
- Create a master DTPG card.
- Apply other manufacturing constraints as needed.
- Define the local coordinate system associated to the master DTPG card.
- Create a slave DTPG card.
- Define the local coordinate systems associated to the slave DTPG card.
- Apply scaling factors as needed.
- Repeat steps 4-6 for any number of slave DTPG cards.
Local Coordinates Systems
- CAID
- Defines the anchor point for the local coordinates system.
- CFID
- Defines the direction of the X-axis.
- CSID
- Defines the XY plane and indicates the positive sense of the Y-axis.
- CTID
- Indicates the positive sense of the Z-axis.
