IPCB_Dimension

Overview

Dimension objects are used for dimensional details of a PCB board in either imperial or metric units and can be placed on any layer. To create an original Dimension objects, use the IPCB_OriginalDimension class which is used in P99SE and earlier versions.

Protel DXP introduced several new dimension styles - Linear, Angular, Radial, Leader, Datum, Baseline, Center, Linear Diameter and Radial Diameter objects

The IPCB_Dimension interface is the ancestor interface for IPCB_OriginalDimension, IPCB_LinearDImension, IPCB_AngularDimension, IPCB_RadialDimension, IPCB_LeaderDimension, IPCB_DatumDimension, IPCB_BaselineDimension, IPCB_CenterDimension, IPCB_LinearDiameterDimension, IPCB_RadialDiameterDimension interfaces.

Important Notes

The DimensionKind property determines the type a dimension object is.
A dimension object especially a baseline or a leader dimension has multiple reference points. The references (a reference consists of a record of an object along with its x and y coordinate point, an anchor and is a start or end marker). A reference point is either the start or end marker and the length of two reference points is the dimensional length.
