General Notes on Referencing

Marking of referenced parts in the ICN

Referenced parts are marked with specific symbols in the Information + Communication Navigator (ICN). In the part structure, an "R" symbol is directly attached to the part symbol. The meaning of the different colours are as follows:

	Externally referenced parts
	Internally referenced part
	Referenced part, read-only
	Non-updated referenced part
	Non-updated referenced part, read-only

For externally referenced parts, the text (referenced) is shown, in the Geometric type row of the Properties window of the ICN.

The Fitting Coordinate System of referenced parts

A so-called Fitting coordinate system (short: Fitting CS) is automatically assigned to 3-D parts when they are referenced, and entered into the feature log.

If a part has no Fitting CS yet at the moment of referencing, the following applies:

If a part is referenced directly upon its creation (which is, for example, possible for Solid primitives), its Fitting CS will be the current local coordinate system. If no local coordinate system is defined, the Fitting CS will be determined by the points (0,0,0), (1,0,0) and (0,1,0).
If a part is inserted, and referenced directly after its insertion, its coordinate system will be the World coordinate system.
If a part is inserted, and further parts are added to the drawing, and for one of these parts a local coordinate system drawing is created, this local coordinate system will become the Fitting coordinate system when the first part is referenced. This rule also applies if the referencing of the first part is removed and the part is then re-referenced.

Example: (1) Insertion of a referenced part, (2) Creation of further parts and definition of a local coordinate system, (3) Breaking up referencing and re-referencing of part

If a Fitting CS already exists during referencing, the following message appears:

By activating of the desired option and confirming with OK you can either

keep the existing Fitting CS, or
replace the existing Fitting CS with the active CS.

Please also read the notes on the Fitting CS in the Coordinate Systems topic in the HiCAD Basics Help chapter.

Handling of article masters for referenced parts and assemblies

If a main assembly is referenced and has an article master which is different from the article master of the drawing, no automatic corrections will be applied to the article master assignment and/or the HELiOS links of the main assembly.

If the main part has an article master which is different from the article master of the drawing, no document master links will be checked or corrected (this also applies to the Management + BIM functions). If the main part is also referenced, no article master links will be checked or corrected either (this also applies to the Management + BIM functions).
