Reference Axis of the Shape
In the shape properties, you can assign so-called reference points or axes to a shape, which first are identical with the insertion axis of the component part after insertion.
This allows you to force dimensioning on a pre-defined reference to relate e.g. all important hole dimensions symmetrically to the center axis or to Upper Edge Steel for plateform girders. In overviews, you will also get the most important dimensions of the construction directly by means of these reference points. Since these reference points can be modified later, you can for example insert a shape on its center line in the grid, dimensioning, however, can nevertheless be related to the upper edge of the shape.
| Setting | Description |
|---|---|
| Reference Axis (1) |
The insertion axis of the shape or an explicitly assigned reference axis in the 3D model (A) |
| Reference Point (2) |
System Points of Construction
The system points here are the theoretical intersection points between the center axes of two connected shapes.
A logical link has to exist between these component parts, which is the case in most construction situations (such a link is for example also created by an intersection at welded-in diagonals of a truss). When a logical link doesn’t exist, you can define dependence later via manual link (please also refer to Dimensioning Areas/Assignment).
