Descriere
Instrumentul Dimension Link crează o legătură între geometria 3D și 1 sau mai multe Dimensiuni pe o Pagină. Legătura permite Dimensiunii să utilizeze valorile 3D actuale în locul valorilor proiectate 2D.
The TechDraw LinkDimension tool creates a link between 3D geometry and one or more existing projected Dimensions on a Page. This link allows the Dimension to use actual 3D values instead of 2D projected values.
The Link Dimension tool's most common use is in dimensioning isometric views in a ProjectionGroup. The projected length of an Edge in an isometric view will, of course, not necessarily equal the actual length of the Edge. In an orthogonal view the projected and actual lengths will be equal.
The link instructs the Dimension to compute it's value directly from the 3D geometry.
Cum se folosește
- Create an appropriate dimension on the drawing page using any of TechDraw LengthDimension, TechDraw HorizontalDimension, etc. This dimension will be in the right place on the Page, but will show the projected dimension value.
- Select the geometry in the 3D view, for example, an edge, that corresponds to the projected geometry of your dimension.
- There are several ways to invoke the tool:
- Press the
Link Dimension to 3D Geometry button.
- Select the TechDraw → Dimensions →
Link Dimension to 3D Geometry option from the menu.
- Press the
- A task panel opens.
- Select one or more Dimensions to be linked to the selected 3D geometry.
- Press OK.
The link operation changes the DateMeasureType property of the dimension from Projected to True.
Limitări
- Legăturile dimensionale sunt foarte sensibile la problema "Topological Naming". Se recomandă să conectați dimensiunile la unul din ultimii pași ai procesului dvs.
- Instrumentul Link nu vă împiedică să creați legături ilogice.
- În prezent, nu există nicio modalitate de rupere a unui link. Puteți redefini MeasureType înapoi la Projected și Dimensiunea va folosi valoarea proiectată în locul valorii efective.
Dimension objects are vulnerable to the "topological naming problem". See TechDraw LengthDimension for more information. It is recommended that linking dimensions be one of the last steps in your drawing process.
The link tool will not stop you from making illogical links, so you need to choose the correct edge from the 3D view when creating the link.
There is currently no way to break a link; you can change the DateMeasureType back to Projected so that the dimension will use the projected value instead of the linked value.
Note that if the Dimension to be linked is based on two vertices, you should select two vertices in the 3D view. Similarly if the Dimension is based on an edge, you should select an edge in the 3D view.
Script
Dimensiunile pot fi legate de geometria 3D folosind Python.

The TechDraw LinkDimension tool is not directly usable in macros, but changing the DateReferences 3D property can accomplish the same result.
