When creating a fixing vector, in its parameters specify the layers of the drawing to be displayed in the
assembly. This allows, for example, inserting different views of the same part in an assembly.
If the 3D model exists in the document, then the fixing vector can be bound to a specific workplane. This
allows using 2D fragments in three-dimensional assemblies for defining the position of a three-dimensional
fragment in the space with respect to the final position of the fixing vector and the selected workplane. This
assembly creation technique is called “Layout”. Detailed information on this technique can be found in the
three-dimensional modeling manual, the chapter “3D Assemblies Creation”. This kind of relation allows
inserting a 3D fragment automatically when the respective 2D fragment is assembled. To enable this feature,
set the flag “Create 3D Fragments Automatically” in the command “SO: Set System Options”, the tab
“Fragments”.
Fixing Vector defined by two points
When inserting a fragment with such fixing vector, the position of
the first point (the vector start) will be defining the fragment
placement position within the assembly drawing, while the second
point position (the vector end) - rotation of the fragment in the
assembly.
To create such vector, subsequently select two nodes by clicking
. Once the second node is selected, a dialog box appears in the
screen. You can enter a comment for the fixing vector in this
dialog. The comment will help selecting the fixing vector when
inserting the fragment into an assembly drawing.
The attribute “Use as default Fixing Vector for Fragment
insertion” defines what fixing vector will be offered by default
when inserting the fragment into an assembly drawing. Although
multiple fixing vectors are allowed in a fragment drawing, only one
fixing vector can be defined as the default.
The group “Link to Layers” serves for managing display of the
drawing layers upon assembling. The parameters in the group
affect only the display of 2D fragment elements. They do not affect
visibility of 3D fragments placed on the respective layers.
Layer list. This pane contains the list of all layers existing in the
drawing. Here you can mark those that will be displayed when
assembling the document as a fragment using this particular fixing
vector.
On the diagram below, highligted are the fixing vector and the drawing elements to be carried over to the
assembly drawing. Those elements are assigned a new layer. Exactly this layer must be check marked in the
fixing vector parameters.
After that, when assembling these drawing as a fragment, only the check marked layer will be displayed in
the assembly drawing, and, therefore, only the elements that lie in this layer will be displayed.
