Selection of a fragment to duplicate in the drawing is done by the option:
Select Fragment to create its copy
Upon calling one of those options, the system asks you to specify just the placement of the fragment in the
drawing. In this case, the external variables will have the same values as the fragment being duplicated.
Fragment Parameters
The section “Basic Parameters” contains data about the fragment file. The
button can be used to open a window for selection of the fragment file.
In the field available for editing, the text with the reference to the fragment
file is written down. The reference can be full or relative. The second line
shows the full path on the hard disk through which the written reference is
functioning. The relative reference can be written manually or
automatically in the following form:
• ..\..\folder\file_name.grb – in this case, the record is
made relative to the file of the assembly drawing. The symbol ..\
denotes going along the folders by one level up with respect the
assembly file.
• file_name.grb – in this case, the reference uses
the drawings library connected to T-FLEX CAD.
It is recommended to use the relative references which operate in a more
flexible way and are not tied to a specific place on the hard disk. It allows a
user, for example, to move the assembly with all documents contained in it
from one place to another without any losses.
The section “Insert Fragment” allows a user to select the desired page of
the document being inserted as a fragment (parameter “Page”). This
parameter is not available if there is only one page in the fragment. Also, in
the drop down list “Fixing” found in this section, the attachment approach
is specified: either by fixing points or by fixing vector.
The section “Fragment Parameters” contains different parameters of the fragment insertion:
Scale. Defines the scale of the fragment being inserted. This is used only when inserting fragments by fixing
vectors.
Rotation Angle. Defines the angle of the fragment rotation. This is used only when inserting fragments by
fixing vectors.
Scale line thickness. This parameter specifies whether to apply the assigned scale to the fragment lines
thickness. This is used only when inserting fragments by fixing vectors.
Symmetry About Fixing Vector. When set, the fragment image will be mirrored about the fixing vector.
This is used only when inserting fragments by fixing vectors.
Always regenerate 3D model. With this flag set, the 3D model of the fragment will be automatically
regenerated upon changes to the 2D fragment parameters.
Constant Fragment (Symbol). Setting this parameter makes the inserted fragment saved in the assembly
document as a picture. This allows speeding up the work with the assembly since now there is no necessity
to resort to external files. The fragment file is not read when opening the assembly. Owing to that, the
fragment can be displayed in the assembly even in case its source file is absent. However, since this is a
