The following description relates to the first two techniques of inserting a fragment into a drawing. The third
technique is described in the dedicated section “«Top-Down» Design”.
Enter the command “FR:Create Fragment” for inserting a fragment into an assembly drawing:
Keyboard Textual Menu Icon
“Draw|Fragment”
The following options will appear in the automenu:
Select File
Create new Fragment in Assembly Context
Extract Fragment Drawing
Set Fragment parameters
Repeat previous Fragment (accessible upon a repeated call
to the command)
Select Fragment to create its copy
Execute Edit Fragment command
Exit command
The controls for customizing parameters of the fragment will appear in the properties window. They are put
into several sections, their number and structure depend on the fragment creation approach. The sections of
the properties window allow selecting the file of the fragment being inserted, a way of attaching the
fragment, specifying external variables of the fragment, etc.
Before selecting the fragment file the dialog in the properties window contains only three sections:
“Basic parameters”, “Fragment parameters”, “Options”. The values of the parameters, defined
in the properties window before file selection, are automatically stored as default values for all
subsequently inserted fragments.
The first step when inserting the fragment is the selection of the file of a fragment. The dialog window for
selecting a file can be called with the help of the option or by pressing the button in the section
“Basic parameters” of the command's properties window. In the window for file selection it is necessary to
indicate the document file of the fragment. After selecting the file, a dynamic image of the inserted fragment
attached to the cursor will appear in the drawing window. The contents of the automenu will be changed.
The new state of the automenu will depend on the fragment attachment approach specified in the properties
window: by fixing points or by fixing vector.
The fragment attachment approach is specified in the section “Insert Fragment”, with the help of the
parameter “Fixing”. In case the fragment is attached by the fixing vector, the required fixing vector can be
chosen from the drop down list of this parameter. The required page of the fragment document can be
selected here as well (in case of multi-page document).
In the section “Fragment parameters” of the command dialog it is possible to specify various settings for
fragment insertion. A detailed description of these parameters is presented in the section “Fragment
parameters”.
