Command: Edit|Create Part Icon: Description: Creates a new part by selecting two points in the CAD view to fix the two ends of the center
line of the new object. Conditions: The CAD view must be in the basic object selection mode .
Procedure
1. Select the 'Create Part' command. The status bar has the prompt 'Create Part > Select First Point >
Select Point'. The command dialog is as follows:
Fig: Command Dialog: Create Part > Select First Point > Select Point
2. The command prompts for the selection of a 3D point (see: Selecting a 3D Point )
to fix the first end of
the new object's center line. Having selected the point (by either typing a value into the 'Point' edit box or
by selecting the point with the mouse) the new object is activated
with the first end of the center line at
the first selected point. The command now prompts for the selection of the second end point of the center
line (Status bar shows: Create Part > Relocate Part End > Select Second Point > Select Point). The object
is actively stretched from the first selected point to the current cursor position, ready to drop the second
end of the object at the second selected point.

If the object is to be created in the horizontal XY plane the cursor plane should be set to the XY plane. If
the object is to have orientation in the Z direction one of the vertical cursor plane should be selected. The
static axis value can be altered at any time using the edit box.
When the new part is active (i.e. center line is rubber banding )
and number of useful snap tools become
available to help achieve the required orientation for the new part.
The command dialog/s have the following input fields:
a. Static Axis (value) - The 3D cursor position in the static axis of the cursor plane .
The 2D cursor
movement will continue in the cursor plane with the static axis value unless something forces it to change
(e.g. Snapping )
b. Active Plane (the active cursor plane) - the active palen is the cursor plane .
It can be altered at
any time from the toggle buttons on the 'View' tab of the taskbar.
c. Point (3D point input) - The 3D point selection can be made by typeing the value into the 'Point' edit
box. If the point is a relative point (i.e. relative to a datum) then the typed point is dependent on the
setting of the Datum combo box. If the datum is set to 'Absolute' then the typed point is interpreted to be
relative to the world origin. If the datum is 'Relative' then the point is taken as a relative point to the
datum point of the active object. In other words typing a value of '0,0,500' will select a point 500 above
the first point in the Z axis direction. It is possible for force the input to be a relative point irrespective of
the datum setting by typing an '@' in fron of the point. In other word typing '@0,0,500' is identical to the
typing the point with the relative datum setting.
d. Datum - The datum field is included for relative point selection only (i.e. second point selection). It can
be set to 'Absolute' or 'Relative' (as described in c.). When set to 'Relative' the current 3D position shown
in the 'Point' field in the relative position of the point to the datum point. If 'Absolute' the Point field is the
positio relative to the world origin. Typed points are accepted according to the 'Datum' setting (see c.).
e. Length - When rubber banding an active object the length of the object can be fixed by either typing
in a length or checking the 'Fixed Length' check box. This restricts the 3D cursor movement to the object
length. When objects are activated the length is normally fixed. Unchecking th 'Fixed Length' check box
liberates the 3D movement and allows the object length to be extended.
f. Fixed Length - Fixes the length of the active object (see e.).
