As starter a cylinder with the variables 'HUB' for length and 'D' for diameter is used.

Expand the table in PARTdesigner:

Columns for alternative measurement: 'HUB2D' and 'XHUB'

Adjust the length of the cylinder.

For the length 'HUB' had been used by default.

Now in the input field Width, do not use the entry 'HUB' in the usual way, but with the following condition:

IF HUB2D = 0 THEN HUB ELSE XHUB ENDIF

Field entry with IF condition

If 'HUB2D' equals '0' (this is the default state), then the variable 'HUB' is used.

When activating the option Optimize drawing view on paper size, 'HUB2D' is set to a value unequal '0'. It is for this reason why the variable may not have a fixed value, but has to be stated as value range variable.

However, if HUB2D is unequal to '0', then 'XHUB' is used for the calculation of Width.

For the Height use 'D/2'.

Set the connection points. These may also be used for automatic dimensioning.

Note Make sure that all features,which are related to "HUB2D", also use a corresponding IF condition. Otherwise, a connection point which is normally located on a "Reference plane" is suddenly floating around as soon as the shortened view is turned on. IF HUB2D = 0 THEN HUB ELSE XHUB ENDIF Shortened view

For the cylinder project, set following entries under PARTproject -> Edit project -> tabbed page General -> section Alternative 2D size:

Alternative 2D size

This entry effects,

Optionally, you may set the automatic dimensioning. The displayed measure should not change when turning on the shortened view! Therefore, no IF condition is used for Text, neither {AUTOMATIC}, but '{HUB}'.

A detailed description of automatic dimensioning can be found under Section 5.10, “Specify automatically created dimensionings (notations) for 3D view and 2D derivation ”.

In order to visualize the Shortened view, add a sketch with a "cosmetic drawing" on the same plane as the main sketch (in this example plane XY).

For the curved line, use the function Arc through 3 points on circle.

For the positioning of the points, use the variable for the shortened hub ("XHUB").

XHUB/2

Positioning the points along the help line

In order for the help lines to only be visible with activated option Optimize drawing view on paper size, use the function Delete element with condition with the following condition:

HUB2D = 0

'HUB2D=0' is according to the default setting. In this case it shall be deleted. Only if the value of variable 'HUB2D' is unequal to '0', the sketch shall not be deleted, meaning the cosmetic drawing shall be visible.

Condition for cosmetic drawing

Result:

Note Testing the function Optimize drawing view on paper size (Shortened view) only works in PARTdataManager, not in PARTdesigner.

Now the cylinder is used in an assembly. In this example a vastly simplified configuration consisting of one cylinder and two blocks is used.
