The Orientation of attachment points in the PARTdesigner and thus the Positioning settings ( rotation [Rotation] / translation with min-max [Min] values) [Max] should be special attention should be paid to the creation of an assembly as simple as possible and to avoid any problems in CAD systems. avoid.

Example:

The The following example figure shows a lever with a starting position from 0°. The lever can be rotated from -90° to +90°.

Lever with starting position 0° and rotation range from -90° to +90°

Problem	The standard procedure leads to a incorrect starting position (default position) of the Component.
Goal	Correction of the starting position
Solution a)	Manipulation in the Configurator in the Rule Properties [Rule properties] dialog
Solution b)	Adjusting the orientation of the Attachment point in the sketch Note Solution b) is definitely to be given preference .

That The following example shows the problem on the basis of the Standard procedure (solution a):

Initial situation in the Variable manager [Variable Manager] with value range dialog in of the table.

Variable Manager: Definition of rotation - initial value 0° and value range from -90° to +90°

Initial situation in the Sketch: The attachment point to the Component was set with an angle of 0° by default.

After rotation and min-max values have been set by default, results in an incorrect starting position of the lever (desired is default position to the top).

	Note
	All settings in the rule's Properties [Rule properties] dialog box are based on the orientation of the attachment point so that default settings are not desired results.

The default return value of "PARTDUMMY@ROTATION" is 0°

The quick solution would now be a correction of the rotation with "-90".

-90+PARTDUMMY@ROTATION

	Note
	A negative value for manipulation should be should be avoided at all costs so that there are no problems on the part of the CAD system. appear.

One justifiable, alternative approach looks like this:

270-PARTDUMMY@ROTATION

This however, it now also requires an adjustment of the min-max values. There PARTDUMMY@ROTATION values from -90 to +90 , the min-max values are 180 and 360.

Min = 270-90 = 180
Max = 270+90 = 360

Correct adjustment of rotation and Min-Max Values

A lot simpler and without the risk of incorrect settings is the solution b).

Correct the angle of the attachment point (here in the example to the value 90).

Now , you get the desired one with default settings in the rule's Properties [Rule properties] dialog box Starting position of the lever.

	Note
	All explanations in this example apply analogously also for translation.
