Supported on surfaces Positioning of repeated standard parts along a direction. It may be an edge. The following classification has been established based on the support. spacing between each other or total spacing between the first and the last ones in the parameters tab (two out of the three ones have to be selected). Enter the values of the selected parameters. selecting any point in the standard part and any other point in the support. Position it in its final position using snap. etc.2 Standard parts p ositioning Standard parts positioning depends on supporting geometry on which they are to be located.

Approach it to the support by means of the snap option.AIRBUS INDUSTRIE ASSEMBLIES APC002 7.0 position. Select the type of parameters desired to provide. • • • Along a direction. the number of standard parts. constrains or compass. The following is the process to be followed: • • • • Locate the standard part in the tree in the traditional manner. Select option fast multinstantiation definition and the following window opens up: • • • • Select the standard part as element to instantiate. AIRBUS INDUSTRIE ASSEMBLIES Multinstantiation Direction First standard part positioning APC002 Standard parts positioned according to a direction Positioning of standard parts supported on flat surfaces. Dealing with flat surfaces. there are two positioning alternatives. depending on whether patterns exist or not. Process is as follows if there are preset patterns: • Position the first standard part in the same manner as in the above paragraph (snap. (It is assumed a pattern has been created for each different type of standard part). Issue: A Date: Jan 2001 Page 22 of 31 . constrains or compass) located in the feature (hole) origin for the pattern. • Finally.

First of all it is necessary to have the hole feature (in addition to the positioning point) created on the support in each location the standard part is to be positioned. • • • Perform a multi-instantiation of as many repeated standard parts as necessary in any direction. selecting one point in the standard part and another one in the support. The following is the process to be followed: • After the standard part to be positioned is located in the tree structure. Note: If the surface was ruled. standard parts are positioned one by one using constraints.

Repeat the process for each standard part. Move to the coincidence option and select the hole centre line and the standard part centre line for each standard part and with the same option. select the standard part bearing surface and the support point.
