Component Interface in Assembly mode of proEngineer
Here's a small tutorial on how to use the component interface in assy.mode in proE....for creo users it;s directly present...but for proEngineer WF5.0 and below users..Insert->Component Interface..
Component Interface is mainly used in order to cut-short the time involved in assembling components which are easy to assemble..for example a bolt and a nut to be assembled to a pulley...they all have same constraints..2 -Axes,Surfaces..So It 'd be boring and sometimes time consuming if we keep on specifying the constraints each and every time in a large assembly..for ex. An Engine..,So in order to make it much faster,We make use of the component interface...
