Fitting Engagement Distance

This has been in my drafts way to long. I only allowed myself to publish new posts if there is one ready to go in my drafts. Even though I am not back to normal I feel this might help me move towards normality even if I might never get there again.

Can fittings have both male/female connections and different engagement distance?

My friend asking this was referring to elements like bushings, and reducers as in the image bellow where the right side connection can fit 2 sizes, one inside (female) and one outside (male). These will need different engagement distances as well.

3 connections on same fitting.
Library or stand alone?

There is no gender on the fittings; they are all connected by points and axes but how you author it depends on what you intend to do with the file. Is this for an ipart to be published to Content Center, or is it a standalone library file?

More than likely this will be used in content center but if this is a standalone library then you need to author this in a weird way with 3 connections instead of 2. When you place the fitting press Spacebar until it shows the correct position.

While this is possible I think most of you will need this in Content Center. For that you will create two identical shape members with different connections.

Even though these members will have identical part number, stock number and whatever fields you use to identify this, the filename needs to be unique. This is one rare occasion when I allow filename to be different than the part number.

How do we create a dynamic engagement distance? You create an offset work plane and you control the offset value from the ipart table.

In the author fitting window choose Engagement, To Plane, Point and choose our plane.
