While editing a Group, you can’t create an Array.  There are two workarounds:

  1. Make the array ‘outside the group’ and then Add it to the Group.  This requires you to Finish Group, make Array, Edit Group, Add… etc
  2. You could use a line based Component as an array ‘guide’ to provide you with the intervals you need, and then Copy Multiple.  If you are in a Detail Group, use a Detail Component, if you are in a Model Group, use a Generic Model.

Here are some links to download my array guide components
These components have two instance properties – one to control the size of the ‘tick’, and one to control how many elements / divisions are in the array.

There is huge post on content (family) creation over at this link.  I have provided a few useful excerpts below:

A handy list of relevant Agencies / Organizations:

Nice tip on formulaic materials:
How do you parametrically change a material parameter in a family if the material itself depends on factors outside of each type designation? After all, it’s impossible to control materials through formulas. Our approach (when the number of ‘stacked’ geometry instances is few) is to model separate pieces of geometry, apply their unique material and then control their on/off visibility through parameters.

How to provide error messages to the family user:
One solution to this perplexing problem is to include 3D text displaying a message to the user when a non-existent configuration is selected.
