Promote Element by Reference Attachment

Hi All,

I am new to GC and am currently exploring the possibilities; however I seem to have come to a roadblock in terms of the 'Promote Element' function. I need to be able to promote a complex element from a polyline contained within an attached reference file. I have chosen the promote mode 'by reference', to avoid having 1000's of point nodes being created at each vertex of the selected polyline (which slows my system down drastically, similar to this issue observed by another user).

The problem is that every time I replay transactions, the polyline node loses the memory allocation for the original element. Is there an alternative workflow that captures the original input element permanently? In order to go back and reallocate these nodes is quite time consuming, especially once this effect is multiplied across many input elements and GC modelers for each session.

My current workflow is utilising a 'Reference Attachment' node, then Promoting the individual elements within the attached file. I am thinking that this issue of memory loss through replay could be avoided entirely if the polyline node 'By Element' option was modified to be able to take an input from the 'Reference Attachment' node, then specify the Element ID under 'Element Path', similar to the attached workflow below:

Is this a feature that we could get implemented? Or are there better methods to achieve the same result? This would greatly improve our productivity in the workflows we are exploring for linear infrastructure; where the control lines are output by the track team (using OpenRail) in separate dgn files, and contain very large number of vertices.

Thanks in advance,

Edward
