Does anyone change this in your template to create a layer and spatial index to improve performance?
If you do what are the pros and cons?
I believe by default C3D does not save an index.
John Mayo
Interesting question. We usually only resort to that if there are problems with an XREF'ed file. It usually takes longer to save (no suprise there). I've never tried it as a means of enhancing performance. It might be worth some experimentation.
John,
I used to. However since C3D doesn't allow a Partial Open I don't have that set any more. I've never studied if it makes a big difference when using Xrefs.

Thanks for responding guys. I appreciate all the input. I am going to experiment with this a bit. I will follow up with any inmportant findings.
Allen,
Why did you use the feature in the past and what is the relationship with the partial open command?
John Mayo
Back in 2009 and before the Layer and Spatial indexes were used to do a partial open based on layer or location. I haven't worked with it for a while because Civil 3D doesn't allow a partial open. With all the dependencies between objects you can see why. I read the 2014 help on partial open and it now seems they're useful but may not be necessary.
