does this seem to be drawing specific? I've work on some jobs where this was a constant problem, but as I recall, it was limited to only some jobs/drawings/attached xrefs or drefs
Admittedly, this is only happening in a drawing that contains only the needed data to create a moderately complex, proposed roadway corridor.
That said, this model does contain more than others that I've done, as this was a vanilla AutoCAD drawing, drawn using Land Desktop 2005, and has no LDT database to import... Instead I've had to manually recreate each-and-every-single Alignment, Profile, Profile View, Assembly, etc. so that I can model the multiple roundabouts, and handful of intersections, before I even get to the grading of ponds, etc. for this adjoining proposed subdivision.
I've only been here a little more than 60 days, but so far most of my work in similar... It's one of the reasons the owners hired me, as their existing staff have IDS 2014 installed, and have been sent out for 3 days training, but don't use it (
still using LDT 2005)... Hand drawing vertical profiles, scaling title blocks in paper space so that the viewport scale is 1:1, all sorts of nonsense.
The new server I'm ordering today, will present the opportunity for me to take LDT offline in short order, as I shall not be migrating the license(s) on the server, and all of our IDS 2014 installations are on each user's computer... All IDS 2014 licenses were installed prior to my being hired on, with exception of two, so I'm not really sure if I can/should change that then as well?
