"...Guys,

I have a 2 month old machine –dell 3620 i7 7770k windows 10 civil3d 2018 running your .52 service pack 16gb memory gtx1060.

No matter what the user does he can’t get it to generate a "sheet view" [ed] without going into a massive memory leak (quickly grows from 1 gig used to 4 within about 2 minutes and continues climbing)

Picture attached:

...once title block goes away nothing else happens even leaving it over night – this is ONLY when there are a lot of xrefs – HOWEVER the profile works fine with no xrefs in a new drawing.

Thing’s we’ve tried:

• Almost identical computer with a 7700 instead of K series – 1060 gtx , same driver version on video card, etc.

• Reinstalling civil3d, deleting ASEcivil17 folder and re-extracting from zips

• Installing older video drivers cleanly, and matching video driver versions of working machines.

• Deleting temp files from c:\windows\temp and c:\users\(theuser)\appdata\local\temp

• Updating bios firmware version to current for dell 3620

Any ideas on how to fix this?..."

ASE:

Based on the indications you've given me, here are a few recommendations that "may" speed things up.

Purge unused objects in Xrefs

Many times I've seen templates used for each and every drawing. Hundreds or even thousands of layers are present in EACH drawing that may actually use a handful of those layers. Many of them are present just to support built-in styles that are never used. Check that you're NOT doing this. That route of workflow is not the most prudent. If you don't purge all those unused objects, by the time you xref all those drawings into your improvement sheet, you've amassed a GINORMOUS number of layers! Even though they contain no objects actually in practical use, they occupy memory...

Disable Layer Filters

Before creating the Sheet View with ASE, turn off all layer filters. This crash create a processing bottleneck when ASE attempts to manage the layers.

I'll continue to research more potential solutions & post them here.

Please let one of us know if you have any success (or not) with my recommendations.

I’ve disabled antivirus and tried.
