CIVIL 3D - VERY SLOW

[Anonymous]

Hello to all someone can tell me why this civil 3D file is so slow, when I change the alignment, when I edit a section when I update the corridor and much more, Iwork with Civil 3D 2021.

My workstation is a Inte Core I7-4790 CPU 3.6 gHZ - ram 32 Gb

Thanks in advance

Hi @Anonymous ,

If it's happening with one drawing, try Audit and Purge. 

Try working on the local drive instead of Network. 

Make sure you have installed all the updates for Civil 3D and AutoCAD

Well, 5400 meters is a pretty good distance.  BTW, it took my computer 3 min 40 seconds to do a Audit.  There were 6 errors.  The computer I use on my email computer is I7-7700 4.2 Ghz.  Pretty similar.  Using 2021.

Thanks Bill,

a question, but does it seem slow to you too, when for example you move the grip of an alignment?

Yes it seems slow.  My longest corridor I am on right now is 3700 feet which is considerably shorter than your corridor.  It sails right through.  You just have a few regions, it would not take too long to change the frequencies to something considerably longer to do your design.  Then go back and change to the shorter frequencies.

BTW, you have no purgeable items.

Sorry Bill, my english is not great, what exactly do you mean with "Then go back and change to the shorter frequencies".

Thanks

[wfberry]

You set various frequencies for your regions under Corridor - Parameters - Regions.  For example, you have curves set at 2 meters, change them to 10 perhaps until you get finished.  Then go back for final work to your 2 meter spacing.

Perfect I understand.

Grazie tanto Bill.

Hello!

Very slow is very subjective 🙂

I've DL your file, opens up farely quick, looks simple enough. However, you ARE rebuilding feature lines, surfaces, slope patterns

I tried grabing a tangent grip (middle so it moves two curves), and it takes 18 seconds for the event viewer to pop-up. WHen i selected "automaticaly rebuild corridor" it took 25sec. When i edited the frequencies to all be the same (didn't check them individualy), and disabled OFFSET TARGET SAMPLING it dropped to ~20secs.

Any use of that info for comparison?

Cheers,

Iggy
