DWG file lagging too much

[ArthurADas]

Hi

A few days ago i was working with a file and everything was working perfectly, not a single problem related to lag.

Suddenly, when i opened my file yesterday, it became really weird, the annotations are pixeld, when i pan civil 3d lags, when i PAN using the scroll button sometimes the COMMAND stands working even when i release the scroll button, and the use of memory coming from this file is almost 12x higher than a similar file. 

I dont know what happened, or if i did something different that made this file to look weird, but there is something wrong with it. THIS IS HAPPENING ONLY IN THIS FILE SPECIFICALLY

Solutions that i tried: AUDIT (No errors found), RECOVER (Nothing changes), PURGE (Nothing changes), SELECTIONPREVIEW= 0, COMMANDPREVIEW = 0, REGEN COMMAND doesnt not work, REGENALL idem, and the COMMAND REGENAUTO is set to ON, DISABLING GRAPHIC PERFOMANCE (Nothing changes)

I cant attach the DWG here, but i can send it on a personal/private email if someone wants to help me out.

Appreciate any help

Obs: I attached three prints here, one from the annotation, the second one is when i PAN around the file, and the third is the use of memory from a similar file. The weird part about the second image is the behavior from the tiff images, before i could see them normally when i used the commando PAN, but now a few of them vanish,

Try Wblocking out the entire file. Select the drawing entities by Window. Not by using All. See if you have the trouble in the newly created drawing.

Looks to me from your image I2 that you have a point cloud in the drawing. If this is the case your going to have that until you reduce amount of data your using.

Ok

I'm trying your suggestion right now, as soon as my DWG opens again i return with an update

Thanks

I see your visual style is set to 3DWireframe.  That could be causing some of the issues. Is that what you normally use? If not try changing to 2DWireframe.

@rl_jackson 

I thought as well, but i did  a clean up, deteled every single thing in this drawing searching for a point cloud and i couldnt find it

[ArthurADas]

I CANT BELIEVE IT

THE **** SOLUTION WAS RIGHT UNDER MY NOSE

i just changed to 2DWireframe and all worked all perfectly

its so beatiful seeing everything normal again 😊

Thank you guys so much for all your suggestions

If you have a Point Cloud. You usually can't see it in 2D wireframe. 

Point clouds are not displayed in 2D visual style" in AutoCAD
