Erase All takes forever

[cjneper]

We have one 64 bit Windows 7 PC, and that is the one that is having this problem:   When I do "erase" "all" to erase everything in the drawing, Autocad Map takes about 10-15 minutes to do this.  On our 32 bit PC's this takes just seconds on the same drawing.  The drawing I am testing on has 140,000 entities.  Is there a setting or variable for number of entities somewhere??.... I am at a loss as to why the newer faster PC with more memory is choking on this.

Thank you for posting to the Autodesk Discussion Groups.

This unfortunately is a known issue that only affects the 64-bit releases of AutoCAD Map 3D 2013, 2012, and 2011. A fix is still being investigated by the Map 3D developers.

A workaround for this is to launch AutoCAD Map 3D as AutoCAD. Here steps for doing so, and the results of a recent test:
1. Copy your existing AutoCAD Map 3D Desktop Shortcut.
2. Edit the Shortcut, adding a profile switch to the end
e.g.: "C:\xxx\AutoCAD Map 3D 2012\acad.exe" /P "AutoCAD"
This creates a new Profile, which is pure AutoCAD.
4. Try erasing objects again.

No Map ARX Routines are loaded, so you can delete e.g. 300000 Object in less than 3 Seconds.

I hope this works for you until a more permanent fix is released. I'm sorry, but I do not have information regarding if/when a fix might be released.

Any codefixes will be announced to the public via readme on our website.

I have linked your case to the change requests for this issue, which will draw further attention to it.

Thank you for reporting it again to us.

I will try the workaround that you suggest, but I assume then that using a Plain AutoCad profile will mean that I no longer have access to Map commands?

How does an issue like this make it through 3 releases of Map without a solution?  When I was having issues with 32 bit systems being unable to handle large datasets, I was told that Autodesk now recommends a 64 bit system, which does handle large datasets better, but nobody said "Oh by the way, you won't be able to erase those large datasets".... ???  Truly baffling.

[cjneper]

Is it a possible workaround to install the 32 bit version of Map on the 64 bit PC?  Will that work?

[phil_borycens]

The installation of 32-bit on 64-bit will detect your system bitness and stop you early in the process. You might be able to hack it, but then it would be an unsupported configuration.

[cjneper]

Creating an "Autocad Only" profile as directed caused me to lose all Map and Raster Design functionality in my original Desktop Shortcut.  Now how do I get them back?  It keeps telling me it can't find certain application or DLL files, and that I have to reinstall the program!  All I did was a profile switch.  There has to be a simpler way to get those back.  They are gone completely out of the CUI.

[phil_borycens]

I'm sorry. That is very strange. How about running the MENU command and choosing Map.CUIX? Does that fix it?

[cjneper]

No luck.  The menus are back looking normal, but only some of the map commands work.  The Map Import and Workflow Designer commands give error messages, that they cannont fnd a needed dll file, but do not specify what file they need.  It appears a search folder was lost, but they all seem to be there...

[phil_borycens]

You can either run the Reset Settings to Default utility that comes with AutoCAD Map 3D, or check your paths against mine:

[cjneper]

That did it.  The Bin/Fdo  folder was missing.

THanks

Yes having same problem.... massively painful. Tried deleting 1,000,000 or so spot heights, left running overnight, couldn't do it. WT? So tried it in microstation - took less than 1 second - almost instantenous. Even deleting 100,000 objects seems to take 5 minutes in 2012. Same deteting done in old 2000 version I still have running - also almost instantaneous. What a pain.
