AutoCAD LT :: Lags When Two Drawings Are Open?
Sep 3, 2013
about 3 days ago for some reason my cad is really slow when i have two drawings open at the same time. it lags when i am panning or zooming.
it just started randomly and the computer i am using is new and started using it about 6 months ago and it has been fine since i got it except for the past few days.
it doesn't matter what drawing file is open it lags. RAM is alot (8gigs) again this just started happening randomly. everything else is fine
i am working on AUTOCAD LT 2014

I tried the following method to save all drawing currently open. It always fire fill access arror, whereas AutoCAD can save the file wihthout any issue. Here I am checking for drawings that not even saved once and ask the user to take action for those files.
try
{
DocumentCollection docs = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager;
foreach (Document doc in docs)
{
string dname = doc.Name;
string s = doc.Name.Substring(doc.Name.LastIndexOf('\') + 1);
[code]....

I'm trying to add a block with an attribute to a drawing. The command works if there is only one drawing open, but when there are other open drawings then the block doesn't appear. Strangely if I select the block in the block editor and then close the block editor the block suddenly appears. Do you know what is causing the block to not appear when other drawings are open?
I included the code below. "s1" works but "s2" has the strange behavior of the block not being visible.
[CommandMethod("s1")]
public void AddBlockWithAttributeToDestination_WithNoOtherDrawingsOpen() {
var attributeValue = "1234";
var destination = Application.DocumentManager.MdiActiveDocument;
using (var transaction = destination.TransactionManager.StartTransaction()) {
addBlock(transaction, destination.Database, attributeValue);
transaction.Commit();
[code]....

I'm running 2013 C3D and have a quirk that my drawings zoom out when I first open the file. I'm not even sure what they are zooming out to as it is not 'Extents'.

For some reason, one of our PC's running MEP 2012 has suddenly started to only open drawings in read-only mode. The same drawings will open just fine on other PC's so they / their folders are not set to read-only in windows. The user also has the exact same access rights on the server as the others.
The strangest thing about this is the following warning box that appears on screen. see attached.
For some reason, the alert message which displays the full path of the dwg in question, has it's path modified with a date and time stamp prefixed with a '@' symbol. Needless to say the folder '@GMT-2012.07.17-11.00.04' does not exist. In 18 years of playing with AutoCAD I've never seen this one before.

I usually open several drawing and use"drag and drop".
But something has happened.
Now, I can only open one drawing at the time. When I try to open the second drawing, the program close down the first.
What have I done ? and what shell I do ?

But, I've lost the ability to open drawings with the traditional "tree" type search.... Something like Windows Explorer. Just before this happened, I had blown up a drawing by, apparently, importing one too many iges files. Got a message that Autocad had an error and was shutting down. Now, when I hit file/open, I get nothing but the command line asking me to enter the drawing path.

Currently when I open up multiple drawings (opening them up one at a time) they all appear in the same window (one instance) of AutoCAD.
I want each drawing to open in separate instances so I can view them on separate monitors (and close one without being asked to close them all).
I have tried changing the SDI system variable from 0 and 1 (and vise-versa)
I have tried changing the windows default program from AutoCAD Application to AutoCAD Launcher (and vise-versa)
I have set the TASKBAR system variable at both 0 and 1 (and vise-versa)

Every drawing I created using LT 2009 opens now with "Open Drawings - Errors Found" window telling me the drawing has xxx numbe of errors and asking me whether to continue or close and recover. Why is it doing this?

I was trying to retrieve a list of the currently open drawings before running a batch script in VB .Net 2008 so that the program can check the selected file listto update against whats open already to make sure that the file isnt read only.

It seems that once my newly purchased autocad lt. 13 opens up a drawing created by an other co-worker in autocad Lt. 11, it automaticly converts to 13 and now the person using 11 can no longer open the file. what I should do?

I cannot get this feature of 2013 to work for me. When I grab a selected item and drag it to the new drawing window, I get at round circle with a line through it or sometimes I get a command that says invalid.

AutoCAD LT 2014...Any way to turn off the bar near the top that shows what drawings I have open? I like to use a clean looking CAD screen and this is an entire line of stuff I don't need to see. Yes, I'm still using the AutoCAD LT classic workspace (modified of course).

I open a blank 2012 session with drawing1.dwg, then I open a new dwg "drawing2.dwg.So one session, two blank drawings.
I netload an assy into drawing2, and can run a lispfunction from it.
I netload the the assy into drawing 1, and cannot run the lispfunction.
it says "error: no function definition:..."How should the checking process normally be done, to see if a .net dll is loaded?I normally do this with lisp:
(if (not mylispfunctionname)
(progn
(COMMAND "NETLOAD" DLLNAME)
(vl-arx-import 'AcXt-GetColorNoBylayer) ;since I compile to separate namespace vlx's
)
)
The separate namespace thing is secondary, and I am just talking about loading dll's by hand, and running functions from them on command line. Once I get that ironed out, I can tackle how to detect from inside a vlx.I saw Kean's post on making a dll to detect what dll's are loaded, but its not even working for me once I have that info.

How can you limit the number of open drawings in a session of AutoCAD. Now I can open up 35 drawings in 1 session which will take up a huge amount of memory.
Is there a variable or something like this that I can limit this to 4 for example?

I'm trying to OPEN some legacy MicroStation drawings through AutoCAD. I have done this with nearly 400 files thus far but there are a dozen or so that are coming back with an error message reading 'YOU HAVE A SELECTED AN INVALID OR UNSUPPORTED DGN FILE'. I can look at these through Bentley Viewer, but do not have a full version of MicroStation to try and fix things.
How to fix things via AutoCAD?

Autocad 2012 was working fine until a week ago when it started taking a long time to open drawings--even search for drawings on our network. It also takes at least 30 seconds to save files, where it used to take 5 seconds at most.
I found the AutoCad 2012 and AutoCad LT 2012 SP1 Ribbon Hotfix, which sounded like my problem, but it is for Product Version F.107.0.0 and I have Product Version F.51.0.0.

A few of my design drawings are taking a long time to open from cold. They are not particularly complex drawings and all the files / assembly etc. that are referenced on them are correctly stored and are not corrupt or 'sick'. Why are these drawings taking so long to open? waiting for them is slowing me down considerably.

Since upgrading to AutoCAD LT 2011 I cannot use the Design Center for inheriting objects such as layers, blocks etc between drawings. I have a few different drawings open which are displayed in the tree view of the 'open drawings' tab in the Design Center. But the objects of the drawings are not displyed. No +-sign in front of the drawing name, no icons in the icon field, just a summary at thebottom saying '0-items'.
I have tried reinstalling AutoCAD.

why Autocad 2012 opens one window per drawing as opposed to Autocad 2007/2008 opening one window for as many drawings as you have open. (I also don't care to group/ungroup similar programs through Windows 7.) This must be an Autocad 2012 program default that I can't figure out to change.

Whenever I open a drawing in a certain project this error message always pops up.Some of the message details are:
-Parameter ERRCODE; Value 786433
-Error 786433 - Conflict between data tables in open drawings (57 consecutive occurrences)
-Parameter: APPLNAME Value: ad
-Parameter: CLASSNAME Value: airfield
this message box stops popping up when I open the drawings?

When I open a drawing, if I have other drawings open, the drawing I am opening does not come up maximized. I have to drag the edge up to fill the screen.
Is there a setting for having all drawings open up maximized? The first drawing I open always comes up maximized.

I finally gave in and applied the LT14 registry "fix" to correct the flashing icons, monster lags, etc...might of fixed those issues (not sure yet) but now when I tap the F8 key to toggle Ortho on/off it also toggles on the Grid (which I do not want). If I keep tapping the F8 key it cycles through turning Grid on/off and turning Ortho on/off.
F7 still works like it should, toggling the Grid on/off.

I don't remember ever using this checkbox on the Publish dialog box but today i want to and i can't figure out how to make it work. The help file ~seems~ to say that if i select this, the contents of all open documents (layouts and/or model space) are automatically loaded.... but they don't.
I know i can pick the Add Sheets button and manually select all the drawings i have open but doesn't that defeat the purpose of this checkbox?

Im using Inventor 2014 SP1 on a HP Z620 with 2 CPU - 16GB Ram.
Graphic card is a AMD Firepro W7000 4GB.
When i am rotating a big assembly 500+ it doesnt lag that much, but when i have a sketch turned on at the same time, the graphic lags extremely when rotating.
I have tried all the recommended drivers and the newest drivers and nothing changes.
I tried different hardware settings in inventor (Performance, Compability, Quality) and there is no difference.
I also tried to change the graphic Card with a Nvidia GTX 660.
It rotates much better (smooth) in big Assy than my firepro but it is having the same issue when having a sketch turned on.

Whenever I place a copy or paste from the clipboard AutoCAD freezes for about 5 -8 seconds and is very annoying. Time is money people. I know it's not a RAM issue. I don't have the problem with 2011 when I go back to it. What gives Autodesk? When is the next service pack due? This only happens with teh copy command

I have ACA 2013 (student version) running in the Windows 8 environment. I cannot open anything drawn in a previous release nor can I open a drawing created in ACA 2013 that was installed on the Windows 7 platform.
I have tried to drag in the drawings through design center. That worked for a while now when I try that it causes ACA to crash. Also I have tried multiple drawings that were created in several different versions of ACA. (2004, 2006 and 2009)
As a side note I was able to open those files in ACA 2013 running on the Windows 7 OS.
