Huge gaps in Windows Add/Remove programs list
Over the years, numerous Autodesk products have caused huge gaps to appear in the Windows Add/Remove Programs list. This is caused by an incorrect registry entry.
Workarounds: If you’re very comfortable with editing your systems registry, look for all Autodesk programs under HKLM\Software\Microsoft\Windows\Currentversion\Uninstall until you see one that has a “,-1″ following the path shown in [...]
Can’t change leader arrowhead back to “closed filled”
AutoCADs quickleader settings allow you to specify how you want the arrowhead to appear. In most cases, “closed filled,” is the default arrowhead block. If you happen to change the block to something other than “closed filled”, (for example, “dot”), and then draw leaders using the new style, then it becomes impossible to set it [...]
VBA can’t explode non-uniformly scaled blocks
As of AutoCAD 2004, VBA can no longer be used to explode non-uniformly scaled blocks although this could easily be done with earlier releases.
Test with the following snippet:
Sub ExplodeNonUniform()
Dim oLine As AcadLine
Dim oBlock As AcadBlock
Dim oBlockRef As AcadBlockReference
Dim StartPoint(2) As Double, EndPoint(2) As Double
StartPoint(0) = 0#: StartPoint(1) = 0#: StartPoint(2) = 0#
EndPoint(0) = 1#: EndPoint(1) [...]
Dynamic Blocks don’t work
In AutoCAD 2006, left clicking on a dynamic blocks “grip” does not work when a station is configured not to use any right click shortcut menus.
Since there are still a many users out there who prefer right click to always be enter and only enter, this is probably a design flaw. The fact that 2007 [...]
Short MTEXT entities cause sluggish performance with “thicken” selection preview
It appears that when PREVIEWEFFECT is set to a value which allows thickening (1 or 2) then short MTEXT entities observe this setting while larger MTEXT entities do not. Unfortunately, when moving the cursor over the entities that do observe the “Thicken” setting, performance noticeably hesitates.
Workarounds: Change PREVIEWEFFECT to 0
First Appeared: Land Desktop 2006
Status as [...]
Symbols insert at 1/12 of intended scale
Some (but not all) of the blocks that shipped with Land Desktop 2006 have some associated lisp code that runs when they are inserted. It appears that much of this code predated the new interpretation of INSUNITS, and wasn’t updated to account for it. When using Autodesk’s own functions to insert any of these blocks, [...]
“Partial Preview” displays incorrect information when plotting named model space views
The new “partial preview” like icon seems to indicate incorrect image positioning when plotting named model space views.
For an example, enter (or script) these commands:
_vscurrent
2
plan
w
ucs
w
setvar
osnapcoord
1
._rectangle
1380000,445000
1380010,445007.50
._-VIEW
w
MYVIEW
1380000,445000
1380010,445007.50
._zoom
e
Then, in the plot dialog box notice how the “partial preview” shifts when switching between plotting extents and plotting MYVIEW.
Workaround: Use “full” preview when plotting named views
First Appeared: AutoCAD 2006
Status as [...]
Missing commands
Commands such as BHATCH and XREF fail to work after running multiple plots when “plotting to file.” This is not related to the CMDDIA variable.
Workarounds: Shutdown and restart
First Appeared: AutoCAD 2006
Status as of 2007: Cursory testing unable to reproduce error. Touch luck 2006 customers.
LWDISPLAY automatically turns on when file is opened
On some systems, LWDISPLAY, which is typically a DWG-stored variable, automatically gets set to 1 in every file that is opened. Like other CAD Managers, I’ve seen this on only a handful of systems, but on those affected systems it is consistent. It’s not a bug in the profile, nor is it introduced anywhere in [...]
RTEXT confuses VBA
When using VBA to iterate through entities within any block (including modelspace and paperspace), the first time an RTEXT entity is encountered, an error is produced. Whats worse is that this error cant be trapped with “on error resume next.”
For example:
Sub RtextError()
Dim oEnt As AcadEntity
Dim oBlock As AcadBlock
For Each oBlock In ThisDrawing.Blocks
If Not oBlock.IsXRef Then
For [...]
LAYERP confuses associative hatches
After using BHATCH to create hatches against XREFfed entities, LAYERP may distort the hatch boundary.
Exhibit A – Xref or block has been inserted
Exhibit B – One of the referenced layers is frozen
Exhibit C – Associative bhatch
Exhibit D – LAYERP has been run
Workarounds: Use non-associative hatches under these conditions or thaw your layers using LAYTHW, -LAYER [...]
Scattered Toolbars
In AutoCAD 2006, if you use a main CUI with one or more partials, as well as an enterprise CUI with one or more partials, then your toolbars may not stay in place when you start AutoCAD, even when youve saved then in a workspace. It appears that, at startup, the toolbars are placed according [...]
