It is not uncommon to see this problem around the AutoCAD world. You press Ctrl+S or click the save icon and you get a message that says something like this:

"Unable to save to drawing K:\mypath\mydrawing.dwg
Drawing saved to SAV98C2.tmp"

In order to understand why this error happens, you need to understand how AutoCAD saves a drawing.

When you save a named drawing in AutoCAD, it actually does this (*steps 2 and 3 only occur if you have .BAK file creation enabled) Read more about Unable to save to drawing....

When making entity selections in AutoCAD, sometimes the results can be unexpected. You may select a hatch object and move it its associative boundary stays put, or you may erase a line and other geometry disappears with it. Situations like this can be controlled by a system varible named PICKSTYLE.

PICKSTYLE controls two things, how associative hatches and their boundaries behave and how grouped objects behave. Let's take a look. Read more about Controlling AutoCAD selections with PICKSTYLE

I have been recently running across AutoCAD DWG files that contain hundreds of non-purgable linetypes, some with strange names, some that appear to be nested in mysterious blocks, etc. With help from the Autodesk Forums and some independent research, I became pretty sure these were created by importing Microstation DGN files.

Does your AutoCAD recent file list work for you, or does it fill up with seemingly random .DST (sheet set) files instead of the last .DWG files that you worked on? The latter is documented all over the Autodesk forums, here is one such thread, dated back to 2008 (yes, it has been an issue for that long). In another thread, Jeff Mishler from Quux Software has provided a standalone application (at no cost) to help you manage your recent documents list.

The AutoCAD Recent Documents List Manager allows you to select and remove items from this list easily. Below is a screen shot of this app. Read more about Managing the AutoCAD Recent Documents List

AutoCAD WS is now AutoCAD 360. The online/cloud version of AutoCAD has seen over 12 million downloads and 11+ million registered users since it was introduced.

Below is a list of known issues in Civil 3D. Some of these may be inherited from AutoCAD. Always confirm issues for yourself since there are many variables at play. PLEASE report any additions or corrections needed by leaving a comment with as much detail as possible.


Product Version Description Addressed?
Civil 3D 2013 When LAYERDLGMODE = 1, if you do not have the option "Apply layer filter to layer toolbar" checked on, then layer filters do not work in the layer manager. Broken in 2013 and 2014. Fixed in 2015
Civil 3D 2013 When you insert a point from the Survey database, it automatically zooms you to that point. But the zoom level is way too small (viewsize = 0.0002). There is no way to control this. Broken in 2013. Seems to be fixed in 2015, more testing needed to confirm.
Civil 3D 2013-2015 With the system variable "Startup" set to 1, when you start Civil 3D and select a sheet set from the list of recent files, Civil 3D will continue to open, but the sheet set is not loaded in the SSM palette. No
Civil 3D 2013 With the system variable "Startup" set to 2, start Civil 3D and open a sheet set from the recent files on the application menu. Try to open a drawing from the SSM (Civil 3D is still in a zero-document state at this point). Multiple fatal errors ensue. Fixed in 2014
Civil 3D 2013-2015 With the following system varibles set like this [Startup = 1, SSMAUTOOPEN = 1, SSLOCATE = 1], if you select a .dwg file to open from the startup dialog, the .dwg file opens fine, but the related sheet set (if any) does not load in the SSM palette. No
Civil 3D 2013 The recent files list in the application menu, and in the Startup dialog box (if enabled) always floats sheet set files (.dst) to the top (even old ones), forcing recent .dwg files off the list. No
Civil 3D 2013 Under certain conditions, when switching from a layout to model space, the ucs in MS changes by itself. Fixed in 2013 SP1
Civil 3D 2013 If you click a column header to sort the parcel listing in the prospector, the list disappears. More info and a workaround here. Fixed in 2013 SP2
Civil 3D 2013 When plotting from model space, and using the window selection method, if you zoom with the scroll wheel while picking your window in the graphics window, you get an error and have to press ESC several times to get out of a loop. Some people report that the loop is impossible to get out without killing AutoCAD. Fixed in 2013 SP2
Civil 3D 2013 Under certain conditions, layer names in the layer properties manager palette (LayerDlgMode = 1) will be seemingly 'double-spaced'. Closing and opening the layer properties manager palette will generally restore the smaller spacing between layer names. Forum post with screenshots. No
Civil 3D Unknown-2015 If you open a drawing that contains only a dynamic block, you are prompted to go directly into the block editor. While in the block editor, if you make changes to the block definition and click "Save Block", then "Close Block Editor", the block editor AND the drawing closes, without saving your changes to the DWG file. No
Civil 3D 2011-2013 When labeling contours using the ._AeccAddContourLabeling command while the CURRENT layer is locked, you can only draw the first tangent segment worth of labels and subsequent segments are ignored. Workaround is to make sure the current layer is not locked. No
Civil 3D 2007-2013 At certain times, the Profile and/or Alignment Layout Tool (sort of like a toolbar) will appear but all the tools will be grayed out. The current 6 year+ workaround is to shut down Civil 3D and restart it. No
Civil 3D 2013 When exporting to DXF format, you must remove the geographic location assigned to the drawing before you create the DXF file. Otherwise the DXF file will not open, even with Autodesk products Seems to work OK in 2014 and later
Civil 3D ????-2014 Within a surface style, if the point color is set to something specific then any other component set to BYBLOCK will also change to match the point color. No
Civil 3D 2014 Surface analysis results are lost during a rebuilt or synchronization. Autodesk says this change from earlier versions is "as designed". More info here. 2014 SP1 Readme says YES. Not tested by us.
Civil 3D & Map 3D 2014 MAPIMPORT or MAPEXPORT does not work. Autodesk has provided a manually applied workaround, available here. Yes and No
Civil 3D All? Toolbox->Station Offset to Points report. There is no way to sort the report on any column. Might be considered a missing feature, but the grid control in the dialog contains standard click-able headers that in any other dialog, DO perform a sort. No
Civil 3D 2014 When you synchronize a pipe network reference, pipe styles will reset to the "Default" pipe style. More info here, including a workaround. No
Civil 3D 2014 The medians crossing centerline use to work, now it doesn't. Autodesk Support has been confirmed as defective. (Details here). No
Civil 3D 2007-2014? OverlayMillAndLevel2 Subassembly issues (Details here). No
Civil 3D 2014 Structural Material Volume Shapes issues (Details here) No
Civil 3D 2014 When using Profiles from Corridor Feature Lines the Intersection Wizard produces the following message at the end of the process, and cannot lock the Secondary Profile to match the Primary Road Profile. (Details here) No
Civil 3D 2014 Formula colums for simply computing ItemQTY*Item Cost in a Data Extraction table for a current project do not work. (Details here) No
Civil 3D 2014 Intersection widening profile blows up upon horizontal editing. (Details here) No
Civil 3D 2014 The Override Maximum Slope option is not working. It is not pinning the daylight slope to the Target surface at the ROW. (Details here) No
Civil 3D 2014 The Section Editor is not turning off layers in Section View. It is showing all sorts of skewed entities. (Details here) No
Civil 3D 2014 Daylight Standard is not creating a ditch when the Cut Test point is calculated to be below the target surface. (Details here) No
Civil 3D 2009-2014 Various QTO issues (Details here) No
Civil 3D 2013-2014 Adding a subassembly to a LinktoMarkPoint subassembly that is located on an Offset Assembly causes a fulll software crash in Civil 3D. (Details here) No
Civil 3D 2013-2014 Civil 3D will reproject images inserted using MAPIINSERT on the fly, ignoring the UNITS field in a GeoTIFF header. (See comments for more details) No
Civil 3D 2014 If C3D 2014 is installed from the IDSP suite, as soon as you copy or create a new workspace it's corrupted. This corruption causes profile views to no longer show line weights correctly and sometimes the right click menus to default back to base ACAD. No
Civil 3D 2014 If you add superelevation to an alignment that is a baseline for a corridor, the Alignment from Corridor no longer works correctly during the curve. Only a straight segment is created from the corridor feature line. No
Civil 3D 2015 By default, the path "C:\program files\autodesk\autocad 2015\map\support\en-us" is omitted from the support file search path during installation, which causes the MAPOPTIONS command to display only at the command line instead of using a dialog box. More info here and here No.
Civil 3D 2015 Survey Database edited and/or created with 2015 cannot be opened by a previous version of C3D. [Ref] No.
Civil 3D 2015 Delete a survey figure from the panorama results in a crash and the figure(s) not deleted. [Ref] No.
Civil 3D 2015 Map support path not created on install, resulting in Map commands not working. [Ref] No.
Civil 3D 2015 MAPIINSERT still not reading the GeoTIFF header UNITS at all, resulting in some images in US survey feet being brought in as meters. [Ref] No.
Civil 3D 2015 Material Take Off computes the half areas of the materials, when you have more than one baselines. [Ref] No.
AutoCAD 2015 Cannot copy a layout by selecting a layout tab, hold CTRL and drag left or right. [Ref] No.
Civil 3D 2013?-2015 Manage > Import Styles command does not work correctly. Some styles are not imported. Some settings are not imported. Object Layers are ignored. Certain text style settings are ignored. No.
AutoCAD 2015 Hatch objects do not honor the XDWGDFADECTL system varible, so they do not fade in xrefs. Fixed in AutoCAD 2015 SP1, which also fixes Suites that include AutoCAD.
Civil 3D 2006-2015 If you use the built-in command LAYMRG to merge layers that are used in Civil 3D styles, the styles become corrupt. What actually happens is the layer entry in style becomes blank. Running AUDIT will set this empty layer to layer "0" for some but not necessarily all of the corrupt styles. See this for more detail. No.

Notice that the panel is light gray and the icon text is white, which makes the text difficult to read. Here is how to fix it..... Read more about AutoCAD Places List hard to read?


Today, March 29, is the 8th birthday of CAD Panacea. Inspired by Shaan Hurley, our first post was a simple tech tip back on March 29, 2005 on the old free Google blogspot system. Over the years we moved to our own domain, been through a few makeovers, and watched many other CAD blogs being born. Hopefully CAD Panacea has helped, informed, and provoked thought in many of you. Thanks to all of our readers over the years, especially those who leave feedback. Read more about CAD Panacea 8th Birthday
