Specific issue and things to look for when altering Survey databases and get the fatal error code Opening a Survey database for Edit, or creating a new one causes Civil 3D to hang and fatal error with

Plotting to PDF with PDF underlays that plot as raster images and how to fix that

You have your Pressure Network Catalog Path set to a custom location in your profile and after opening a different drawing it resets to a different location or to the default location.

You have a surface that has Elevation analysis done and you have set the layer of the elevation banding to have a transparency value (to see the underlying geometry), and the TIN Lines show up in plot

Issue: You are plotting drawings that have OLE objects, and the plots with the OLE objects are either missing or poorly represented

Issue: When importing XML files, they do not come in properly Causes: This problem is triggered by the units of the exported XML and the units set in the DWG file you are importing into

Issue: Running Recover on a drawing shows an AcDbSpatialIndex error was present and repaired:

You are using AutoCAD Architecture or AutoCAD MEP 2024 or older in an environment that uses Vault and cannot enable Sheet Set features when using Sheet sets.

When bringing in a custom dynamic block with Attributes, and that dynamic block is Annotative, via the tool palette, when changing the Annotation scale, the Attribute text reverts to original size

When plotting a PDF from Civil 3D, where text is below a certain text height (as displayed) and depends on drawing viewport scale, the text will no longer print correctly

There is a specific plotting behavior with the AutoCAD-based 2026 software when using anything but the standard rectangular viewport in a layout tab.

When you open a drawing or attach a reference template while active in a locked or unlocked viewport, the viewport zooms out.

You are trying to use the CHSPACE command (Change Space) to have objects move from paper space to model space or vice versa and they are not changing to the selected space.

Profile Labels Shifting with Plotting Buffer when an Axis offest is applied

You either attempt to create a Survey Database in a folder or attempt to open one and get an error message

You see multiple plot.log files in many places across network folders and on your own local machine

This problem can be due to a number of possible reasons. Here's what you need to consider and changes you can make.

When deleting layers in Civil 3D, using the LAYDEL command, unexpected behaviors occur.
