MicroSurvey CAD 2021 Known Issues
Posted by Jeran Hopfe on 12 May 2021 09:21 AM

The following is a list of critical bugs or important limitations that users should be aware of which affect MicroSurvey CAD 2021. It is not intended as an exhaustive list of all issues.

Important Note: If you ever experience a crash when using MicroSurvey CAD, when you are asked if you would like to send an error report, please always select Yes to send the report. MicroSurvey and IntelliCAD programmers can use these error reports to help investigate and fix crashing problems that occur within the program, even if it is a problem that is not easily reproducible. Please note the crash reports are not actively monitored for technical support purposes.

Please contact technical support if you experience any problems.

Problem: When exporting from an imperial (International Feet or US Survey Feet) project to shapefile, the projection file is written as metric.  This units mismatch is not accepted by some GIS programs, such as Google Earth or QGIS, wherein the projection file units are used to assume the units for the entire shapefile, making the shapefile appear to have incorrect units.

Workaround: The .prj (projection) file is an optional file in the shapefile.  In imperial projects, uncheck the checkbox to write projection data and import the shapefile into a GIS project that has had the coordinate system manually set.  The remainder of the shapefile data is correctly written in the appropriate imperial units.

If you must have a .prj file as part of the shapefile, you can modify the exported shapefile in a text editor manually, converting the projection units and noting the units and conversion factor in the file, as described in the following online article from ESRI:  Most projection details are available online at or, so you may be able to simply input the projection details as written there, ensuring units and conversion factor to metric are noted as described in the ESRI article.

Status: Partially fixed in MicroSurvey CAD 2021 Hotfix.  Coordinate systems with units matching project units will now be exported as expected.  Will fully fix in a future update.

Reported: October 27, 2020

Problem: Selecting closed, splined polylines for shapefile export will cause the program to crash.

Workaround: Change the "Closed" property of splined polylines to "No" prior to exporting.

Status: Will be fixed in a future update.

Reported: September 16, 2020

Problem: Smooth Contour causes an extra segment to be drawn from 0,0 to the first vertex of all smoothed contour polylines.

Workaround: The easiest method is to use MicroSurvey CAD 2020 SP2 or earlier to smooth any contours.  You may instead explode contours, delete erroneous segments, and join them en masse, but this is potentially a very long operation as the contours have been smoothed and contain many segments.

Here is a video going over the workaround.

Status: This is a known issue to IntelliCAD and it will be fixed in a future update.

Reported: November 6, 2020

Problem: BIM Undlerlay import does not work, and crashes the program during the import process.

Workaround: The current workaround is to use MicroSurvey CAD 2020 SP2 to import any necessary BIM files.

Status: Will be fixed in a future update.

Reported: November 10, 2020

Problem: Some computers will always have a message when trying to install saying that it requires admin rights to install. We've found that this is caused by an issue with the installer of the program.

Workaround: Some computers are able to solve this issue by turning of your Antivirus and/or Windows Real Time Protection. We recommend disconnecting from the internet before trying this.

Status: Fixed in MicroSurvey CAD 2021 Hotfix, released December 22, 2020.
