Problem Description

A bug has been found in Descartes SELECTSeries 4 and SELECTSeries 5 that can affect the speed of the display. This occurs when users use Model By Section, Templates as well as Sections following path.


We are creating a large quantity of temporary files that are never deleted. These files are created in your windows temp folder.


Depending on the machine, this can fill your hard disk drive space and lead to numerous files that can slow down the OS when it tries to scan the folder.

Steps to Resolve

We have filed Defect 71592 for this bug. We are working on a maintenance release that is scheduled to be released in March 2014. A simple way to reduce the annoyance is to delete the *.TMP files in the concerned folder. In order to make it simple, a batch file can be created that does it and starts Descartes. Using a shortcut to this batch file will start Descartes and clean up the temp folder each time you launch the product. The following is an example of the Batch File. You will need to adjust the paths in the .BAT file.

set folder="C:\Users\User.Name\AppData\Local\Temp"

cd /d %folder%

del *.tmp

del *.TMP

Start "" "C:\Program Files (x86)\Bentley\DescartesStandAlone V8i (SELECTseries 5)\DescartesStandAlone\DescartesStandAlone.exe"



To determine how Descartes is being started you can right click on your Descartes Icon on your Desktop and select Properties and look at the Target path.

Bentley Descartes for MicroStation:


"C:\Program Files (x86)\Bentley\MicroStation V8i (SELECTseries)\MicroStation\ustation.exe" –wudescartes


Bentley Descartes Standalone:


"C:\Program Files (x86)\Bentley\DescartesStandAlone V8i (SELECTseries 5)\DescartesStandAlone\DescartesStandAlone.exe"


You can edit your Descartes Icon on your Desktop shortcut to point to the Batch file and use the existing Icon or you can make a copy of the Descartes Icon and edit the Icon copy and point to your batch file.
