Migrating Workspaces 

By David Gerber - Support - A2K Technologies

There are 3 common reasons people have the need to migrate workspaces within CAD. 

  1. New Computer. 
    1. You would like to transfer your workspaces from your old computer to the new one. 
  2. Office Standards. 
    1. An office-wide standard has been implemented. 
  3. Upgrading to a Newer Version. 
    1. You have recently downloaded a newer version of CAD and it’s set to defaults. 


For a new computer or office standards, the workflow would be as follows: 

  1. Export Settings from AutoCAD – Windows Start – AutoCAD 20xx – “Export AutoCAD 20xx Settings 
  2. Import Settings – same area, except “Import AutoCAD 20xx Settings” 



When upgrading CAD versions on the same computer (provided you haven’t uninstalled the previous version), you will be asked if you would like to migrate settings. If that message didn’t come up (happens sometimes) you can go to the same area as the “Export Settings” but this time click on “Migrate From A Previous Release” and it’ll bring up a dialog box and ask to accept the migration from a previous version.  

If you have already uninstalled the previous versions before this step, you can import using the same steps as above, however, had you not exported the settings or have an office-standard workspace you can import, those settings would be lost once you uninstalled. It is highly recommended that you export those settings for safe-keeping before uninstalling your CAD versions. 

Resetting CAD to Default

This can also be a handy workflow for resetting CAD to default. If you notice your CAD starting to act up after importing a workspace, or perhaps working one day but not the next, it may be worth cross-checking: 

  1. CAD Updates.  
    1. Is your CAD updated to the latest version? 
    2. You can download the latest version from either the Autodesk Desktop App or through the Management Portal – 
  2. Windows Updates. 
    1. Type “Windows Updates” in the Windows Search Bar 
  3. Graphics Card Updates. 
    1. Test by turning off Hardware Acceleration by typing in – “GRAPHICSCONFIG" - in the command line and retesting. If it starts to act appropriately, check to see if your graphics card needs an update. 

If you notice performance issues on every file and it’s not isolated to just one file, export your settings and then reset CAD to defaults. Test those same files again and compare. It may be something within that workspace. Send it to us and we can try to isolate the reasoning behind it or escalate further to Autodesk. 



Sometimes the “Reset Settings to Default” or “Migrate From a Previous Release” is missing on some installs, if that’s the case for you follow the following Autodesk Article to fix this bug:  

Internal Origin Point 

By David Gerber - Support - A2K Technologies

The Revit 2020.2 update by Autodesk brought about a new feature in the “Site” category called the “Internal Origin Point”. Many people have noticed a 3D gimbal appear in their projects that wasn’t there before. New projects made after the 2020.2 update will have this turned off by default, however, older projects will now have this turned on in every view.  

Ideally, you would have it turned off in your office View Templates. This would turn it off in all of your views. 

If you do not have View Templates set up, you would need to do this in each and every view, as well as new views that are created within that project. You can also use Dynamo to quickly turn off the Site Origin Point in every view without having to open each one up. 

You will need to download the “” package in order to run the script. 

Once downloaded, open your chosen project/s and click “Run” at the bottom left corner. Dynamo will find every view in the file and turn off the Internal Origin Point, Project Base Point and Survey Point. If you’d like to turn them back on, either go into the individual pages’ VG settings, or change the script to say “false” instead of “true”, run the script, and all 3 will be turned on in every view. 

Revit Crashes 

By David Gerber - Support - A2K Technologies


Trend Antivirus 

Trend Antivirus has been known to cause crashes within Revit, usually with a saving error that says "Encountered a sharing violation while accessing...". We have also seen instances of Trend blocking Revit from launching.  
When looking at where that file path is going, it’s been linked to Trend blocking the Temporary Folder, which Revit heavily relies on when launching, saving, syncing, etc. 
In most recent cases, clients who were experiencing issues with Revit (who were also using Trend), all issues were resolved by disabling Trend. Most people have moved off of Trend early 2018 as it caused Revit to act up. 

  • The link has a supplementary link for other configurations for Trend that perhaps your IT can help you do. 

You can also try these whitelist options so that Trend causes less issues for you:  

Trend is a bit of a tricky one as they don't list too much on their website for fixes, I believe that's why most people switched to other antivirus software (at least in the AEC bubble). 
Trend had the following listed on their website when you search for "Revit". Instructions include excluding Trend from scanning the Temp folder.  

If switching antivirus' isn't an option, then hopefully the exclusions should help alleviate the problems you are facing. 


Site Designer / Precast 

Autodesk has plug-ins called “Site Designer” and “Precast”, both of which have been known to cause crashing within Revit. Site Designer is definitely the bigger culprit of the two, however, if you don’t need these plug-ins, we highly recommend uninstalling them.  
Many people install it due to it being available as a part of the “updates”, so people think it’s necessary.  
If you’ve noticed your Revit crashing after closing the last tab of a project or after closing a family after editing, this is often the case of Site Designer and a bug within it that’s causing this issue for you. 
We have spoken to the Autodesk Development Team and there has not been a fix for that crashing, unfortunately, other than to completely uninstall the plug-ins through the Control Panel. 
You can also quickly test this without uninstalling (perhaps if you need those two plug-ins at times) by going into the Plug-In folder and moving them out of that folder temporarily. When you relaunch Revit the next time, they will be unloaded and won’t affect Revit. Once you need to use them for your project, you can put them back in and use them. 

  • Revit plug-ins are found here: C:\ProgramData\Autodesk\Revit\Addins\ 
  • You will then see all years of Revit’s that you have. Open that year of Revit and move the Site Designer file. 
  • Tip: Copy/paste that UNC path to get there faster as Program Data is a hidden Windows folder. 

Working with CAD in Revit 

By David Gerber - Support - A2K Technologies

Many corruptions within Revit projects can be avoided by proper workflow. Importing CAD files is something we are all used to and has become a force of habit. Revit, however, does not function properly when CAD files are inserted. Ideally, you wouldn’t have any CAD files within the main Revit project, however, it’s understandable that this isn’t always avoidable. 


Before using CAD files within your Revit project, use this 3-step tip to clean them up as best as possible:  


Some workarounds to improve performance if you need to have use CAD files are: 

  1. LINK files into the project. 
    1. If they are temporarily used, it’s easier to see where they are located and easy to unload them to remove them from your project. Imported CAD files are much harder to find and more often than not, they require scripting to remove. 
    2. Unload/remove unneeded CAD files. CAD files add a considerable bloat to Revit. IF CAD files are visible in the view, the view navigation performance is affected. 
    3. It is advisable that CAD file should be cleaned up (especially civil files), purged, audited, PROXYGRAPHICS set to 1. 
  2. Create a CONTAINER file. 
    1. When collaborating, link your CAD files into their own Revit file, and position them accordingly and in appropriate coordinates. You can now link that Revit file into your project. This means you have control over where it’s linked into, filter it, unload/reload it, etc. 
  3. When needing them as a REFERENCE
    1. Avoid importing CAD and Explode CAD in project or families. Always use an interim file to convert CAD linework into Revit lines. In a new project or family Import the CAD, Explode and then remap the lines, patterns to match your company standards or OTB types and styles. Copy the cleaned-up version into your actual project or family. Avoid CAD files within a family.

  2. Graphics Issues after Linking or Importing CAD:  
  3. CAD Files Best Practices: 


When you export from Revit into CAD, there are 3 options of how to export the layers. 

The explanation given by Autodesk for these options are as follows:  
Export category properties BYLAYER and overrides BYENTITY. A Revit element with view-specific graphic overrides will retain those overrides in the CAD application, but will reside on the same CAD layer as other entities in the same Revit category.  
Export all properties BYLAYER, but do not export overrides. View-specific graphic overrides will be ignored in the CAD application. Any exported Revit element will reside on the same CAD layer as other entities in the same Revit category. By forcing all entities to display the visual properties defined by their layer, this option results in a lower number of layers and provides by-layer control over the exported DWG/DWF file.  
Export all properties BYLAYER, and create new layers for overrides. A Revit element with view-specific graphics will be placed on its own CAD layer. This option provides by-layer control over the exported DWG/DXF file, and preserves graphical intent. However, it increases the number of layers in the exported DWG file.  

Note: If you are exporting a view that contains a linked project and the RVT Link Display Settings dialog (Basics tab) for the link is set to By Host View, then the link is treated as an override. To ensure that colors and other graphic display settings are preserved in the exported file, select "Export all properties BYLAYER, but do not export overrides."

CAD Plotters 

By David Gerber - Support - A2K Technologies

Plot styles transfer over when you migrate your workspaces, however, there are times when you want to use someone else’s plot style or have a company-wide plot style that you would like to install onto your machine. 

This can be achieved in two ways: 

  1. Type in the command - “STYLESMANAGER” - in an open CAD drawing and the pop-up will automatically come up where the .ctb/.stb files are stored. 
    1. Copy and paste the files into this folder to install the plotter onto your CAD workspace. 
  2. You can go directly to the following UNC path and copy/paste the file there without the need to open CAD - C:\Users\%USERNAME%\AppData\Roaming\Autodesk\AutoCAD 20xx\Rxx.x\enu\Plotters\Plot Styles 
    1. Hint - Copy and paste: C:\Users\%USERNAME%\AppData\Roaming\Autodesk - in the Windows File Explorer to get to the AutoCAD 20xx folder faster. 

Errors Upon Launching Software 

By David Gerber - Support - A2K Technologies

If you launch your Autodesk software and get errors such as “License Manager Not Functioning or Not Properly Installed ” / “Licensing Error: Please Contact Autodesk Support ” / “Establish an Internet Connection ” / “ License Checkout Timed Out ”, it is more than likely due to updates. 

Autodesk released a Transport License Security (TLS) update back in August 2019. Users who did not update to the latest releases specified by Autodesk can experience licensing issues, as well as experience launching issues with their software. When/if it’ll happen is hard to know, however, it’s best to update to the latest as specified here:  

Have a look through that article and match your software and software version with their necessary updates. Cross-check to make sure you have all of the necessary updates necessary. 

We have seen this happen a lot on AutoCAD and Revit 2020 software in particular, but it does affect most software as well. 


Updates you will need for Revit 2020 (as an example): 

  1. Revit 2020.2 
  2. Autodesk Licensing Service - - Update  
  3. Autodesk Licensing Service (x64) - 5.1.5 Hotfix 1 


The first place we would recommend cross-checking is updating them all to the latest version either through: 

  • Autodesk Desktop App 
    • Download latest and it'll install automatically. 
  • Management Portal 
    • Go to - - under "Product Updates". 
    • Download and manually launch the installer to install. 


Windows Updates should also be double checked as some of them are necessary for the security updates of Autodesk software. 

  • Type "Windows Updates" in the Windows Search Bar to check for those.  
  • Could also have pending installs or restarts. If you have to restart, do so, then check again to make sure there aren't anymore. 

Usually it’s as easy as the above, however, in some rare cases, we have also seen some clients having to take extra measures for alleviating these errors. Autodesk has released the following article to solve the licensing issues:  

CAD Crashing 

By David Gerber - Support - A2K Technologies

If you have noticed that your CAD is starting to perform poorly or crash during certain tasks where it worked fine one day and not the next, this is usually easily fixed. Thankfully, CAD is pretty straight-forward in regards to what is causing performance issues. 


Usually CAD crashes are due to 3 things: 

  1. CAD needs to be updated. 
  2. Graphics Card needs to be update. 
  3. Windows pending installs/restarts. 


A question to ask yourself is: Is this only happening on one file or all files? 
If it's one file - Perhaps it's a corrupt drawing. As a test, duplicate the file, and try the following: 

  1. Open up a new CAD drawing 
  2. INSERT - insert your drawing 
  3. AUDIT - let CAD fix the errors 
  4. PURGE - purge unused items 
  5. Save 
  6. Retest 

If it's all files: 

  1. Which version of CAD is this on? Is it updated to the latest version?  
  2. Type - ABOUT - in the command line and send us a screenshot for us to cross-check it for you. 
  3. Is Windows Updated fully?  
  4. Type Windows Update in the Windows Search Bar to make sure there aren't any pending installs/restarts necessary. 

We highly recommend using the Browser Method as described here: 

Autodesk Install Media Browser Download

This tends to be the most reliable installer of the 3 choices Autodesk provides.

  1. If this installation fails, please screenshot the error you receive in the installation dialogue box as it'll help isolate the issue further.
  2. Please also go to your Windows Temporary Folder (type %TEMP% in the Windows Search Bar) and find/attach the file named "<software_name> Setup.log"
    1. Tip: Sorting by date will be faster in finding this file.

In some cases (Browser Method still failing), it may be worth using the Autodesk Virtual Assistant ( You can download the Autodesk Software in parts which is very handy.

  1. Once all parts are downloaded, launch the one named "001" and it will begin extracting the files and find the other parts automatically.
  2. Once extracted, you will find the files in - C:\Autodesk\<software_name>
    1. If the installer doesn't start automatically, go to the above folder and double click the "Setup.exe" file to run the installer.

If you have any errors coming up, please send them through to us at - - and we will help further troubleshoot for you.

Encounter any issues with your Autodesk Services product (such as the BIM360, or Fusion 360 product range) can be frustrating because the cloud is more or less out of our control. It's worth checking the Autodesk Health website to see if Autodesk have acknowledged a complication with that service, via the below Autodesk Health Dashboard;


If however there aren't any outages reported however, perhaps there's some other issue at fault, and if that's the case then please reach out to A2K Technologies support staff with details of your product and the error that you're receiving.
