Why is Allplan running so slow?
Check the following points:
1. Current version
Make sure you work with the current Allplan version.
- Do the following or ask your system administrator to do this:
Open Allplan and click the ‘?’ icon in the upper right-hand corner. Click ‘Update Allplan’.
Select 'Find now'. If Allplan finds updates or hotfixes, download the installation packages.
- Deactivate the virus scanner while your are installing updates or hotfixes. This might require administrator privileges. Contact your system administrator if you have problems.
- Right-click the Allplan icon on the desktop. A shortcut menu opens.
Select ‘Run as administrator’ and click ‘Yes’ to confirm the following message.
As a result, Windows security settings do not block the installation.
2. System requirements:
Check the hardware and software required for your Allplan computer.
2.a)Download and run the system test.
Check the notes.
2.b)Check the Allplan system requirements:
2.c)You can find information about graphics cards at
2.d)You can find server operating systems you can use for the central file storage of Allplan at
3. Hotline tools:
Start the Services application, open the ‘Service’ menu and select ‘Hotline Tools’. To save your settings, select the following tools.
- savestd: Saves user defaults.
- savereg: Saves CAD registry settings.
Start the Services application, open the ‘Service’ menu and select the following ‘Hotline Tools’:
- cleanup: Initializes the display.
- cleanstd: Resets CAD defaults.
- cleanreg: Resets CAD registry settings.
Check whether this has solved the problems.
If this is not so, restore the settings you just saved. To do this, start the Services application, open the ‘Service’ menu and select the following ‘Hotline Tools’:
- reststd: Restores saved user defaults.
- restreg: Restores CAD registry settings.
4. Color scheme selected in Allplan:
Start Allplan, open the ‘View’ menu, point to ‘Toolbars’ and select ‘Customize User Interface’. Open the ‘Customize’ tab and set ‘Color scheme and icon design’ to ‘Windows’.
5. Check the availability of all projects that are not online (if you use Workgroup Manager):
Start Allplan, open the ‘File’ menu and select ‘New Project, Open Project’. Deactivate ‘Check availability of all offline projects’.
6. Virus scanner
Check whether an anti-virus program is running in the background of the computer or server.
If so, reduce protection to "programs only".
Scanning "all files" can take a long time, considerably slowing down your computer when you switch between projects or exit the program.
You can exclude the Allplan installation folders from real-time scanning.When you start the Services application, you can see a list of the folders to be excluded.
You can find more information at
Changes in the settings of the virus scanner only come into effect when you re-start the computer.
7. Aero desktop effects
Deactivate the Aero desktop effects of Windows.
To do this, open the Control Panel, select ‘Ease of Access’ and go to the ‘Make things on the screen easier to see’ area.
Select the ‘Turn off all unnecessary animations (when possible)’ option.
8. Name resolution on the network
If Allplan takes several minutes to start, name resolution on the network may not work.
To check this, do the following:
Right-click the Windows Start Button, select ‘Run’, type in ‘cmd’, click OK, type in ‘Nslookup’ and press ENTER.
Go to the line following the > character, type in the name of the Allplan data server and press ENTER.
The reply starts with the name and address of the server providing name resolution.
You can find the name and address of the Allplan data server in the second group.
If problems occur, contact your network administrator and ask him or her to configure name resolution correctly.
9. Speed of Allplan projects
Check whether some Allplan projects are slower than other Allplan projects.
Start with the empty project and check whether it is slow too.
After this, select any other Allplan project.
If it is only the current project that is slow, the problem may be caused by the data of the current project.
In this case, the data of this project must be analyzed in detail.
Contact technical support.
10. Network: checking out Allplan using Workgroup Manager
If you use Allplan with Workgroup Manager, you can check whether the problems are caused by the network. To do this, check out the workstation with the project in question and use the project on the local Allplan workstation.
You can find detailed information on checking out an Allplan workstation using Workgroup Manager in the
Services application. Open the ‘Help’ and select ‘Workgroup Manager’.
After you have checked out the workstation, Allplan no longer accesses the central file storage of the server.
If this has solved the problems, they are caused by the network. In this case, the network must be checked in detail.
Contact your network administrator and ask him or her to do this.
If the project is still slow, the problem may be caused by the data of the current project.
In this case, the data of this project must be analyzed in detail.
Contact technical support.
11. Log files and system information files
If all the points above do not solve the problems, technical support requires more system information about the computer running Allplan.
- So, we would be grateful if you could send us a support request (Allplan Hotinfo with Allplan logging).
To create a support request, start the Services application, open the ‘Service’ menu and select ‘Create support request (Hotinfo)’.
Several dialog boxes open. Select ‘Technical Support Allplan’ and ‘Enquiry with Allplan logging’. Enter all the data required. Finally, click ‘Finish’.
Another dialog box opens, prompting you to start Allplan. Click the ‘Start Allplan’ button.
Allplan starts, logging all processes.
Try to reproduce the problem as exactly as possible.
Exit Allplan as soon as possible, reducing the data in the log file to a minimum.
Then click ‘Next’ to generate the support request with the log file.
You can find more information about Hotinfo at
- To analyze the Windows system environment, we would ask you to send us the logs created by Windows Event Viewer of your computer.
To start Windows Event Viewer, right-click the Windows Start Button, select ‘Run’ and type in ‘eventvwr.msc’.
You can also type in ‘Event Viewer’ in the search box of Windows. This displays the link file to the Windows event logs.
Using Event Viewer, create *.evtx files for the application log and the system log in the ‘Windows Logs’ area and for the ‘Administrative Events’ log in the ‘Custom Views’ area.
