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.

How can Allplan be operated under a QHD / UHD / 4K resolution?
Starting with Allplan 2018, a query will appear in the Allplan Start under a QHD / UHD / 4K resolution (from 2560 x 1600), in which you can decide whether the operating system scaling should also be used in Allplan. This choice can be changed at any time in the Allplan Options-> Desktop Enviroment- > Display-> Scaling of the user interface.
If this option is switched on, Allplan uses the scaling level, which is set globally in the display settings of the operating system. Side effects of this scaling can be slight blurring in the symbols, drawing elements, and dropped graphics in Allplan.
Please note that this functionality is only available from Windows 8.1 and higher.
You may ask yourself on which occasions or user actions Allplan synchronizes drawing files and plans with the Bimplus Cloud in an Allplan Share project.
The following cases apply to drawing files:
Drawing files in a share project are uploaded to the Bimplus cloud for synchronization if all three of the following conditions apply:
- A change has occurred on the drawing files
- The drawing files have been changed to gray or deselected
- Open on a project-specific basis is closed
Download PDF FAQ_EN_When_do_Allplan_share_projects_synchronize_dr...
If other users have the drawing file which meets all the criteria in case one, grayed out (i.e. it is passively in the background), then after the first user has carried out all three steps, they will automatically receive a message informing them that there have been changes to the drawing file. They can then either display or reject these changes.
If the other users do not see this message, they should make sure that they are using the latest version of their Allplan installation and that the check mark is set in the options for Options -> Desktop Environment -> Save/Load -> For changes in reference drawing files show message. If the check mark is not set, simply set it and restart Allplan.
In Allplan, click on Allplan A in the top left-hand corner and select Save all -> all drawing files that have changes are synchronized.
In this case too, as in case 1, a message is sent to all users who have the drawing file, to which all the criteria from case 1 apply, in grey (i.e. passively in the background).
Even if you simply open the function New project, Open Project, all drawing files that have been modified are synchronized
When you call up the Layout Editor, all drawing files that have been changed are also synchronized
The following applies to plans:
If drawing file contents in the plan change, then the plan is NOT uploaded - no need . Plans are only uploaded if either something changes in the plan layout (move or delete a plan element in the plan, etc.) or, for example, the scale or drawing type of a plan element is changed. The upload then takes place automatically when you change the plan or leave the plan layout.
In Allplan version 2018, these notes also apply accordingly; only case 2 for drawing files does not work in this version.
When I create a hidden line image of an isometric view (Viewmenu -> View-> Front Left, Southwest Isometric Viewor any other isometric view), Allplan does not use the original dimensions so that the resulting lengths are distorted.
How can I make sure that Allplan creates the hidden line image based on the actual dimensions?
In accordance with DIN, an isometric view is calculated as follows:
Allplan chooses the projection plane and the axes so that all the axes are shortened equally = axonometric projection of an isometric view.
This is the case when all the angles are the same: 120 degrees. The result is an equilateral triangle. Each side is shortened by two-thirds or 0.8165. However, the edges parallel to the axes are usually not shortened.
Angle of the coordinate axes:
x axis: 30 degrees to the horizontal
y axis: 30 degrees to the horizontal
x : y : z = 1 : 1 : 1 (using a factor of 0.8165)
When calculating an isometric view, Allplan shortens all directions by the same value (x:y:z = 1:1:1), using a factor of 0.8165.
All you need to do is resize the result in the destination drawing file by the corresponding factor (1.22475) in the x and y directions. After this, all the edges are displayed at their actual size and can be dimensioned.
How can I use Allplan to create PDF documents (Portable Document Format) that can be opened and viewed using PDF viewers such as the free Acrobat Reader?
You can export PDF files directly from Allplan.
In addition to the design, bitmap areas and text, the direct export tool transfers layers, OLE objects, transparency and gradients.
Of course, you can also use external programs such as Adobe PDF and FreePDF to create PDF files. However, these programs do not provide all the options mentioned above. For example, transparency is not transferred.
Allplan provides the following options for exporting PDF data:
1. using the layout editor:
Create -> Plot Layout -> Export PDF Data
2. using the print preview:
Click the Export PDF Data icon in the toolbar at the top
3. exporting 3D PDF files from the animation window:
You can create a PDF file from the animation window. This file contains the 3D model displayed in the animation window.
This option is not described any further in this FAQ.
When exporting PDF data, you specify the file name in a dialog box, where you can also make basic settings for the PDF file:
- Resolution (in dpi)
- Document size (paper size (with margin) or printable area (without margin))
- Entire layout content
- Archiving format PDF/A 1a
- Export layers
- Embed TrueType fonts
- Add to file (first select an existing PDF file in this dialog box and then select this option -> the PDF file is attached as a new page to the existing file)
- Grayscale (version 2011 and later)
- Open file with associated application (should be selected. After you have created it, the PDF file automatically opens in this application so that you can check it.)
Note on the page format (new in Allplan 2011):
In Allplan 2011 and later versions, you set up a page in Allplan. The page size should be used as the size for the PDF file.
You need to exactly define the size you require for the page.
To use the page size for exporting the PDF file, select the following options:
- Select 'Paper size (with margin)'.
- Clear the 'Entire layout content' check box, if necessary.
Notes on 1. settings in the Plot Layout module:
You can make advanced settings in the "Plot Layouts" dialog box.
The following settings are used for exporting PDF data:
- Plot elements / options (Selection tab)
- Paper format and orientation (Output tab); see the above notes on the page format.
- Resizing: Resizing factor, resize pen thickness and rotation by 90° (Settings tab)
- Pen and color assignments... (Settings tab)
-> Line thickness for monochrome output and line colors for color output
-> Line display in color, black or using shades of gray (can only be changed when you select a color printer beforehand)
-> Gamma correction
- No pen optimization/ Use one pen only (number:)
- Plot profile (Settings tab)
Download PDF FAQ_EN_Creating_PDF_files.pdf
Notes on 2. settings in the print preview:
The PDF file is exported as it is currently displayed on screen.
You can make the settings that are used for the "Print" tool directly in the print preview (Display tab in the Print Preview Options).
To export PDF data in color, you need to install a printer driver that supports color and select this driver in the layout before you start exporting the PDF data.
It is advisable to install a printer driver for a large-format color plotter such as an HP DesignJet even if your office is not equipped with a large-format printer/plotter.
[Install as a local printer/ without plug & play, port: FILE, do not share the printer, do not print a test page.]
