Sort multiple columns

Have you ever been sorting columns over and over in reverse order to in the end get the grid sorted by multiple columns? Occasionally one has a sorting and want to freeze the current sorting and apply a second subsorting. 

Hold down Shift and click on the additional columns you want to sort, and they will be sorted in order from most significant, second, third and so on. 

Objects ordered by Byggnadsplacering, Processfunktion

Ctrl + Shift + K 

This command can be used in grids and will perform the following actions. All fields/columns without any data are hidden. The width of shown fields is set to best fit, adjusted according to the widest data. 

Example scenario: Empty cells marked with pink. Unless we were inspecting of those specific fields were empty or not the view give us little information. Are all fields to the right empty? Are all rows below empty? 

Notice the size of the scroll bar. It is representative of how much data is shown out of the data loaded to the grid. When using the shortcut Ctrl+Shift+K the grid focuses on the non-empty cells. 

Managing Service Interruptions

This article outlines procedures for intentionally restricting user access during system downtime such as an upgrade.
Please note that the instructions provided are relevant specifically when using network licenses.

Initiating a Service Interruption 

To lock users out during a service interruption, follow these steps:

Open any web browser.

In the address bar, type the name of the machine where the license server is running, followed by port number 5054.

The web interface for the Reprise License Server Administration will appear.

Click on “Shutdown.”

On the displayed page, you have the option to shut down ISV processes, which manage the licenses themselves.

If RLM is used for multiple licenses, select “vendor license idesglobal” from the ISV list.

Next, click “SHUT DOWN SERVER” to deactivate the server. This action affects the ISV. For your information: RLM remains operational, and you can use the same web interface to restart license management later.

Ending the Service Interruption 

When you’re ready to end the service interruption and allow users back in, perform the following steps:

Open any web browser.

In the address bar, type the name of the machine where the license server is running, followed by port number 5054.

The web interface for the Reprise License Server Administration will appear.

Click on “Reread/Restart Servers.”

On the “Reread/Restart Servers” page, you can also choose “idesglobal” from the dropdown list.

Then click “REREAD/RESTART” to read the license file and start the ISV server. For your information: The same button is used to load the new license file during license extension.

Fill upp

Hold Ctrl to access Fill up 

By holding Ctrl as modifier when opening the right click menu Fill down is replaced by Fill up. 

Could come in handy when filling large amounts of ordered data and want to use a fill series without having to scroll to the top between each filling.  

Invalid Class String


When the process is being run with administrative privileges the user is unable to get Elmaster Design started properly.


Error messages at start of Design that says Failed to load Master Concept dlls and invalid class string.


To make it possible/easier to switch between parallel installed versions resources are registered during the initialization of the application. The registration is done for the user who is logged in.

If the application is run by another account – even if that account has high privileges – the part of the registry being used is not the same as where the references to the resources have been set up.

It is a limitation that the acad.exe process about to load Elmaster Design must be run by the logged in user.


To confirm if processes you initiate are being run by your logged on username one can often determine by opening a command prompt and looking at its title bar if it says administrator or not.

Another way to determine if you have this problem is by looking at the acad.exe process via Task Manager. Go to the information pane and select the columns to show via the context menu on the column headers. Choose to show elevated privileges. If your acad.exe process is running with elevated privileges that means it is being run as the administrator account.


If you are using the context menu on the icon and Run as Administrator – don’t.

Instead run in normal mode by clicking on the icon in start menu och double click on the desktop icon to start Elmaster Design.

Usually, this problem occurs when the user temporarily gains elevated privileges to install new software. Via policy or similar management, the processes initiated by the user are impersonated and run by the administrator account for the duration of the installation period. If that is the case, let whoever gave you the elevated privileges know when you are done. When impersonation ceases, the problem ceases.

Preventive measures

Avoid running the acad.exe processes as administrator. Run it as your logged on user.

If users are temporarily given local administrative privileges for installing software, it is advisable to plan ahead and schedule the installation at a time when the user is not supposed to be productive using Elmaster Design.
