Hi,  
I just went through the Tutorial Videos and started to build a new mvd( loaded the ifcdoc file ,added a new mvd and data exchanges). when I am going to entities to add them to the corresponding mvd by right clicking on them, I just get “Insert attribute” option, not the “Assign model view” option that appears in the videos.  
Can any body give me a hint of what I am doing wrong,please?  
Bests,  
Kaveh

Hello Kaveh,

the tutorial videos are kind of outdated in the new versions of the IfcDocTool entities are added differently than in the videos.  
When you added a new mvd under Scope right click it -\> insert -\> Table Definition  
After you added it you can name it as you like. When you left click on the new Table Definition you can see a window on the right side saying “Double-click to create mapping.” Follow this instruction and you can add any IfcEntity.  
To understand the tool better, import a baseline definition and study the predefined MVDs and see how they accomplish things.  
I hope this helps.

Best regards  
Tobias
