With 1•2•Build, you can manage different calculation models side by side and save them together in a single file. The calculation models defined within the active 1•2•Build project can be accessed via the pull-out menu 
on the toolbar. You can use this menu to quickly switch between the various calculation models.
You can add a new calculation model to this list at any time using the icon 
. If you wish to give an existing calculation model a new, more appropriate name, use the icon 
and then specify this new name:
Copy model
An interesting application of 1•2•Build is the possibility to quickly compare the design of a beam in steel or in reinforced concrete using the copy-function. If you have for example a beam in reinforced steel, then you can copy the model using the button 
. You can immediately rename the copied model:
After confirming with “OK”, you have copied the geometry, support points and loads to a new model. You can now immediately design this beam!
Delete model
You can remove calculation models from the list at any time. To do so, select the calculation model you no longer wish to keep and remove it using the icon 
.
