I am trying to scale up a model but it is in 3 different parts. The way scaling works in MakerBot Desktop is that you change the exact lengths of the height, width and depth dimensions of the individual parts. Am i able to scale each part up by a factor of say 20% instead of scaling them by changing the exact lengths of their dimensions? Craftware has a feature where you scale the models by percentages, does MakerBot Desktop have a feature similar to this?
