INVERT OBJECTS

Postby scdrawert » Mon Dec 17, 2018 8:24 pm

Dear Community,

my plan is to create items in SketchUp which i want to product from modelling concrete. In order to do that i need the "negative" of this item and send it to a 3D printer.

i.e. i want to make a cylinder -> i need to get a cube with a cylindric hole inside - clear i guess.

My question - is there an easy way to generate NEGATIVES or INVERT my objects in Sketchup? becuase some of the items simply get too muss to translate them in my head into the respective negative form.

Maybe someone can help me with a hint or a plugin?

Cheers guys

As you have the Pro version, seems that you can make that you want with the "Booleans" functions! ;)



even better for pro or not Pro

free to you to Union the 2 boxes at the end if needing... :ugeek:
As alas (in SketchUp) you can't use boolean function with a volume completly inside another one
you must uses 2 "boxes" from the start! :ugeek:
