The "tool" is whatever shape you want to cut out of the components. For example, extrude a shape in the assembly file and use assembly cut to "subtract" it from one or more components.
You need to either create a Solid Body representing the material to be removed or you need add a Component to the Assembly which does the same. That body/Component is then used as the 'Tool' for the Assembly Cut operation. Note that irrespective of what you use for the 'Tool' body, there is NO need to perform any sort of a WAVE linking or Promotion as that's taken care of automatically by the Assembly Cut function.
Also note that this 'Boolean' Subtract, or Cut operation, will only have an effect on the parts in the context of the Assembly as the original components will be unchanged by this Assembly-level operation.
Ok returning now with a new issue with this. I used this again and now I cannot get the tool not to show in the assembly drawing. Any ideas? Thanks
I do have hide the tool checked on the dialogue.
Is the tool in the Reference Set which you use in your drawing? When you use layer, check if the tool Layer is visible in your view (Format -> Layer Visible in View?)
Thank you sir I will give that a shot. Though I must say I would think it would do this in the dialogue when you check to hide tool. Ah well.
