Primitive Add/Substract

Recommended Posts

I am trying to clip the edge of a rafter look-out detail using primitive solids.  When I use the "solid intersection" I can't seem to control which section cuts which.  Is there a way to control this?

 

Here is a pic to illustrate.  I set the cut piece to glass.

Thanks for the info - so I can't just freely control what object "cuts" and what object stays in the operation?

 

I ended up just drawing the piece I needed in the section/elevation view.

Johnny,

 

1.  Select the Object you want to cut

2.  Select the Solid Subtraction Tool on the Edit Toolbar

3.  Select the Object to be subtracted.

 

Both objects have to be the same object type (either 2 Primitive Solids or 2 Polyline Solids).

There are 3 Tools:

  Addition --- combines 2 Solids into 1

  Subraction --- removes the volume of the 2nd from the 1st, leaving only the remnant(s) of the 1st.

  Intersection --- creates a surface where the 2 meet, deleting both objects

 

I like to do these operations using a Plan and 2 Elevations or a Perspective View.  Positioning the Objects is the key.

See, Chief does have some capabilities - even if they are not immediately intuitive.
