Hollow blue thread

tj_thornileytj_thorniley Member Posts: 65
Just wondering why this thread I made is blue, unlike the rest of the object. And why it doesn't have a solid face that I can sketch on for the final extrusion.

    @tj_thorniley :

    The part is a different color because it is a separate part (it is not geometrically connected to the brownish part).  This is probably due to using 'New' instead of 'Add' in one of your features, but it would be easier to figure out if you posted a link to your document.

    If the parts are currently touching and you would like to join them, you can use the 'Boolean' feature with he 'Union' option.  If they are not currently touching, you will need to connect them geometrically before they can join to become the same part.

    As for your second question, you must use a planar face or construction plane for a sketch.  If the geometry you've created doesn't have a planar face to define a sketch plane with, you can use the 'Plane' feature, which can create a construction plane based off of a number of different combinations of geometry.  You can then sketch on this construction plane.

    @Jake_Rosenfeld I ended up just redrawing that part and it was all good. I'm pretty sure I always use 'New' instead of 'Add' though. Or whichever is usually the default. Thanks for the advice though, I'm making progress.

    The boolean options along the top of the features actually have some smartness built into them based on the selections you make. If you make something that doesn't touch anything else it will go to 'New', but if you start an extrusion that touches an existing body it will try to automatically change to 'Add'.  Of course, you can always override the guesses we make manually.

    Good to hear about the progress!
