Creo Parametric 7.0 - Multibody Modeling - Construction and Subtraction

in creole parametric you can use multi-body modeling for construction and subtraction let's take a look at that here i have a part model i've already got a sketch inside of here i can take this sketch and then choose extrude from the mini toolbar let me right click over the depth drag handle to change this to symmetric maybe i want this value to be 12 instead that's good let's hit the check mark so right now i'm just doing some standard part modeling let me throw some fillets in here i tapped the right mouse button when i hovered over the edge in order to get the intent edges the edges associated with the feature and i can choose to put in some rounds from the mini toolbar i will take that value that they are suggesting so right now all i've done is created some part geometry now i want to use another part for modifying this part let me hop over to my other window i want to have this particular component mounted on that part in a certain way and i want to subtract geometry so it fits in there exactly let's take a look at how to do that let's go back to the other part window over here to bring in that geometry i will use the merge inheritance command i'll click on that and then for the model that i want to use let me just grab that part from in session here we have the component placement dialog box for locating it let me click on the eyeglasses icon so i can see a preview of where it's going to wind up for the first constraint let me select this surface over here and that surface over there to make them coincident the next constraint let me choose this datum plane come here and this datum plane from the part let me choose the flip button that's good and for the last constraint let's do a distance constraint from this surface to this surface over here right now it's giving me constraints invalid let's try flipping it's giving me a distance of zero let's try value of four let me try negative four there we go i like the positioning of the component let's hit the check mark out of the component placement dialog box and when i take a look up over here oops let me turn on my highlighter when i take a look up here now in creo parametric 7.0 you have four different choices for what you want to do with this geometry you can add bodies you can add material you can remove material or you can intersect material in this particular case right now we are choosing to add bodies i can choose to add material instead now the body options tab becomes available instead of adding it to body one i can choose to create a new body and there you can see where it is going to name it in there that will be its own separate body let's go to the properties tab i always like to change the name of the feature to reflect what it is now we can hit the check mark if you take a look in the model now it brought in the geometry in there we have body to over here and it's automatically set as the default body so any new solid geometry would get added to body two instead if i don't want to do that i can select body one and then use the set as default body icon from the mini toolbar furthermore i want to use that merge geometry as construction geometry so instead i can select body 2 and then right mouse click and set as construction that way this geometry that was brought in won't contribute to the mass properties and also won't be considered as a body if i was do a drawing and create one of those body tables also won't be used in any interference checks and now i have that as construction geometry i could make other features around this using that different geometry as a reference and also i can perform boolean operations with that body now again i could have subtracted when i created the merge inheritance feature but i just added as a separate body in case i wanted to create new features around this particular one before i move on let's turn off our datum plane display if i actually want to subtract that construction geometry i can go to the boolean operations command for the body to modify i'll choose body one and right now it's choosing to merge i can change that to subtract and for the modifying body i can choose body two over here you can see a preview of the geometry that's going to be created here's the option to keep the bodies now let's say that i do want to do that let me choose to keep the bodies then i can hit the check mark out of here and so it's performed these uh subtraction i can still see body too but i can just hide that now you can see how it's made this nice little cut inside of here the way that i want it to be created might need to trim off a little other geometry in here looks like i've got an extraneous body over here hey no problem we can go to flexible modeling select this over here and use the boss shape surface selection tool and then after that i can choose to remove this geometry over here hit the check mark oh looks like add another one over here let's repeat that process use the boss selection tool and then just choose remove from the mini toolbar so in that way i'm using that imported geometry to remove stuff and again it's just hidden right now i can always bring it back make it visible it is construction geometry so i can use this for designing other features around it so there you see a bunch of different techniques for multi-body modeling including merge inheritance into a new body and then doing some boolean operations and then incorporating some flexible modeling i hope you enjoyed this video for more information please visit www.creowindchill.com if you learned
