Creo Parametric - Multibody Modeling and Flexible Modeling (FMX)

and creo parametric you can use multi body modeling in conjunction with flexible modeling and it's extremely powerful let's take a look at an example and I'm going to show you something similar to what Martin niemoller shows but I'm just gonna go a little slower so you can see some of the different picks and clicks let's start off by importing some geometry I'm gonna grab a step file that I have let's click the import button and then click OK and then hit the check mark out of here and so we've got the geometry import it's a little offset from my default tatom's that's okay let's just hide the ones that we have in the model for simplicity I'm gonna create some datums for reference like let's create a datum plane using this surface hold down the control can pick this other surface over here and that way I get a plane in the middle of the model let's just click the ok button out of here let's create another datum plane offset from this surface and we'll select the surface and then use the plane icon off of the mini toolbar let's change this to a value of 0.3 75 that's good hit the ok button and now with that datum plane selected let me right click to activate my mini toolbar let's create a datum axis at the intersection of that plane and the plane that I create before then click the ok button and this is just going to give me something to use as a motion reference in flexible modeling so what I want to do is take this part and I want to grab this side and let's say that needs to be rotated 15 degrees you can see that we've got a lot of complex geometry in here if all I had was the import feature it'd be pretty tough to do that but with flexible modeling and multi-body it's actually a lot easier let's start out by splitting our body I'll use be split command let's select our body which is the only body in the model for this floating object let's use this mid plane here then we have the arrow pointing to the new body that we're going through and up with and I'm happy with that let's hit the checkmark or middle mouse button and now if I expand the potties folder we've got body 1 which is the body on the right and then body 2 which is the one that the arrow is pointing towards okay so that's good I don't think I need these datum planes let's hide them real quick just to unclutter to the screen I can always bring them back if I need to you can see the scene where the bodies have been split now let's perform an operation let's select body 2 and we'll go to the flexible modeling tab let's use the Move command and it's got the body selected right now the origin collectors highlighted so I'm gonna select the axis that I created that's the reason I select I created in the first place and I'm gonna drag this and rotate it and let's make it let's say we need 15 degrees so let's double click on there and choose 15 over here and assume some thinking and then I can hit the check mark and so that way we've rotated our geometry you can see that we do have some issues over here with the overlapping geometry no problem we can take care of that let's start off by Oh actually before I remove them let's merge our bodies back together let's go to the model tab I'll just go to boolean operations it's automatically selected to merge let's select body 1 as the body to modify for the modifying bodies will choose body 2 and then hit the check mark or middle mouse button and again we can see that we've got some overlapping geometry over here let's take care of that by going back to the flexible modeling tab and I'm gonna select a bunch of surfaces here using the check mark and I'm just picking them manually over here and there few of them but not that big a deal grab those and the same thing on the other side where we've got some overlapping surfaces just a bunch of left mouse clicks with the control key held down and then from the mini toolbar I can choose the remove command it's the same command on the right hand side of the ribbon in flexible modeling and it's doing some thinking gives us a preview of where it's going to put it back together that's good let's hit the checkmark or middle mouse button and that seam looks good over there this seam over here looks good but right now we've got a gap in the geometry let me turn off my daemon access display real quick hey we can use the same remove command pick this surface over here hold down the control key and then just remove again there you can see a preview how it's filling in the gap and so in that way we did a really complicated operation using flexible modeling let's take a look at a another example let's say I want to just split this part and it needs to be longer well we can do that as well let me select a surface over here oops let me go back to the model tab now I'll select the surface now I can get to the datum plane command from the toolbar let me drag this over here let's I ball I come on beat on the other side of that hole over there now let's try value of 0.5 that's good let's hit the ok' button and once again we will use the split body command let me select body 1 by the way you can see that body 2 is still in the bodies folder but it is dimmed out because it has been consumed for the splitting object it's using the datum plane I must have had it selected when I clicked on the split body command so let's hit the check mark or middle mouse button and now let's select body 3 let's go to the flexible modeling tab let's use the Move command and I can select my datum plane as a motion reference I can say let's move this whole thing here let's move it let's say that we need this to be two inches longer I think this is an interest let's hit two over there and then hit the checkmark or the middle mouse button so now these bodies are separate even though there is space in between them we can still merge them let me go back to the model tab boolean operations and let's select body 1 as the body to modify modifying it with body to merge is selected on the dashboard let's hit the check mark or the middle mouse button so we have the body merge created and so even though they're separated their one body if we want to fill in the geometry in between them let's use a blend feature I'll go to the shapes overflow menu and then choose blend and for the first section I'm going to define it on this surface over here let's hit the sketch button I will use the project command to grab all the edges of the surface to do that easily I'll use the loop option and pick this surface over here for some reason the first pick you can't see the preview so usually what I do is click Next and then previous and there we see that it grabs the outside edges let's click accept out of there and this looks good I noticed that the start point is on the lower corner over here so I just want to make sure that that lines up with the next section that I create let's click close out of there hit the check mark and right now it's previewing a distance for creating the second section let's go to the sections tab and for section 2 instead of offsetting a distance I will use a reference let's make it through this surface over here let's click the sketch button once again I will use the project command and then use loop pick this surface here let me click Next and then previous that's good let's accept that looks like the start point is on the wrong cool so let's close out of that loop button let's grab that vertex right click and hold and choose start points and now the arrows on the right corner and hit the check mark over here and it previews the geometry let's hit the check mark and so now we filled in the geometry in between there so again we started out with imported geometry we did quite a lot to this we were able to split it rotate one half of it split it again and then filled in the gap in between there so lots of power and functionality that you can do with multi-body in conjunction with flexible modeling I hope you enjoyed this video for more information please visit
