Creo Parametric - Import Tricks | Import Data Doctor and Flexible Modeling Extension

in creo parametric there are some tricks that you can use when importing step files in order to get exactly the geometry that you want and I mentioned in my video on universal joints how I did some tricks when I was creating the components from a step file that I downloaded from trace parts for this commercial universal joint let's take a look at that so let's say I want to open the I just file or excuse me the step file I will go to the folder that contains it here is the step file and if I just click on the import button I'm automatically going to get an assembly I'll click OK and here's what I got this is pretty good for some reason a lot of times when you import a step file you get an additional assembly level here sometimes I'll just work on that one and not use the top level and most of the components here are pretty good so for example there I've got one component there another component over here but when it came to the cross and the bearing caps let's say I wanted these all to come in as one single component rather than individual components because this could end up being a little complicated when I'm working on my mechanism so instead of using all these different parts here what I did was I took this part and I saved it and also this part over here but let's take a look at another way of importing the crosses as just individual components this time I'm going to start off by creating a new part and for the sake of this demo I'm not going to change the name of the part and I will use my default template now that I've got the part started let's import the step file and there it is and I'm using my profile which I showed how to create in another video let's click the ok button and here is all the geometry brought in the entire step file as a single individual part but rather than just hitting the check mark here I'm going to use the import data doctor in order to get rid of everything except that opponents that I want is part of the cross when I go into the import data doctor you'll notice that it grouped a lot of the geometry of the different surfaces and solids as these individual components so what I can do is select the ones that I don't want and get rid of those components I'm gonna start off by selecting these and let's right-click and then choose delete and so now I've just got two of the crosses I'm gonna keep this one over here it doesn't really matter which one I keep but I happen to know that it's a few of these different other components over here that I don't want so let's delete those and now I'm down to just five components that were imported as part of this step file this is good let's hit the check mark and the check mark again so now I've used the import data doctor to just leave me with one of the crosses that's good so far let me show you another trick I'm going to turn on my datum plane display because of where it was located in the step file it's located offset from front and right and this is okay but sometimes you might want the geometry located centered on your default datum planes if you want that you can use the flexible modeling extension in order to do that we're going to use a command from the Move command called move using constraints we far go in there I'm just gonna select all the geometry in here now I will use that move using constraints command and I can move this over using my different placement constraints the problem is though right now I don't have a plane inside of this geometry so while I'm in the middle of this tool if I go to the datum drop-down menu over on the right hand side I can create a datum plane while I'm in the middle of this command so let's select one surface right now it wants to offset at a distance I mean hold down the control key and select this other surface and now I'm ending up with a mid plane between those two surfaces that I can assemble to the datum plane called front let's click the ok button out of here I will resume the dashboard and the thing is right now it's using that datum plane as the stationary geometry so I'm gonna right click here and choose remove and so that way I can select hey I'm using the datum plane front as my fixed geometry let's go to the references tab and I'm gonna click in the collector for move curves and datums and select that datum plane that I just created inside of the feature now let's go back to the placement tab and I'm going to select as the moving geometry item that datum plane that I created as part of the geometry right now it's giving me a distance constraint let's change that to coincident and so there you can see the preview so that's pretty good now I want the middle of this part aligned with the datum plane called right so I need to create some more geometry let's go to the datum drop-down and I need an axis in here you'll notice when I get in here the preview goes away and the original geometry shows up over here let's create the axis through this surface over here that's good now let's create a another datum plane now hold down the control key and select DTM one is the reference and offset 90 degrees or you could use the drop down and say that we want it to be normal either way I'm getting a plane here that I can align to the datum plane called right now let's resume the dashboard again I'm gonna go to the references tab and click in the move curves and datums collector and hold down the control key so I can select DTM - so now these two datum planes that are created on the fly are part of this geometry let's go to the placement tab and again it's using that datum plane that I just created as the fixed geometry that's not what I want - let's remove it from there the fixed geometry is actually going to be the datum plane called right and for the moving geometry I'm gonna select that datum plane that I just created and so right now again it's suggesting a distance constraint no problem I can go to the damn listen choose coincident and now I'm going to get the geometry exactly where I want it to be when I hit the checkmark now you'll notice that it has updated the geometry and my imported geometry is right in the middle of my default datum planes now also on here you can see that we have a few datum planes on top of each other when you perform the move here the datum that created on the fly but it also created a copy of those planes as well to turn off their display I'm going to use layers and normally get two layers from the view tab but it's a command that I use so often that I put it in the quick access toolbar and also when you import geometry a lot of times you're going to get a bunch of layers created automatically usually I delete these layers be aware that deleting layers does not delete the contents of the layers and here I have my different planes in here let's create a new layer and I'm not going to bother changing the name let's use the selection filter in the lower right hand corner to change this to plane to just make sure that I'm selecting the copies of the datum planes that were created that's good click the ok button and hide the layer let's repaint the screen and that way everything looks beautiful I've got my imported geometry located at the intersection of my default datum planes so again those are a couple different tricks that you can use with imported geometry using the import data doctor to delete unwanted components and also using the flexible modelling extension specifically the move using constraints command in order to position the imported geometry exactly where you want it to be I hope you enjoyed this video for more information please visit WWE and chill comm if you learn something from this video please give it a thumbs up and if you like
