Hello! So I have a big problem. Currently, I am using creo parametric and my assignment is to build hoisting gear. Right now I am at a stage where I assemble components. Which means I also download certain cad models or components from online websites (skf, part community, etc). My problem is the component that I have downloaded is somehow faulty? It lacks information, for example, does not have any axis, the unit is not in mm but in inch, and much more. Fyi, I just did the same things (like everything side by side) as my friends did and when I compared our model properties, mine is problematic and very different from theirs. This cause so much difficulty and stress to me. Please help me to fix this problem. Thank you!
If this is 'your assignment' I am guessing you are a student and therefore YOU need to do your own work and discover why your models are different. Creo allows you to model in inch or mm and convert between the 2 systems.
First - congratulations on using Creo in your studies. There is nothing wrong with asking questions about a resource that is available to you. Out here in the "Real World", we also download lots of things rather than creating them from scratch. You need to learn how to make them useful to your projects.
As far as things missing from your import and proper units: If you select "Use Templates" (a little check box in the Profile section) when you start your import, the software will use your default start parts while importing the object. You may have to move some stuff around - like the center axis - but it will be closer than if you didn't.
If you still need to change the units, go to File>Prepare>Model Properties then change the units.
If no center axis or planes were imported, you can "roll back" the model (Insert Here) to the appropriate place (just before the import) and insert the axis there (also the 3 default planes if needed.)
I hope this helps and is not too late for your assignment.
