Assembly of subassemblies relations

[TuxedoCat]

im trying to make a relation in an assembly between 2 sub assemblies. tried to do as written in the website, but cant see the session id after enabling it.

i had a master part, that i created parts from it, then assembled those in 2 sub assemblies.

it calls the parts 'extern copy of id'.

Hi,

your description is not sufficient. Please create test assembly and upload it as an attachment of your next reply.

in this example i have a subassembly (asm1) made of 2 parts created from a master part (p1_prt1 and p1_prt2 created from p1), and another part p2. i created an assembly asm2 made from asm1 and p2.

asm1 have a cylinder and p2 a hole. how can i make a relation between the two radiuses in the asm2?

Hi,

you files were created with an educational version of Creo Parametric. Therefore I cannot open them in commercial version.

Option 1: Start new discussion in https://community.ptc.com/t5/PTC-Education-Forum/bd-p/PTCEducation area.

Option 2: Publish pictures of Creo window with appropriate notes. This enables me to recreate your test data.

p1:

p1_prt1 (created from p1): 

p1_prt2 (created from p1):

p2:

asm1 (made from p1_prt1 and p1_prt2):

asm2 (asm1+p2):

how can i make a relation between the two radiuses in the asm2?

Hi,

I do not understand why you use External Copy Geom.

See simple example in my video.

[TuxedoCat]

i was told by my teacher to create parts from each body from the master part (like in the pic), in order to assemble them in asm like in real life. it automatically creates an External Copy Geom when i press it

i saw the video and understand i need it as a real part and not as External Copy Geom, but i didnt find a way to do it from the master part like the teacher requested

Hi,

second video attached.

[TuxedoCat]

my problem is that the dx:y doesnt show,

in the video u chose p2 (part) and not p1 (sub-assembly).

in mine i have 2 sub-assemblies and when i choose a part from the External Copy Geom it doesnt show dx:y other then a 0-valued one (i think its from a sketch for a dtm plane)

so i tried changing the look in to part: 

but it still wont show dx:y other then the 0-valued one

(i apologies if the video doesnt work)

Hi,

I still don't understand what the teacher wants from you. I think you should clear it up with him.

From my point of view, you have 2 "options".

Option 1.]

Create all assembly components as standard parts (single body) and assemble them according your needs (2 subassemblies, 1 main assembly). This method enables you to define relations in main assembly and use dimensions defined in parts.

Option 2.]

Create single parent part (multibody) ... every "component" in separate body. This method enables you to define relations in parent part. Then apply Create Part from Body to every body. At the end assemble these parts according your needs.

Option 3.

Use EXECUTE STATEMENTS and INPUT PARAMETERS to drive parts and/or subassemblies from a main assembly.
