problem adaptation parts

[Fede79]

Bye to all,
I apologize in advance for the "banal" problem that I will go to put ... forgive me I am at first arms and for a little last night I did not hammer the pc!
use inventor 2010 proffesional in Italian.
Can someone explain to me how to relate two parts placed in a set?
You know, I'm pretty sure I'm gonna change one, and the other should be "follow" right?
I did this simple test:
-created first part a cube 100mmx100mm (from its sketch completely bound)sed on the corners.
-created second part in sheet made to "c" (from its completely bound sketch) with internal size 100mm and 25mm.
-created a file together by placing as first part (fixed) the cube and second part "c" sheet binding (co incident) internal face of the sheet with upper face of the cube, then I bound (co incident) the inner face of the 25mm flap with the side face of the cube and same thing for the other flap.
Now if I change the cube by bringing it to 200mmx200mm the "c" in sheet that is practically like a hood above the cube does not stretch ... when I press on upgrades signals the error that the constraints are in contrast and you have to eliminate one.
because the "c" in sheet metal does not fit the cube... where I mistake...
Help me please ...

You're talking about "adactivity."
When you create the part that you have to adapt, you have to leave without quotas in the sketch, the size that you will have to adapt, then you have to tick to that processing the "adactivity" flag.
When you insert this part into the axieme, even here, you'll have to poke that part.
and anyway, especially for folded sheets,inventor is a little woody for the adage: It doesn't always work.
But since you have 2010, you could use the multibody, i.e., take the two parts as independent bodies in part and then drift them. I do so often; it's safer and more debriefing.

Hello tarkus,
Meanwhile thank you for the answer.
I tried to leave the sheet without quotas in the sketch and I also set adactivity on the sheet both in the part and in the axieme but the error is always the same.. .
as you say I created the parts as independent bodies in the environment parts but I don't know what you mean by multibody and then derive them.
I create a new file together and from there I place first the cube and after the sheet... is it wrong?
Could you explain your methodology better?
Thank you in advance.

when you create a solid,both for extrusion,revolution,specking etc., in the dialog box there is the "new solid" button.
with that you create independent bodies.
you also create a list of solids in your browser.
This is the multibody.
If you want to have files with every solid you have created, you have to derive them.
go into management->create part.
here choose the solid(s) you want to derive the words with which model (lamiera,parte) you want to create it and which name will have to have the file and if you want to insert it into an existing set or not.
at this point you have your .ipt components that you can use as you want, but that are linked to each other in the source file.
if you want to change a part you will do it in the source file.
if you make your change to a solid, it also modifies the other solid that you built on it; obviously if you have bound the geometries of the parts during their construction. ...
test:biggrin:

I forgot, after every change in the original file, to see the changes in the derived files, remember to click on "upon". .

Okay, I'm trying tonight with the method I'm saying...
only one clarification, the button of "solid new" I have to press it inside the environment together right and there I create first the cube and then the sheet above ... binding it to the cube.
Thanks again and excuse me for these banality, but I'm at first arms and I'm twisting my brain ... a friend who uses solidworks had made me see the procedure and seemed so easy and obvious the adaptation of the parts.. .

no,no,it does everything in one file in the environment part; together we talk later.
Open a part file that will then stay as a base file.
- Make yourself the first solid.
-you create the second with a geometrically bound sketch to the first (project geometry of the edges of the first and viculate your sketch entities to these).
when you go extrusion/revolution/sweep etc of the second solid sketch, you have to click on the cube icon with the star on the edge,
e.g. in the extrusion command is the one under the three icons of the extrusion type.
so you create a distinct solid from the first.
In fact, in the browser, immediately after the file name, next to the "solid frames" node, the n° 2 will show you that you created 2 solids.
you can repeat the operation for n solids and then switch to derivation with the command creates part.
It may sound sniffy, but once you take your hand, it's quick, and convenient in the case of parts that have to vary dimensionally compared to other... .

As for solidworks, the multibody is there, and it is used with advantage instead of the adactivity. . .

thank you 1000, tonight I try and then I let you know!!!:smile:

You made two equal arguments. . .
