Objects intersecting eachother in assembly. 1

[Mannelito]

Hi.

Im quite new to solid edge, started to learn it two weeks ago. The assignment i currently have is to create a toolbox to show that we have learned to use the different relations. Said and done, allt the joints are sitting well in the assembly, however, when i move the boxes, they are supposed to move a maximum amount of degrees. However, currently they move freely 360 degrees through any objects in the way. How do i prevent this? I have each part, bolts, handles and separate boxes in different .par files. I haven then started to asseble by using the bottom box as ground (.asm) and imported the other par.s into the asm.

Here is a link to the toolbox, it is in one of the pictures.

Greatly Apreciate any help i can get

Mannelito,

you have all parts in that assembly fixed by relations, haven't you?
It would be nice if you could provide a screenshot showing
the edgebar of your assembly.
Any part that still has a degree of freedom can be moved
around as you like, it may cross other parts and so on.
To avoid this a part must not have any degree of freedom,
other than the one demanded by design. An axle should have
the freedom to rotate but not to move in any linear direction
that is.

/Edit

one thing you can do when using the 'Move Part' function (V18)

- on the pop-up near the bottom there is a checkbox
"Stop movement when a collision occurs"
activate it
- then on the left of ribbon bar you'll find a pull-down, set
this to "Detect collisions" (default is "No Analysis")

Now, when moving a part and it bumps into another part the move
will stop.

Setting the pull down to "Physical motion" and the moved part
hits another part it will try to push that part out of it's way
(which can be in the same direction) If that 2nd part can't follow
the move the move will stop.

BTW: the "Move Part" has three options linear, angular and free move
the last used setting will be saved across sessions

There is only one object that is completly defined, the bottom box "Bottenlåda". The other ones are to move in relation to "bottenlåda". I have already tried to check the options when using movement such as the, "detect collisions" etc, but this does not work either.

Hi,

at the moment you have activated 'Rotation', so far OK. When you now
rotate the parts about their pivot point it's rotation is not limited.
That behaviour is normal for any CAD and nothing to worry about.
If you don't like it then you have not only to activate the checkbox
on the 'Move Part' options panel but when leaving with OK you have
to active it by using the pull-down on the ribbon bar and set it
to something other than 'No Analysis'.

All parts so far assembled still show that 'Shaky Icon' to indicate
that there still is at least one degree of freedom. But this may be
misleading in case a part is fully constrained to a part that still
*can* move.

Thank you DonYoung

It was very helpful!

Mannelito,
something forgotten to tell:

to fix the rotation of your boxes you may assign an angular
relation to one of the boxes. Now the rotation is limited
by the current angles' value and the 'Move Part' may
not working on it any longer -- to rotate you have to set
the value to a different angle.
But again this will not prevent the parts to 'slide' through
other parts in it's way when the angle is 'out of bounds' so
to say ;-)
