Derived part visabilty

[Anonymous]

I have a derived part which is based in an assembly. I now wish to turn
the visibility off of the assembly and be left with a view of the part.
Is there any way of doing this?

Thanks

Based in an assembly or derived from an assembly?

Maybe I misunderstand the question. If you want to derive a part you can do it from the part file rather than the assembly. If you want to combine a couple of parts in the assembly but not all you can click the +/- options to include or exclude. You also have the option to cut or intersection.

Can you zip and post the files?

i want to combine several parts from an assembly (in this case optics)
and use them to generate a derived part. This will represent the light
path through them. Once the light path is generated I'd like to turn the
visibility off the base assembly (containing the optics) so I just see
the beam.

The original assembly was generated via a STEP translation from our
optics program.

I haves attached a zip file with a small example. In it I'd like to turn
the visibility of the gray discs (representing optics) off, leaving just
the orange surface (the light beam)

Delete Face with Lump option might be what you want.

Another option would be to Derive Compenent the ipt a second time as Body as Work Surfaces that you can then RMB turn off the visibility. I have not experienced any problems with multiple derivations.

How about RMB on the grey discs in the browser and Suppress features? Thanks.

But if you suppress the features any child features will also be suppressed. If Delete Face with Lump is used after the feature is created - no effect on the child.

Paul,

I guess I'm having a hard time understanding just what you are trying to do.
I loaded/opened your "small example". What I see are three "parts" and a 4th
part that seems to have no solid (possibly a work point). Two of the parts
appear to represent mirrors/lenses. The part of interest to you (I assume)
is the sketch/part representing the light path.

Nothing in your example appears to be derived.

Is there a reason that you would not simply set up a view representation
that only showed the light rays?

It is not at all clear to me why a derived part has come into the
discussion.

Further, based on your description it sounded to me like you wanted to
derive from "assembly_A" into "part_B" and then place "part_B" back into
"assembly_A" - which would produce a cyclic situation and is not allowed.

In this case only the three trims are suppressed. This will only work out if these three trims are not important.

If they are I agree Delete Face with Lump sounds easier. Thanks.

You might try a master skeleton sketch technique. Or model the assembly as one monolithic part and then use Derived Components to separate out the individual parts.

As a last resort you could break or suppress derived links if you run into a cyclic dependency problem.

Hi Gary,
Let me start by saying that I have managed to achieve what I desired by
using an earlier tip. I just derived my part into a second file and only
brought in the light beam, leaving the lenses behind (thanks JD).

OK, so the zip file contained a part called "derived from
one_lens_sfs15.ipt" This was created by deriving it from the iam file.
The iam file was created from the product files (which were created from
an IGES translation). The file "product-nameC.ipt" is a representation
of the light rays which I later use to revolve a surface from and create
the beams. The other "product-name?.ipt" files contain the
representation of the optics I want to turn off in the "derived from
one_lens...." file.

I will eventually insert the light beam into a separate assy of the
whole instrument so no cyclic references will be present.

Hi

Thanks for the help. I was not sure what you meant by delete face with
lump option, so I tried the second suggestion. I managed to get the
desired effect by deriving my "derived" file into a second derived part.
This means I could just use the revolved surfaces of the beam and not
link in the solids. Hey presto I just get the beams on show.

Thanks for the help 🙂

Just worked out what Delete Face with Lump is. I agree it is easier and
requires only less file to control. 😉

Paul,
>what you meant by delete face with
lump

Delete Face command and then pick the two grey discs to be deleted. Make sure to click on lump option in the Delete Face dialog. This might avoid file proliferation. Thanks.
