Need skeleton modeling tips

I am new at skeleton modeling and any tips would be helpful.

How do keep your skeleton from getting so big, that you its hard to read any
numbers, keep the lines apart (different colours would be nice)and getting
slow.

Seans site "sdotson.com" has a good tutorial I believe that is where I got it from.

You aren't trying to do it all in one sketch are you? Break it up into multiple sketches
that you can turn on and off.

Yes I have everything in one sketch. =(
The reason is and hopefully you can help me out here,
1 The whole sketch has to grow and shrink with each other.
2 I can't measure from one sketch to another with out projecting the line.
3 If I go into the top sketch all the sketches below disappear, and I need
to see them.

like I said I'm new at skeleton modeling, and I'm sure there are answers for
all of my problems.

Master sketches usually require some planning ahead but in the situation you
mentioned about needing lower-level sketch geometry in the top-level sketch,
you can copy/paste the lower-level geometry into the top-level sketch when
necessary.

Bit difficult to imagine exactly what you are doing without guessing, can
you post the file?
To minimise the amount of information in a sketch try using more
construction geometry and constraints?
Make your sketch1 your base sketch which will include general overall
geometry and dims.
Then for additional features in sketch2 project only basic controlling
geometry and or use equations (link dimensions by selecting them from your
sk1 whilst in sk2 :- edit dim-select drop down arrow-measure-select ref dim
and add equation as necessary)
Use offset planes from origin geometry.
Make heavy use of origins for constraining sketches etc.
Rename sketches planes axis points with a meaningful name.
Doing this means you can link any thing from your base sketch and control
the whole model as desired / required and studying the browser is easier
than opening the sketch to see its contents.
It would be nice to colour sketches for better clarity but I normally make
all or as required sketches visible then in an iso view you can study
construction of model as well AS editing any sketch dimensions.

With Master sketching I do a fair amount of projecting lines (actually I generally try to
project line endpoints so as to keep the clutter down.) to new sketches.

Your item 3 is no different than what you would run into editing a top feature in a part.
Approach your Master sketch the same way you would build a single part. The first few
sketches should be the base for your part that everything uses to grow and shrink from.

I sent file to customer files.
Thanks for your tips and Larry and Kents as well.
They would mean nothing to me if I hadn't tried it before.
Its going to be nice once I get on to this skeleton modeling.

Don't have a lot of time to look at it right now, but the first thing I see is .... why
are you using constraints in the assembly?

You might try using the insert and fix macro on my site.
http://www.mymcad.com/KWiK/mcad.htm

It also looks like you could get rid of some of your dims if you used more = constraints
(if you can get them to work that is )

It really doesn't look that messy to me. Here is a couple of shots of one of mine ( Of
course I don't really work on it with all these sketches turned on)

Save them and check. I see 85 kb and 52 kb. You can't trust what newsreaders report 8^)

Lester,

Just want to mention that your grounded part "Cover End Angle tube" is
slightly tilted by 0,81 deg (measured from XY Plane). Is this what you want?
And look at the origin planes they are not near your grounded part. Try to
keep them logical (f.e. in the centre of your assy) according to your
assembly.

Check out Kents (like he mentioned) "insert and fix" program. This works
great for skeleton modeling.

Greetings,
Christian

Thanks for the tips

I definitely don't want it on an angle.

I will check into Kent's program as you said.

This skeleton modeling has been done backwards. I whipped up this 300 plus
part piece of equipment for the customer to see. Now that he wants it, I
have to change all the sizes. That is when I decided no matter what, I have
to learn skeleton modeling.

Glad I could help.

Skeleton is the way to go in my opinion. I'm glad I learned it from this
newsgroup.

Christian.

Wow
Now that looks confusing.

Am I right on this?
All your parts are derived from this skeleton?
Doesn't that make huge file sizes.

Yes that is all the manufactured parts in a rack mount computer chassis.

My basic workflow is to take the major purchased parts that will go into the system, and
copy them to my workgroup dir. I assemble them in space using the origin planes for
reference in the general area I know I will want them.

Then I derive this assembly into a part file which becomes my skeleton file. I can use
the faces and edges of the derived parts to build brackets etc on.

In that file it is rare that I ever have more than 2 or 3 sketches visible at one time.
You start using sketches kind of like what you would use layers. I try to "Name" all my
sketches in the master to help keep things sorted out.

I have had a couple of discussions with the developers about some improvements I would
like to see to help cut down the clutter, and make Master sketch modeling a little easier.
Hopefully a few of them will make it from the wish list status to a released product 8^)
