Part file size.

[vnet]

Hi, I designed a electric guitar and I did everything in a single part file with many bodies all dumb bodies and not an assembly.
Everything is fine and the file size is about 28MB in size before I put on the strings, especially the three wound bass strings that I used a helix curve and the tube command to create.
Boom, the file size goes to 300MB and the only parametric features in the file are the helix and tube that I kept in order to adjust the parameters for the strings.
Why am I doing all this, mostly for rendering purposes, I could design the strings as a flat tube and use a texture in the rendering but I like the way this looks better and it is more true to the part.
Is there anything I can do to reduce the file size, don't get me wrong I can use what I have, it would just be nice to have a smaller file to render and work with in CAD.
Would an assembly of the parts now that they are all designed be better than a single part file or would it be large as well 160 bodies to make a whole guitar.

Thanks Much, Buddy.

I don't think it's because the 'strings' are features but rather because of their complex shape. Now you could reduce (make it a larger value) the modeling tolerance for those parametric 'strings'. Just edit the feature, change the tolerance and update. Now this is not going to make a BIG difference, but it should help somewhat.

Or you remove the Parameters from the feature.

I use remove parameters from parts all the time for a variety of reasons, it is one of my favorite commands but in this case it did not reduce the file size.
Thanks, Buddy.

The fact that those guitar strings are or are not 'features' will have very little impact on the size of your model. It's the complexity of the helical bodies which make-up each string, that's what is contributing to the large size of the part file. Either replace them with simple 'tubes' or use a larger modeling tolerance when you create those bodies. Note that you can't edit the tolerance of those bodies IF you remove the parameters.

Hi,

Have a look at the single or multiple face setting in tube parameters.
Multiple will be better I think

I will play around with the single setting but the feature would not build with single face, something about overlapping planes.
What you see is multiple.
I still do not think that is going to help with the file size, But thanks.

Buddy.

No, I can see that you didn't use the 'Single Face' option just by looking at the results. No, either replacing the 'coils' with a single 'Tube' or reducing the tolerance is the only hope that you have.
