Need help with sword sheath.

[Anonymous]

Hello. I'm Rob. This is my first 3d model, it was quite an adventure

I made this sword and sheath, but I'm having a hard time fitting the 3d prints together. 

I cut the body of the sheath with the sword, but the tolerances I left seem to not be enough. 

How can I make the inside of the sheath follow the shape of the outside?

couple of approaches-

1-create a smaller version of the sheath and combine/cut it out of the center of the sheath instead of the sword itself

2-or use shell on the sheath

general pointers-

-in solid modeling programs like fusion, it's a good idea to avoid using the move tool to position bodies the way you have here.  The reasons are numerous, but suffice it to say it WILL cause you difficulties down the road.  (I aware this is a standard practice in other types of 3d software, but parametric modeling is a different beast)

-read up on components, and start trying to use them.

-if you are going to use timeline mode, be mindful of the time line, and use it to your advantage.  one example-cut your model up for printing last, but when you want to do edits to the model, move the timeline to before you do the cuts.

Thanks for your reply, i'll try these methods.

I was not aware moving things would cause problems, i made something in skechup once before and i assumed it would be similar.

I have not gotten into components at all, i will read up on it.

Is it beneficial to use direct modelling mode?

DM mode can be advantageous at times, but then again so can time line mode.  It depends a  lot on the nature of the object.  In this case, i would probably use timeline mode.  But if you do use timeline mode, it's important to be mindful of it.  You want to go back and make edits in the timeline, and not be continuously tacking more commands onto the end.  If that's the approach you prefer to  take, then DM mode will be better.

I sometimes use a highbred approach, creating the object in a base feature (which is like DM modeling), but then using timeline mode to do something like cutting the object up for printing.

Hey i was able to cut the sheath the way i wanted it. I copied it and scaled down two of the dimensions. I ended up with too thin a wall in a small spot due to the outside detail cutting through, so next time ill make sure to remove the details. 

Sorry if this was an obvious fix, i was following the "the sword cuts the sheath" way of thinking.

Thank you!
