This is not for school and must be filled and converted to stl

Hi and Welcome to AutoDesk Forum,

open your CAD file then you can use STLOUT command.

Did you have a question?

I can't get STLOUT, THCIKEN, or SURFSCULPT to work.

Can someone help me? Post a video or just get it done, I can't get it to work, when it says select I use the lasso and it does not select so none of the three commands work for me.

Would you like to know why?

Ah, there's a question...

Those commands will not work because your file does not contain any solids.

Hi,

your drawing must be 3D solid drawing NOT 3D lines.your drawing must prepared by 3D commands.since AutoCAd asks for solids and meshes as you see.

Command: STLOUT
Select solids or watertight meshes: Specify opposite corner: 32 found
32 were filtered out

Select solids or watertight meshes: *Cancel*

Good Luck...

stlout will not work, as your drawing is just 3d lines.

I was going to make the solids for you for fun, but your lines do not make sense, knowing its some kind of mold.

I'd be happy to help if you reply on how we can clean up the crossing 3d lines.

I'll even slice for you in repetier host and send a screenshot of it.

How can I get it done?

As mentioned above, your collection of lines is quite confusing. You will need to somehow communicate your design intent.

he lines should be in the right place, it's a mold star.

Re: Convert to STL

I kind of get the shape, but your lines do not form "faces". Its like you connected 3d dots in space, and did not trim things out so I get left wondering what to do.

Try just tracing the edges of faces on a screenshot. You will see they do not resolve to a real physical void in the block.

Would someone do a video for this one to show me how to do this star(mold the 9 side star), and then I can the advanced ones on my own?

z1=2

z2=1+x

z3=1-x

z4=sqrt2+1-[sqrt2+1]x

z5=sqrt2+1+[sqrt2+1]x

And then do the same equations and let x(z1-5)=y.

I want the mold for this 9 sided star and there are all the equations, preferably in the positive xyz axis so I can get it to STL.

So really I'm looking for a video and file made for this mold of a half 9 sided star so I can print two and fill mold with plastic.

Thanks, kudos waiting

ok, solid modeling is fun. Those equations are not fun.

Seriously, that may be the most difficult way to communicate a solid shape I could think of, sorry its your class assignment.

I can do the solid model easily if I understand the shape.

Looking at your lines, you have not thought this through.

Trim out items that cross through the void in the mold.

I tried, but the linework does not resolve to a void. There are "floating faces" when I try.

Take another whack at it, just draw it on paper if you want. It must make sense though.

To me it's simple, but I'm crazy at the math side.

Re: Convert to STL

JamesMaeding — Fri, 30 Sep 2016 20:07:47 GMT

sure, we can take that star and "extrude" it so the final part is like a piece of cake we cut out a star from, but your dwg showed some fancy 3d connection going on.

Is it really just a star, like you cut it with vertical sides? That would be too easy 🙂

All you would have to do is draw themzx and zy and then connect the points. Every equation is needed and that's as simple as it gets.

Re: Convert to STL

JamesMaeding — Fri, 30 Sep 2016 20:30:07 GMT

if you know the shape, draw it isometric as best you can.

You did a 2d sketch, but then are saying the top and bottom of the start are not "flat".

You need to say what connects to what in 3d.

BTW, how are other classmates doing this?

Others watching might say other progs are easier, but I have found acad is great for 3d modeling.

The trick is you learn to control the UCS (current working plane) so you can use all your 2d commands in 3d, like rotate.

You draw solids and use them to cut out chunks.

So I would draw a box solid, and then the start in 2d. Extrude the 2d star to get 3d, then place and subtract from the box.

Part of your grade is communication though, so take another shot.

It's very simple to me. Those are the 5 equations and you just connect the point from x axis to y axis. It's simple and I just need a mold. You understand the z1-5 equations in 2d xz and then turn 90 and do them replacing x with y and draw the lines, and then connect the ys to xs and make the mold. There is no better way to explain in terms of math, it's simple, those are the eqiations and just must be connected 3d and make the mold for half the star so I can print off two and make the 9 sided star molds.

PS I do not have classmates doing this, as it's for work.

There is nothing more to it.

Thanks, and pre-kudos
