Creating a complex 3d object/solid

[Reqviem]

Hi,

 

I am kinda stuck with a college project at the moment.

 

I have the 3d model of a ship, but it has no surfaces or solids, just lines.

I want to create some solids based on those lines.

 

It's better if i attach the dwg to the post and explain what i want to do:

- in the file attached there are some lines maked with red and blue

- i want to create a solid/3dobject by extruding/lofting the red lines along the blue lines.

 

In the drawing only a few lines are coloured, for better undestanding.

 

I tried with loft, but it only creates some surfaces. The point is that i need a solid or a 3d object.

Hi,

See the AutoCAD tutorials in my signature.

 

As a college student I think I would want to be learning the next-generation tools like Inventor or Alias to do something like this.

Students can get modern CAD software for free from http://www.autodesk.com/edcommunity

In college we stopped using Autocad in the second year and we moved to dedicated software for our specialty such as Tribon and Aveva.

 

But, now i'm stuck to Autocad for two reasons:

- i can get the volume and mass center of an solid automatically

- it comes free.

I don't see any red or blue lines. Everything seems to be a polyline? 3Dpolyline by any chance?

 

I suppose you could try lofting between adjacent lines that are on the same layer but you better have a halfway decent computer to do it. That's a lot of lines and a good number of lofted surfaces.

[Reqviem]

Yep, all are 3d polyline.

 

Here, i attached the file again:

If you can't see them:

In SW Isometric

- blue ones are the ones paralel to the horizontal plane

- red ones are the ones paralel with the vertical plane

 

Here's a picture

Like I said, you can loft them but I'd work with a small group at a time.

 

By the way, your Profile says LT. You must be working in full AutoCAD at the moment right?

Yes, atm is AutoCad 2007 full version.

 

After i loft, how do i convert them to a solid/3dobject?

[ReMark]

I'd suggest the THICKEN command but I'm not sure it will work given the geometry.

Tried it. Doesn't work.

 

After some thinking, is there any way to trim a cube with a lofted surface? Because that's the main reason i want that surface to be a solid.

[ReMark]

Try the SLICE command. It might work. You want to use the SURFACE option.

Doesn't work.

 

Anyway, i spoke to a buddy and he said i should use AutoCad 2011 so i can use trimsurf to get what i want.

[ReMark]

I believe he meant to say SURFTRIM. 2011 also introduced SURFFILLET and SURFPATCH.

 

I haven't used any of these because I rarely with with surfaces.

[Reqviem]

Yes he just corrected me.

 

If there's any way to do what i want in Autocad 2007 i'm still interested though.

[ReMark]

I would have to play around with it some but unfortunately I have to go out for awhile. When I return and if I have the time I might give it another try. No promises though. Good luck.

You must have skipped my suggestion to do the tutorials in my signature.

I would start thinking about doing them.

Welcome to the forum.

As a student you have the option of downloading a free student license of ANY of the current Autodesk software products.

Why do you choose to use a 6 year old version?
