Creating a 3D mast

[Silent Ace]

Hello,

 

It seems that i cannot find a solution to connecting two circles with different diameter into a solid. I tried loft, but it is a partial solution since it creates a surface. I know there is a solid option. There surely is a way and a simple one but i don't know how. Bellow there is a picture with diameters and length of the mast. Also i included a dwg file. Not much done there.

 

Thanks.

See

for one way of doing it.

I didn't look at the youtube link, but I think what you want to do is Loft and Shell solid

or

Loft and thicken surface

or

Extrude with taper and shell

or

Extrude surface with taper and thicken.

 

So many ways.

 

Revolve angled line as surface and thicken

or

Revolve angled rectangle.

 

If you still can't figure it out - post back and I'll attach sample file with at least 6 different ways.

In my opinion an angled line revolved as surface and thicken is the easiest solution.

Well it seems that loft is working well if you chose path (line connecting the two circles in the center), creating the 3d solid. I tried the thicken command as well works to some extend, but still leaves a hollow part inside which i don't want. Also i tried removing the hollow part with solidedit as a face and deleting it. That didn't worked. As for the sweep command works with scale, however calculations need to be made for the scaling factor. Thank you both for your help, i learned a few new things along the way.

You did want the mast to be hollow didn't you?

[Silent Ace]

It's for a scaled boat model, so it doesn't need to be hollow. If it was a real one, then yes .

I see. Well then my command of choice would have been LOFT as well.

Loft will work for you, watch the command line, pick the MOde option, change to Solid from Surface, continue on. You will have a solid instead of a surface.

Revolve is far easier than Loft.

 

With loft you need to move (or create) circle to elevation.

 

With revolve you simply create 4 lines, dimensioned to your major diameter (or radius), minor diameter and height.

If you use Parametric dimensions - you can easily change.

Create two circles, one at Z=0 and the second at the necessary height then loft. Doesn't sound like that much more work to me.

Draw two circles, move one, loft. Pretty easy.

Are you saying the parametric dimensions will change a 3D object? Can you walk me through that?

+1:thumbsup: Definitely.

Not in AutoCAD.

 

Set DELOBJ=0 and if you decide to change double click on the dimension to change and then Revolve again after change (delete the original solid).

 

I have no clue how you would do that with two circles (in AutoCAD).

[rkent]

With either revolve or loft you just grab the grips and adjust the size by typing in a value to increase the circle by. I misunderstood you concerning the parametric dims.

Loft all the way.

 

For some reason i wanna draw a boat now.

A nice pirate ship or a 12 meter yacht? LoL

[Bobzy20]

Yeah a real pirate ship would be great where as a somalian version would be rubbish.

Wow it seems i made quite a discussion here . I already posted my work and files here http://www.cadtutor.net/forum/showthread.php?81044-Santa-Maria-Model. Thanks for your help.
