How draw swirl surface in 3d in autocad 2014??

[abdullah_iiuc]

I am trying to draw a swirl surface for a pencil battery>> it would more or less like this>> Could anyone show me the way.

Use Helix with z=0

Extrude or sweep surface body

Thicken to solid

Did you figure out a solution to your problem?

If not, can you attach your dwg attempt here?

[abdullah_iiuc]

I got your ans and tried to work that way.but there will be 8 layer here. measurment will be like this>>

1st layer=22um(micro metre)

2nd layer=89um

3rd=26um

4th=89um

5th=22um

6th=100um

7th=14um

8th=100um

and these 8 layer will swirl gradually and the radius will be 9.5mm. hight will be 85mm.

should i do it with scaling or how??

layers will be like this>>>

Did you figure this out?

You still haven't attached your dwg attempt to solve the problem?

ok brother, here is my dwg file. I was able to draw only one laye, but i need another specific layers also>>

[JDMather]

Why can't you model the others?

[abdullah_iiuc]

I can not put the another one within fixed distance (i.e 22um)>>
my question is as i can't use offset here, how can i put one smaller helex within another at a fixed distance??I already provide the distances in my previous comment. Could you help me with drawing another layer at a fixed distance??

[JDMather]

I would start by creating reference circles with the beginning radius of each spiral.

From there - it should be easy.

Could you please elaborate the process or create dwg file with one/two layer??>>e.g tools name and reference etc

[abdullah_iiuc]

Could you please elaborate the process more?? e.x how to create a reference circles with the beginning radius, tools name etc
