Elaborate on this command?

 

AutoCAD 2007 or later.

For elaboration see the tutorials in my signature.

Ok, you guys are getting into areas of CAD that I honestly don't know enough about. I've been using CAD since '97 but have never had the need to twist anything until I got into designing ships (recently). What is a lisp command and what does it do? Also, another complex solid question: Does 2007 have the option of REVOLVING an object, but on an elliptical path that stretches the pline to match as it is revolved? If so, can it be done in 2005?

 

Here's what I'm trying to draw (look at the panels on the rams on eahc side of the fuselage, as well as the power systems located adjacent to the rams on top of each j-wing (has five panels that have a slight twist):

ST, re your lisp question take a look here. http://www.cadtutor.net/faq/questions/28/How+do+I+use+an+AutoLISP+routine%3F

As for the revolving around eliptcal path .. maybe you could give a screen shot of what your trying to do..

 

Also my first thought was maybe extrude..along an eliptical path..

 

Dude your in for a world of hurt....thats a pretty complex object....how long have you got.

Yeah, I tried that. It ends up extruding the profile I created and, if the object is outside the path, it leaves ahole in the center; and if the object is on the inside of the path, the profile intersects itself. I'll try to post some shots.

Profile of object to be revolved and the elliptical path:

 

 

 

 

 

 

 

 

 

 

Left: Inside Path

Right: Outside path

 

 

 

 

 

 

 

 

 

Extruded objects

Left: Intersects itself

Right: Leaves a hole

 

 

 

 

 

 

What I want to do is actually REVOLVE the object but have the profile stretched or contracted from the axis to the elliptical path as it is being revolved.

Appears to me that you really need to upgrade to at least 2007, so you will have the LOFT and Sweep options available.

[SilverTiger]

I guess I have to. But in the meantime I guess I'll try to learn that lisp thing for the surface meshes.

My goodness...that M2S autolisp just became my best friend!!

Finally!!!! Thx guys for all your help! You made it happen.
