You need to get your head around the relationship between the size of the layout and the eventual circumference.

There are quite a few examples in this thread, http://www.vectric.com/forum/viewtopic.php?f=35&t=6449

And for wrapping a 3D model 360 degrees, look at this particular post, http://www.vectric.com/forum/viewtopic. ... 301#p44301

These examples were wrapped with CNCWrapper, but it is exactly the same thing as we now have inside aspire.

Thanks Greg,

I need to "wrap" my head around witch axis I'm actually wrapping..... This was the source of my confusion.

Thanks for the info and help.

One thing Greolt never mentioned.
If you need a little Circumference calculator like the one in CNCWrapper, go to Andrews site CNCWrapper.com and there is a free one there. Just click on "Freeware"
You can just extract it to the Gadgets folder in Aspire and then the next time you start Aspire, you can select it.

I certainly don't want to sound stupid by where is the "Gadgets" folder in Aspire? I can't find it.

Of course to have the "Gadgets Folder" you have to have the "Upgrade Patch" installed.

I renamed my Aspire folder to Aspire 2.5 and then changed my shortcuts etc.

Paul,

You can machine a 3D surface around a cylinder but you cannot machine all the way round a 3D object.
You can machine a 3D object from 4 sides.

Paul (above) has made a good point.

I did not pick up that Paul (OP) was perhaps referring to a full 3D model.

What has been included in the latest version of Aspire is a method to "Wrap" an XYZ toolpath to a rotary axis via a post processor.

Please don't be confused, this is a long way short of full 4 axis CAM where you can produce a toolpath from a full 3D model. Like for instance a chess piece.

Wrapping is nothing new, we have always been able to do this via a variety of methods, however we now have a post processor included in Aspire.

This is just the first small step toward the day when Vectric will have a proper 4 axis CAM program (are you reading this Brian? :) )

However, even though the wrapping method is quite limiting, there is still a useful range of things we can do with it.

I look forward to seeing, over time, the collective ingenuity of this forum coming to bear on this wrapping method and the work that will be produced.

Just a thought but could it be possible to get close by using some crafty
art work with the modeling tools in aspire and wrapper to create a 3d Model.
