Hi guys,
sorry if the question looks easy for you, but I've recently starting using Autocad for my 3D printing hobby,
I'm currently looking to remove some material on a cylinder, it's not as easy as I tough, I've been watching video over and over on how to remove material on a cube (not an issue) but with the cylinder I feel it harder...
so far I've done it this way,
design my cylinder in 2D with facing top
then switch to iso - using the push/pull command to render the way I need
then I have redefine my Axis and after this is where I'm stuck
please see bellow - the yellow is the materials that need to be removed
only the yellow material has to be removed,
if you have any idea or a "best pratice" for that - I would love to know, I've been stuck for over 4days on that
thanks,
Quentin.

Did you mean presspull?
Can you attach your *.dwg file here?
Are you familiar with manupulating the UCS?
Because the yellow object(s) do not lie on the surface of the cylinder, you can not PRESSPULL them through the cylinder and also SUBTRACT the new volume in a single operation. Try using PRESSPULL or EXTRUDE to creates a new solid object first, then SUBTRACT it from the cylinder.
that what I've done and it's working 🙂
not sure what UCS mean, but what I can tell you is I'm not really familiar with the origine set, and I believe this is the key for 3d...!
The master of 3D is the master of the UCS (User Coordinate System).
Nexty,
JD is correct - to master 3D in AutoCAD you must be familiarwit and master the UCS. One thing to remember is that AutoCAD will always draw objects on the current X-Y plane.
Another thing to be aware of: When Dynamic UCS is turned on the UCS will change as you select objects. I can't fully describe it, I basically hate it and have it turned off.

...on the other hand, I find DUCS to be a real time saver and seldom turn it off.
JD, just curious, do you much in the way of custom lisp routines?
I ask because much of what I do for modelling is through custom lisp routines and DUCS seemed to get in the way of using them. I could probably rewrite them to work that way but it got me a little befuddled when I first encountered it.
I should give it another go sometime.
Ok,
I'll give a try with DUCS enable and will let you know
I feel after practicing a bit yesterday that I'm getting a bit more comfortable
Actually, if you don't really understand UCS yet, probably best to have DUCS off until you are a master of the UCS.
