2d view question

Post by Fivetide »

Hi I want to put a single vector along the Y axis and use the same vector to control the varying depth of Z but I cant work out how to flip the 2d drawing so I can do this. Could anyone help ?

Try using the Fluting Toolpath....

Thanks highpockets, I looked at the fluting and again couldn't work out how to bring a shaped vector I have drawn in Auto cad to control the Z height along the Y cut

Sorry I didn't completely understand what you are trying to do. I'm still not real clear, can you post a picture or two?

Hi yes I need to explain it a bit better sorry : imaging you have a 3d carving of a face on a board, I just want to carve one of the vectors along the Y or X + the 3d heights on the Z . In other words I want to draw a single vector of various heights and curves etc (the Z), and project it along the X or Y. A single vector of the 3d model.

Nope, still confused. :oops: :oops: :oops:

I'm not understanding the 3D model and what it has to do with a single vector.

A picture/sketch, something would help. Sorry to be so dense.

Don't worry John your not the only one :lol: :lol: I am not sure if the OP just wants to project a vector cut onto a 3D model or if they want to try & generate a vector from the 3D surface :oops: :oops:

I can’t decipher the description either, unfortunately.

Yep...a sketch may help.

I think that it is one of two possibilities that you are after.
If you already have the 3D model you can do it as follows:
Draw a straight line vector in the direction and position on the model as required.
Make sure that the model is visible in the 3D view.
Use profile on tool path with a depth of cut of 0.00 and make sure that project onto 3D model is checked.
That will give you a toolpath that follows the model in the Z direction

The other possibility is:
Make sure the model is visible
Go into the measurement tool and select model cross section.
Click a start point and an end point and the software will compute a cross section vector for that point.
That will give you a vector that follows the shape of the model at the specified point.

I hope that helps

Maybe it would be better to explain why I want to do what I’m asking. I have made my own wood lathe spindle copy attachment. (see picture please) It only uses the Z + X axis, its not a rotary machine as I’m using the existing DC motor to turn the blanks. So - to cut out a spindle leg I only need the shape of the leg along the X axis and its corresponding height using the Z axis. If I where to draw the spindle leg in vectric I would use a single vector as the shape and then wrap it around the cylinder. So I’m attempting to trick the machine into thinking it’s a flat block of wood that I’m essentially trying to cut a single straight groove along the top (X) out. So in the below attachment it would be just that single shaped vector along (X) and down (Z) into the wood blank.
I hope this explains it as I have no idea how to explain it anymore lol

Now that we can see what you see...

Hey John: How about a moulding toolpath that only generates one pass?

Steven, I think you're right. But then I've been confused all along on this one :lol: :lol: :lol:

The "Swept Profile" a.k.a. moulding toolpath gives me a headache every time I use it.

It won't work in this case.

The only thing I can think of is model the spindle as a narrow 3D component and do a 3D finishg toolpath on it such that it only generates one line.

See attached VCarve v9.512 file.
