cresting lines out side of your work area

[cusoak]

I want to make boxes with sides out of 1 piece of plywood.
So I need for the 90 degree v bit to start out side of the box.
So I have a piece of plywood 10x10.
I need the sides to be 1" high.
For this to work I need 4 lines that are 12" long and 1" out side of the piece of plywood.
Setting the profile cut to.249 cutting depth This will create 4- 45 degree groves.
You cut the 4 corner off and the sides will fold up creating a 1 piece box with all the corners having 45 degree miters.
So my question is this can the poly line function be used to create lines that would extend past the boundary box using the z and y settings .
So how would I go about setting up the file.

The material outline is just their to help/remind you where your cuts are relative to the material. You can draw lines outside the box and make toolpaths that cut even if there is no material showing.

You can draw & toolpath outside of you material block set up & all will work fine, the only problem you will have is with the preview which won't show anything outside of the work area
Just a little bit of extra info, mitre fold boxes are normally cut with a 91 degree bit not a 90 deg bit

I've done some open ended boxes where the miter is visible, so you have to use a 90° bit. As long as the bit is cutting clean, a 90° bit will work just as well as a 91°. Sometimes better.
But yes, 91° is what's most often used.

Ok next question.
In the Create line /polyline there boxes where you can enter x y values to place a line where you want it. How do I figure out what sort of a number would go in to them to get a start point and a end point that would be exactly where I want it in relationship to my work area, say 1.5" in from the side and 12" long.

I usually start lines at an existing snap point (0,0 for example), extend them in the direction I want them, and before clicking the end point I type (on the keyboard) the length ("12 enter" in your case).
Then while the line is highlighted I use the MOVE tool to move them up and/or over to where I want them to be.

where are you entering the 12"

It somewhat depends on where the origin is, and the size of the material.

Say your origin is at the bottom left, and you want a vertical line. For X you enter 1.5. You didn't say where you want to start,, but if you are starting at the bottom edge, than Y=0. Click Add to start.

Now, the easy way to draw a 12" line, is to move the mouse straight in the direction you want, until the display says A90. Then just type 12 and hit Enter, and you'll have a 12" line. (You are not entering this in any box or window).
The old method would be to enter 1.5 and 12 and click Add.

You really should watch the video on the new drawing tools.

where are you entering the 12"

Just type it. Have a look on the Help menu under Keyboard Shortcuts and then scroll down to the Quick Keys section.

not to sound too stupid where do I find the new drawing tool video.
I found one from 2008.

The latest videos are always on the support site - http://support.vectric.com - problem with YouTube is that you have no idea what version of software the video was made with.

You can also access the tutorial and what's new etc from the Help menu in VCarve.

The video you need in this instance is http://support.vectric.com/tutorials/V9 ... ideo_id=99

As well as the support site Adrian linked to you can also access all the training tutorials, tips & tricks etc through your Portal Accpont

I am making the fold up boxes using a 90 degree vbit where I set it to a certain depth as to not cut through the wood all the way. I see in the job set up page that there is a stepover on .01
Is that ok to leave there or should using a vbit to plunge down to a set depth should there even be a stepover value at all.
Jeff

[Adrian]

Not sure what you mean by stepover on the job setup page. Stepover settings are to do with the tool itself and are in the tool database or associated forms in the toolpath setups.

The stepover is a horizontal movement amount when a bit has to move sideways to complete a toolpath such as a pocket or a vcarve that is wider than the bit. It wouldn't apply in the case you mention as the tool is only moving in one horizontal plane.

Thanks Adrian for your help that is what I thought.
