I don't know if this will help anyone at any point that is new like myself... but it might help me as others may look at the files and suggest a better way to do things if there is one.
So I started replicating a set of templates I use for cabinet doors I make. I did apply toolpaths to this before but since I really haven't delved too deep into that part of the project and tutorials, they don't exist in these versions of the files.. I am just going to verbalize what I did to get to this point. It was really easier than I thought once I found the 'h and v flip' functions were hidden in the Mirror icon..
Set up my material to the finish size and also for a 2sided project.
I drew some vectors out for what will be a cut-off along the top by first drawing lines and then trying to join up an ARC.. After fiddling around a bit I just erased and then drew the vector lines along the right and bottom edge and then made the turn in stopping it at 3". Then I drew a curved line from that end point to the top left corner. Then used the handles to make the arc... the radius isn't of concern so this seems to have worked for me. Then I joined those vectors using the common end point option
With the newly joined vector selected, I used the offset to create the inside vector. This will sometimes be used for a decorative rout that follows the outside edge of the doors. If it's not used.. I just won't assign a toolpath.
Then I flipped to the reverse side and used the excellent guides again to located my hinge cups.
Then I just copied the vectors from the front of the left template, created a new file and pasted, then flipped vertically.. That "flip function" part took me a while to find since I was looking for a more obvious "flip" function. It never occured to me to look for it under the mirror icon. But I see the power that function seems to have combined in there. I like it. I performed a mirror on the hinge cups vectors also and copied the mirror/flipped for pasting into the right door template.
It all seems to have created a very nice set of templates. The only thing I noticed that seems to need fixing is that little 90 degree jump I have coming back in from the outer edge of the door... the lines look like they are drawing in a way that isn't a true 90 degrees... is that just a glitch of the preview? I had the SNAP to Grid function turned on during all the vector drawing. I won't hurt to remake the files and pound this into my memory a little.
