I think I've got it.  Here's what I did and results (although of course I have no wood and no machine to cut it).  But I got an NGC file (the gcode) and a log file!

1 -- Extensions menu > Gcodetools > Orientation Points
2 -- Extensions menu > Gcodetools > Tools Library > cylinder

3 -- I drew my own offset paths.  Since the tool diameter is 10, and I thought that meant 10 pixels, but it probably means 10mm, I drew offset paths 10 px apart.  But since there was some mention of overlap somewhere, I made the offset paths 9.5 px apart.  It's a bit of a tedious process, and I can see why they tried to automate it with the first 3 Area dialog tabs.

  • Select path
  • Duplicate
  • I'm not sure if this is necessary, but since the Area dialog was making the offsets this way, I made mine this way -- set width to 0.3 px and set color to #999999ff
  • Dynamic Offset - drag approx distance
  • Open XML Editor, locate "inkscape:radius" on the right side and set that number to the offset distance you want, in the section below-right (the only other way I know to set a specific distance, is to set up a grid or guides or something, and use snapping) (I can give you detailed steps for that, if you want to do it that way) (although it might be hard to do if you don't have any perfectly horizontal or vertical paths)
  • Object to Path
  • Repeat #2 through #6 until you have all the offset lines you need
  • Make sure they all got converted to paths, then select all > Path menu > Combine

Here's what it looks like at this point:

4 -- Extensions menu > Gcodetools > Path to Gcode

Path to Gcode tab
 -- Biarc Interpolation Tolerance - I left it as it was, which is 1.00000
 -- Maximum Splitting Depth - don't know for sure what this is, but based on vague understanding, I changed from  4 to 2
 -- Cutting Order - Subpath by Subpath  (if I didn't Combine the outset paths above, I think I would choose Path by Path -- no clue what "Pass by Pass" means)
 -- Depth Function - d

Options tab
 -- Scale along Z axis - I left it set at 1.00000
 -- Offset along Z axis - I left it set at 0.00000
 -- Select all paths if nothing is selected (since I wasn't sure what to select, I checked this box and let Inkscape select what it needs)
 -- Minimum Arc Radius - I left it at whatever it was, which was either 0.05000 or -0.05000 (sorry I don't remember)
 -- Comment Gcode - I left it blank
 -- Get additional comments - I left it unchecked

Preferences tab
 -- File - I entered a name for the file, with .ngc on the end
 -- Directory - I entered the folder where I wanted the gcode file to be saved
 -- Z safe height - I left it as it was 5.00000
 -- Units - mm
 -- Post-processor - I left it at None
 -- Additional post processing - I left it blank
 -- Generate log file - checked
 -- Path to log file - I entered the path where I wanted to save the log file

I'm not sure what any of those colors or arrows actually mean.  But if you notice those places where there are a few arrows on one spot.  It's because there are more than one node there.  After using the Path Offsets, you have to do a good deal of cleanup, because it does sometimes put anything between 2, and something like 20 nodes on one spot, or it creates some kind of weird extra subpaths, sometimes. 

Clearly I didn't get everything cleaned up.  So be sure it's all cleaned up and there aren't any random extra subpaths here and there. And for this drawing, make sure all the nodes are smooth, except for those areas that form a v-shape.

In some places  some of the arrows are actually pointing towards each other.  I think it means that there's a tiny loop in the place where a lot of nodes are on top of each other, but I'm not sure.  Or maybe it's because of being corner nodes where they should be smooth.  Or maybe both.  Or maybe the path somehow got broken there??

And here's the NGC file.  I'm not sure if I can upload the log file, since it has no extension.  I guess I could just make it a text file though.

Ok, so you can see that I made it so that the design (very inspirational blob shape, lol) would be proud, and the wood is cut away around it, because that's at least part of what you're doing, although I'm not sure if all of your project is that way.

I don't know if this would work on your machine.  But I've heard of people who were able to switch out the wood cutting blade for a pen or pencil, and run their file so that it draws on paper for the first test.  So you could use my file for that as a test. 

Although, maybe not, since I used pixels instead of mm.  That probably will throw everying off....  Although on the other hand, it's just a blob anyway.  Maybe measurement isn't all that important for a first try?
I might have just had a brilliant idea  :f5:  Well I didn't have it all by myself.  I searched that topic for "area", and found this reply:  http://www.cnc-club.ru/forum/viewtopic.php?f=33&t=35&p=11543&hilit=area#p11543.  It's from 2011, so it probably pertains to an earlier version of the gcode tools, or maybe even a development version.  But there, he's explaining how to make the offset lines (which I assume are the cutting lines).

So I had a thought.  What if we created our own offset lines?  Then it doesn't matter where we put the "Area Radius" or what is "Area Width" or everything in Step 6.  I think the whole reason for Step 6 is to create those offset lines.

Oh, yeah, yeah!  I went back to the list, where the calculating the area is step....well it's also step 6, but it's a different tutorial.  So after that step 6, step 7 is to open takes you through ungrouping the offset paths and getting them ready.

And then after that, step 10 is to open Gcodetools > Path to Gcode.  When I opened it, I noticed that the 3 tabs in that dialog are absolutely identical to the last 3 tabs of the Area dialog.  So I think the first 3 tabs of the Area dialog are for making those offset paths, and the last 3 tabs, which are the same as Path to Gcode, are for creating and outputting the gcode.

So what I'm thinking is to forget about the Area extension dialog completely.  Make your own offset paths, and after they are ready, go to Path to Gcode dialog and enter whatever you need there, and it will create the gcode.

I'm going to work on an example of my own, then I'll show you what I did.  I'm not sure if I will be able to produce gcode, only because I don't know what settings you have on your machines, which the Path to Gcode dialog needs.  But I might guess, since it's just for practice.  I'll post again shortly  :)
Oh yeah, I was aware of the Measure extension, which can find the area.  But it seems like you'd have to use the Gcode extension, to get the cutting lines.  Because the Measure extension will just give the area -- no cutting lines.

Actually, now that I look more closely at that thread in the cnc-club forum, the last several questions posted there have not been answered.  The last 11 questions have not been answered.  It doesn't look like they pay any attention to it anymore.  The last time a question was answered, was over a year ago.  I might try to PM someone, if it's allowed (I'm not sure, and I don't have IE open at the moment).

I think I'll take another look at your project later today.  Maybe do some more trial and error.  Just using some random numbers, I was able to get reasonable looking cutting lines, the other day.  Not precise for your design, but just for a simple star.  But if I can figure out which values go in which field, then we can plug in the values for your design.

Do you have some kind of gadget to make the embossing?  The embossed part is not an effect, like using an Inkscape filter, is it?

I use a manual embosser from sizzix, Texture Boutique I got at Michaels.  You have to buy the embossing packages, lots of designs to choose from.  See here for a description and photo.... 

If you have more questions, just ask.

I don't have time to actually make a card, but I think I'll try drawing one later today.  I'll post when finished.

What a nice idea!  Birthdays are always sneaking up on me. 
I found this tutorial, Calculate a surface area with Inkscape
I'm trying it to see if I can get anywhere.

""In the following exemple, it is not a string instrument, but a Cajòn (percussion box), which is supposed to have, according to the plan, a circular sound-hole with a 12 cm diameter.
In my case, I didn't want to have a circular sound-hole, but something more funny, and I went for a footprint shape.
Obviously, the total surface of the holes composing the footprints must be equivalent to a 12cm disk.
1.Calculate the surface that we need to respect  : 12 cm diameter = 113.1 cm². ""

Area Width by the 2 definitions below is a measurement of complete area (LxW) and across the surface at it's widest point, in my case it should be 9 inches, but this also does not work.

a region or part of a town, a country, or the world.
"rural areas of New Jersey"
synonyms:   district, region, zone, sector, quarter, precinct; More
The extent or measurement of a surface or piece of land.
"the area of a triangle"
synonyms:   expanse, extent, size, scope, compass; More

The measurement or extent of something from side to side.
"the yard was about seven feet in width"
synonyms:   breadth, broadness, wideness, thickness, span, diameter, girth
"the width of the river"
a piece of something at its full extent from side to side.
"a single width of hardboard"
the sideways extent of a swimming pool as a measure of the distance swum.

screen shots coming.
Thanks Brynn.  :xf1:
I will keep an eye on this.

The difference in browsers made a real difference in what was stated.

]I did this a couple of years ago and now that I'm older, as they are, I don't remember how old they are and those 13,16,18,21 birthdays are so special so I am am updating to include year born....well maybe not the "big kids" but the grandkids.   :-) 
I thought I'd share this again if anyone else will find it useful. I did P2C and laminated it (magnet on back) for each of our 4 children. Now that I have adult, or almost adult, grandchildren they will get one too.

Posted this on my blog this morning, nothing fancy but really easy to DIY.  I cannot post a file for you since I do not remember where I got the tulip...but there are a bunch of tulip svg to chose from.

See a description on my blog

I'd love to see your interpretations...make it a challenge????   :wink1:
