Welcome to the forum!

For the exact angles, it depends on the angle, as to the best way to create it.  So you'll need give us a specific examplle....or else dive into some tutorials, and start learning Inkscape.  For a complete novice, I would suggest Help menu > Tutorials > Basic, Shapes, and Advanced (don't worry, the one titled "Advanced" is really written for newbies, but for some reason was give an unfortunate name).  After that, you can find tutorial listings by skill level, here:  https://forum.inkscapecommunity.com/index.php.  There are some more tutorials in the Quick Start chapter of the manual, which can be found in the Help menu > Inkscape Manual (requires internet connection).  And of course you tube contains countless tutorials.

For the exact size, you should draw the image or object at whatever size is comfortable for your screen size.  Then when it's finished, scale it to the correct size.  Object menu > Transform > Scale

Or in some cases, it might be better to draw it the proper size from the start.  But that's really just a personal preference.  For example, if you  want to use a grid, it would probably be easier to draw it the correct size from the start, by snapping nodes to the grid.  http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Snapping.html

If you have instructions for the decals which tells you to draw a line with this angle and this length, it sounds like they might be expecting you to use a CAD program.  Inkscape is not a CAD program, and doesn't work the same way.  If that's the case, you might try LibreCAD.  I'm pretty sure it's free.

Hi, I'm brand new to Inkscape and would like to use it to create decals and stencils for my radio control cars using my new Cricut One. The shape I'm making first is a curved windscreen banner that needs exact angles and sizes. Can this easily be explained here, or is there a tutorial out there?

Brian. :b1:

Oh, I didn't realize Inkscape had other DXF export extensions.  So I've searched through extensions, and here's nice list you can look at!

I don't know which ones work, or work with which operating system, or which cutter hard or software, or which ones might be broken.  This is just a raw list which you can research.

The last 2 might be different versions of the same thing - I'm not sure.

--EDIT--
I just tried an option (I read it somewhere but, sorry, I can't find the site again). So, I unchecked the "combine lines while import..."  option on the SmartCarve settings,

then, imported the file (the lines of the file are chopped and you get a lot of small paths), right click on the work area and choose "link line", and all the lines are joined to the original paths!!!!

So, this is not the answer to the problem, but still it might help others who have this problem.
--EDIT--

Hello. I looked at the software list, but buying another software for the laser cutter is not an option right now (and I'm not sure the machine is compatible), thanks for the information anyway. LibreCAD is free and I use it, but it does not drive the laser cutter.

there are several DXF output extensions besides the one that ships with Inkscape. There's a chance one of those would work better for you. As I recall, some of the names are "Better Better DXF" and "Big Saw" or something like that.

Thank you cleversomeday, I tried to install the extensions for Better DXF but it did nor work on Ubuntu or Windows, I also tried older versions of Inkscape, but my guess is that these extensions don't work because of new python libraries.

Thanks anyway, I'll keep trying,

Help Using Inkscape / Re: Single vector from Tracing?
« Last post by cleversomeday on April 01, 2018, 12:37:10 PM »
There is a center line trace extension for Inkscape that might work (can't remember which OSs are supported).
https://github.com/fablabnbg/inkscape-centerline-trace.
If that doesn't work, there are a couple of online converters such as Rapid Resizer you can try cleversomeday.com/rrcenterline
Several others are listed here cleversomeday.com/sketching

Based on the fact that the DXF looks good in LibreCAD this does seem to be a problem with your cutter software's import, but I do want to mention that there are several DXF output extensions besides the one that ships with Inkscape. There's a chance one of those would work better for you. As I recall, some of the names are "Better Better DXF" and "Big Saw" or something like that.

Here's the list he gave.  Personally, I don't know anything about them, whether they are free or whatever.

Fusion 360
SheetCamTNG
Alibre Design
LibreCad
MOI3D
V-Carve Pro

Oh, I think LibreCad is probably free.  But I don't know if it will interface with your hardware.  You'll probably have to do a little research for that - owner's manual or something.

Thank you Brynn.

Can you recommend a cutting software? Are there open source options?

thanks again

There was a response to my bug report from someone who is not a developer.  But he tried the DXF file which you provided, which Inkscape produced, in 6 other CAD/CAM programs, and it performed flawlessly.  So perhaps rather than use Cenon to export the DXF, using a better cutting software would be more appopriate?

I don't really know the right answer.  Just sharing the info with you.

Ok, thanks for that info.  Indeed, I think developers need to know about this (if they don't already).

Thanks again  :)
