Designing a Clock Face with LibreCAD - Part 1

Date: 18/07/2012

In this video I use LibreCAD to create an outer ring with the second tic marks for a clock face.  The final goal is to create a dxf file that can be converted through some Computer Aided Machining (CAM) software to drive a Computer Numerical Controlled (CNC) engraver to engrave the clock face.   
I do not fully know the CAM software but created this file using a lot of "best guesses" based on experience with some machines that probably work similar.  (Old pen plotters).  I did not want to use the hatch function, because I did not know how CAM would translate that so I drew individual lines for the darker tick mark.
Mostly, in these tutorials and other similar educational things, I am showing you "How I would do it" and not creating recipes.for you to follow step-by-step.  The goal is to teach how to think through problems, not what to think.
Since the CNC engraver does not have actual pens to draw with, I am not sure how it will handle various line widths so I used the default line width in this drawing.  I am sure I will get feedback from the gentleman that has the engraver and I will add a comment or update these notes once I find out how it really works.  (Learning in process for all of us.)
