Jagged edged geometric entities like circles & rectangles

I wish to use Geogebra for creating "geometric dimensioning and tolerancing" (standard for engineering drawings) calculators and educational demos. In engineering it is well understood that there is no such thing as a perfect shape. When we zoom in on what appears to be a perfectly flat edge, flat surface, or flawless curve or a sphere, or a cylinder we find that they are all actually very jagged. By creating geometric entities having imperfect or jagged edges we can generate some very useful visual applications for demonstrating how to apply the latest gd&t standard (ASME Y14.5M-2009).


Here is a link to a short video on a very simplified aspect of GD&T.

What do you need adding to GeoGebra?


(you can make the (dynamic) diagrams from the video quite easily already I think)

Yes that looks correct. How did you do that?

I need a tool for easily creating imperfect geometric entities. For example a circle or straight line with jagged edges.

the image are two circles, equal radius equal center; the second circle is dashed-dotted and more thick

you can do a tool for your creation

saludos
