Updated Geometry Tools

[JuneTheSecond]

I've updated geometry tools stencil.
Geometry tools are the shapes useful to analyse or build very precise geometrical shapes.
This is a stencil of vss file type.
Save this file in your own stencil folder.
Open this stencil file by the side of your drawing.
And drop tools on your drawing.
Each shape has hyperlink to the short video
registered in YouTube to explain how to use.
Each video takes you not more than 1 minute.
You can see the video by pressing Ctrl key and clicking the shape dropped on your drawing.

excellent work as usual....well done

Any thought to a version of arc 2 360 that gives an ellipse vs circle?

Too difficult for me.
But made a simple one
that start from BeginXY passing through a control point end at EndXY.
You can specify axis angle and axes ratio by shape data table.
You can see short video by pressing Ctrl key and clicking the shape.

thx....appreciate the help

I was looking for a more algorithmic way to do it (control handles are great for all the "artists" out there, but for
precision work, something more "predictable" is needed).

But again...thx for the efforts!!!

I figured out how to do a parametric elliptical arc
In hindsight,its embarrassingly obvious....but that is for another day

Basically
   - Set some custom properties
         Major radius
         Minor radius
         Arc length in degrees
   - Move to (for now) is the point at the end of major radius
        In the future, I may define an arbitrary start point now that I got the hang of this
   - In the elliptical arc row, the following
         X = width*0.5+prop.majorradius*cos (arc length)
         Y = height*0.5+ prop.minorradius*sin(arc length)
         A = width*0.5+prop.majorradius*cos(arc length/2)
         B = height* 0.5+prop.minorradisus*sin(arc length/2)
         C = angle   ///so I can rotate this based on the angle cell up by the width cell
         D = prop.majorradius / prop.minorradius.

embarrassingly obvious!!!

Since Arc length = 360 deg makes a straight line, I did add a condition row that would allow one to close the arc or not

Later, I will make it so it can scale with a group.

Hope it helps all

I've added elliptical arc 2.
The shape has hyper link to the short video registered in YouTube.

Geometry tools are useful to analyse and build very precise geometrical shapes.
I've built many precise geometrical shapes using these shapes.

I hope you enjoy them.
