#DesignScript LM – Chapter 13 Translation – Curves: Interpreted And Control Points -Part I

Hi Everyone:

This translation is from the thirteenth chapter of the DesignScript Language Manual and can be found at DSLM  (pages 40-43) and is entitled; Curves_Interpreted And Control Points. There also is a companion video tutorial on – Curves: Splines, BSplineCurves, Interpolation  (#10), which can be found in the DS website’s tutorials.

The initial manual translation was made on the Autodesk DesignScript Community Forum and DesignScript.org. Now it can be found at can be found at Chapter 13, Curves: Interpreted (part 1)  (Note that it can be not longer be found on the Autodesk Labs Website, as linked.)

Reiterating the intial post on this chapter, DesignScript generates curves in two fundamental ways, one is interpreted and the other is through control points.  This chapter is broken down into three sections, the first part is on interpreted curves.

Open the DS Editor and create a new file, lets copy and paste the first page of code from Chapter 13 (pages40) into the Editor.  Run it, and observe that their aren’t any errors generated, as illustrated and highlighted below.

The same can be pasted into a blank canvas of DesignScript Studio.

Edited out the commenting out so the script will be activated, but first make sure that the imported statements are commented out.

As it is developed on the DS Studio canvas the nodes take the place of the script.  Below is what the DS Studio canvas looked like in the initial translation.

The first part shows an interpreted curve via a collection. The next graph node and graphic is a generated curve through input points creating both open and close circles. A more detailed and defined translation was done and involved naming the variables to identify and reference into them to their corresponding nodes.

Then with the naming and identifying complete,  the “Node to Code” operation can take place.

A little editing is desired as highlighted above.

Note that colors were added in this translation, to highlight the geometry in the Graphic view window.

Reiterating, this was done on the stand-alone version of DesignScript, rather than as a plugin for AutoCAD. The files are available for downloading from the Drop-Box links below.

The second part of Chapter 13 will be in the next post.

Thanks for looking.
