The latest versions of these plugins are available via the SketchUCation Plugin Store, via the Extension Warehouse or at http://www.drawmetal.com/download.

These versions are mostly about bug fixes. It is recommended that you update to these latest versions especially CurveMaker.

One new feature in CurveMaker: When editing a parameter in the "Measurements" box, type a tilde (~) at the end of a value to keep Curve Maker from automatically advancing to the next parameter. This makes it easy to repeatedly edit the same parameter value.

The plugins are SketchUp 2016 compatible.

The latest version of this plugin is available via the SketchUCation Plugin Store, via the Extension Warehouse or at http://www.drawmetal.com/download.

A parameter was added to superellipses to provide the option to draw or not draw a face. The default is to draw the face along with the curve.

If during a session, the parameter is changed to specify no face, that will be the new default for subsequent superellipses drawn in the session.

CurveMaker now draws and edits superellipses. See https://youtu.be/WwAQMDvTRso

Curves such as squircles, rectellipses, circles, squares, rectangles, ellipses, diamonds and squashed diamonds can all be drawn and later edited with this one tool.

You can draw and edit from the center of the figure out or from outer corner to outer corner by toggling the Alt key (Option on Mac). The tool will also draw and edit a portion of a curve (e.g. a semisquircle) based on the values specified for From Turn and To Turn.

Enter an exponent to get the desired shape. For example, an exponent of 0 creates squares and rectangles. An exponent of 0.5 creates squircles and rectellipses. A value of 0.8 generates the superellipses used by Piet Hein. A value of 1 creates circles and ellipses. A value of 2 creates diamonds, etc., etc.

Enter desired exact dimensions or enter dimensions such as 5, x or x, 2 to instruct the tool to compute the value for x such that the ratio between x and the given dimension is proportional to the golden ratio.

Taper Maker was changed comply with Trimble requirements for the Extension Warehouse. That means Undo and Redo work in a meaningful way. The name you give to a taper group appears next to Undo (Redo) in the edit menu.

Also, the mechanism used to draw Boundary Tapers was rewritten. It is smarter, but slower.

The latest version of the Curve Maker plugin is available via the SketchUcation PluginStore http://sketchucation.com/pluginstore?pln=dm_curve_maker_plugin or from http://www.drawmetal.com
or from the Extensions Warehouse.

Just bug fixes...

• Clockwise? parameter was not functioning when some spirals were drawn.
• Construction point drawn at the center (focus) of a curve was erased when parameter values were edited.

The latest version of the Curve Maker plugin is available via the SketchUcation Plugin Store, from the Extension Warehouse or from http://www.drawmetal.com/download

The changes include:

• Undo and Redo work (how they should have all along... but didn't).
• The edit function is accessed from one higher level context menu. No more having to edit the group before editing the curve.
• Display Curve Data is now also available on the context menu.
• When drawing or editing a curve, you can use the arrow keys to toggle horizontal and vertical directional inference locks and use the shift key to toggle a diagonal directional inference.
• Lots of structural changes to meet Extension Warehouse requirements.
• Various bug fixes.

More detail on the changes can be found in the release notes in the Plugin Store.

The Curve Maker, Taper Maker and Stock Maker have all been updated to version 1.4

The plugins are now compatible with SU 2014 and backward compatible with SU 2013 and SU 8.

Most of the changes are bug fixes. The only thing "new" is that they are now distributed and installed independently of each other. So, for example, if you only use Curve Maker, then you need only download and install that one plugin.

If you have installed versions 1.3.6 or earlier of the plugins, you need to DELETE THE FOLLOWING FILES from SketchUp's plugin folder prior to installing the latest version:

ctsMaker (a folder - delete the folder including all of its contents)
curve_maker.rb
taper_maker.rb
stock_maker.rb

Thanks to Rich O'Brien's efforts, they are now available through the SketchUCation Plugin Store.

They are also available at: http://www.drawmetal.com/download

Sorry to be slow in responding, but I cannot replicate this problem. SU's Install Extension option works as expected on my Mac which is running the latest version of Mountain Lion.

Curve Maker now draws the Ionic Volute using the formula proposed by Andrey and Galli (see: http://www.springerlink.com/content/r61qh2354m56qt31/ ).

Optionally, you can draw it with or without an "eye".

You can download the updated plugin from here: http://www.drawmetal.com/download

A demonstration video is available: http://www.youtube.com/watch?v=mES14SnIAP8

For those interested in drawing an Ionic Capital, using Curve Maker and Taper Maker together may be useful as shown in this video: http://www.youtube.com/watch?v=oxXdXy9Gdes

Edit 2012-07-04:
This version is recommended for all users of Curve Maker because it also includes a bug fix. In some circumstances, the plugin would incorrectly determine the drawing plane and draw the mirror image of what should have been drawn. And curves should redraw a little bit faster following any edit made using the Measurements box.

Two new taper (extrusion) cross sections were added to TaperMaker: right trapezoid and quadrilateral.

To create tapers using these cross sections, you must select two paths (rather than just one). The base of the cross section will follow between the selected paths, and the width of the base will vary with the distance between the paths.

Here is an example of some tapered right trapezoids:

This version adds a new feature to Curve Maker and fixes bugs in Taper Maker and Stock Maker. It is recommended that all users upgrade to this version.

CurveMaker has a new feature related to drawing 3d spirals. The Height parameter for an Archimedes, Bernoulli, Fermat, Golden, Hyperbolic or Lituus spiral can be specified as a total height (by appending an 's' to the height parameter value e.g. 10"s). In that case, the spiral is drawn with a constant slope so as to achieve the specified total height along the arc length of the spiral. Note that a length unit is mandatory in the specified height value. Otherwise, something like 10s will be interpreted as a value for the Sides parameter.
