Curve Maker
Draw spirals and other curves interactively, by dimension or by parameter.
Curve Maker

 

Curve Maker draws the following spirals and curves: 

  • Archimedes spiral
  • Bernoulli (logarithmic or equiangular) spiral
  • Catenary
  • Cornu spline 
  • Cotes spiral
  • Euler (clothoide or Cornu) spiral
  • Fermat spiral
  • Golden spiral
  • Helix
  • Hyperbolic cotangent spiral
  • Hyperbolic spiral
  • Hyperbolic tangent spiral
  • Ionic Volute
  • Lituus (shepherd's crook or bishop's crook)
  • Parabola
  • Sine and cosine
  • Superellipse (squircles, rectellipses, circles, squares, rectangles, ellipses, diamonds, squashed diamonds)

Curve Maker provides three ways to draw a curve:

  • interactively, 
  • by specifying the dimensions a curve should have, or 
  • by specifying values for parameters in mathematical equations.  (You do not need to know any mathematical formulas.)

Reviews

I am using Sketchup 2017 (new), is there any documentation on how to use Curve Maker? If so, please provide.

Just the YouTube videos on the Drawmetal channel:

Please provide definitions for the various parameters used to draw helix (and others). Trial and error is getting me nowhere quick.

How do I create a catenary curve? (Like a chain hanging from two points)

Is there any way to get more segments in a parabola? When I draw one it only gives me 20 segments. Thanks.

Parameters (including Sides) are editable via the Measurements Box. After drawing a parabola, hit Return (Enter) to advance from the Dimensions parameter to the Sides parameter. You can edit the number of sides there. Keep hitting return to visit (or revisit) other parameters. Previously drawn curves are also editable.

For some reason, when drawing a parabola and entering the first dimension ending in 8 inches (10'8, 100'8, etc) the plugin will ignore 8 inches and treat the "feet" dimension as inches. For example, 10'8 becomes 10 inches. This happens regardless of entering feet/inches or typing in decimal form.

Sorry you have encountered this problem. The menu option Extensions>Curve Maker>About Curve Maker provides an email address where you can report bugs. Please include a detailed description of what you are doing along with a SketchUp model that exhibits the problem.

Love it mate, helixes were just what I needed!

One problem you might want to look at - it doesn't seem to use inferencing properly in SU2016. Doesn't snap to ends, midpoints etc.

Cheers

how do I draw a parabola?

Hey, may i know how to adjust the Helix Dimension?

thanks!

After drawing the helix (mouse click once to position the center and once to specify the radius), you can edit parameter values in the Measurements box. The parameters you can change are (in order) From Turns, To Turns, Radius, Sides/Turn, Height/Turn and Clockwise?. Hitting Enter repeatedly cycles through the parameters again. Type a tilde (~) at the end of a value (e.g. 10mm~) to keep Curve Maker from automatically advancing to the next parameter. You can also Edit a helix you drew earlier by right clicking on it and selecting Edit 'helix_name' from the context menu.

Nice. thank

hey! wonderful plugin thanks! just out of interest, while installing sketchup warns that the tool requires filesystem access, why is this necessary?

Terry R.'s picture

The menu option Extensions > Curve Maker > Draw a Curve launches a dialog box that contains a field labeled "Options".

You can enter the word "file" in that field. This tells the plugin that you want to input the parameters for the selected curve from a file and/or output the parameters to a file. When this option is active, the plugin brings up a standard system dialog to let you navigate to the desired folder.

With the "file" option, when you have parameter settings you want to save and reuse, you do not have to enter or reenter parameters manually every time.

The plugin also looks for several plugin-specific files (e.g. translations) that it may read.

Thank you so much. Came across your plugin just as I needed it.

A wonderful addition to the program SketchUp thank

Just wanted to thank you Terry R for this great plugin - you're very clever. I have found it is just the job for perfecting the shape of scrolls for templates - previously done with bending wire and hand drawing.

The helix tool does not seem to work. It keeps looping all the parameter entry prompts without actually drawing anything

The menu option Extensions>Curve Maker>About Curve Maker provides an email address where you can report bugs. The helix tool is working properly as far as I can tell. Please send an email with a detailed description of what you are doing.

DANKE!

I can only draw the curves on a certain plane (the blue-red plane). Is it possible to draw the curves on a different plane?

Thank you for your time.

Terry R.'s picture

Curve Maker behaves like standard SketchUp tools. Before using the tool, pick one of the standard views (e.g. "top" = xy plane, "front"= blue-red plane = xz plane, etc.). The tool will draw in the chosen plane. Also, you can draw an arbitrary plane somewhere then click on that plane to draw curves on that arbitrary plane.

How about publishing a proper tutorial in .pdf?
Your video is very vague.
How do I set the distance/space between the arcs to 100mm in Archimedes spiral for instance?

Terry R.'s picture

It's out of date and probably not "proper", but there is a User Guide pdf at the bottom of this page: http://www.drawmetal.com/download
