With this, we are able to encapsulate the parameters and throw them around as a whole " hash bundle". Len = ops("len") // convert to local scope Wrench_default = Ģ) Secondly define a hash function to get value:Īnd since functions and variables use different name spaces, we can take the advantage and define this function:įunction wrench_default(k) = hash( wrench_ops, k) I encountered this situation quite often and here is how I dealt with it.ġ) First define an array to encapsulate/group similar parameters in a pattern of key-value pairs: I think that would become almost unreadable.Īny hints on a good way to handle this? Or options I should consider? I considered creating an object/module with those dozen parameters, but #OPENSCAD MODELS CODE#This approach is clear, but those code blocks now take up aįew pages, so skipping over them to get to the real code is laborious. Objects, and I ensure that the object of interest has its code block at I haveĪbout 10 blocks of code that define the parameters for each of my 10 There are about aĭozen parameters that have to be set for each object.Īt the moment, I use global variables for these parameters. Think of itĪs if I want to create a family of crescent wrenches. You can use "r" for the radius or "d" for diameter.I have an OpenSCAD file that creates a family of objects. Here is the code for a simple cylinder 20mm in height and radius 15mm : "true" causes the prism to be centered on the axes "false" causes the prism to be drawn starting at one corner. Because the vector values are not the same, the "cube" is actually a rectangular prism. Here is the code for a cube that is 40mm on a side. This parameter is only needed for correctly displaying the object in OpenCSG preview mode and has no effect on the polyhedron rendering.Ī subtree is the code following a module call up to the next semicolon that is outside braces (" is required if there are statements after the subtree. The convexity parameter specifies the maximum number of front or back sides a ray intersecting the object might penetrate. Here are some vector values to be used for color In defining color values, the vectors are or. The most common vectors are or in defining shapes. You should change some of the code to experiment with it.Ī vector is a number of values between, as. Visualizations of the code are not included here in order that you might be inspired to cut and paste it into a running openSCAD to see how it looks. Facilitate the expansion of the tutorial by many users.Include things that a beginner might not know, but that a more experienced user would regard as "clutter".Each coding example uses things that have been described earlier in the tutorial. Include things in order of how they might be learned.This tutorial is not meant to replace the openSCAD manual, but to I prefer a tutorial on just one subject.A tutorial should be read from the top down, so the wiki format is better, IMHO. A blog lists later articles before earlier ones.This tutorial copies the information from the Thingiverse tutorial blog.
