Let OpenSCAD choose a zoom level for you.Īpart from zooming in and out you can also move and rotate the view of your model. Try zooming in and out using the corresponding icons. You can let OpenSCAD automatically choose a convenient zoom level by using the view all (third) icon in the same action bar.Įxercise Try moving your mouse over the viewport and using the scroll wheel to zoom in and out. Alternatively, you can use the zoom in (fourth) and out (fifth) icons on the action bar below the viewport. You can always zoom in and out by moving your mouse over the viewport and using the scroll wheel. In order to fix this, you can move your mouse over the viewport and scroll out until you can see the whole cube. In fact, it is large enough that it doesn’t fit in the viewport. The first thing that you should notice is that this cube is quite large compared to the previous one. Use the following statement to create a cube with side lengths of 25, 35 and 55. Did you remember to hit preview in order to see your changes take place?Ĭreating a slightly different cube Ī cube doesn’t have to be perfect. adding whitespace) or later when adding additional statements, you need to hit preview to see the effect of these changes.Įxercise Try changing the size of the cube to 20 and see what happens. Every time you make a change to your script (ex. When you hit preview OpenSCAD parses your script and creates the appropriate model. You just read "hit preview" three times in the last paragraph. What happens if you add whitespace between the syllables cu and be of the word cube and hit preview? What happens if you delete the semicolon? Is your cube created? Do you get any error message? Try adding some additional whitespace in different places and hit preview again to see what you can get away with before getting an error message in the console. Because a semicolon is used to indicate the end of each statement you have the freedom to format your code in any way you like by inserting whitespace.Įxercise Try adding some whitespace between the word cube and the first parenthesis and then hit preview. The semicolon after the last parenthesis indicates the end of this statement and helps OpenSCAD to parse the script that you have typed in the text editor. Any definition of parameters that a command may require is always done inside a pair of matching parentheses that follow the command word. ![]() The cube command is followed by a pair of parentheses, inside of which the parameter size is defined to be 10. The word cube is part of OpenSCAD scripting language and is used to command OpenSCAD to create a cube. There are a few fundamental concepts that you should set straight from the start regarding the OpenSCAD scripting language, especially if you don’t have a programming background. ![]() In order to create it you need to type the following code in the text editor and hit the preview (first) icon on the action bar below the reference axes. Your first object is going to be a perfect cube with side length of 10. You will be introduced to the available actions and you will use them as the tutorial moves on.Ĭreating your first object One final thing that you should notice is the presence of one action bar over the text editor and one below the reference axes. The bottom of the right column is the console, where OpenSCAD will be printing any error messages or other information as you build your models. The only thing that you should currently be able to find there is the annotated reference axes X, Y and Z. The top of the right column is the "virtual" 3D space where your models will exist. Any model that you are ever going to create is going to be "typed out" in this text editor. The left column is a text editor, where you will be typing the OpenSCAD scripting language to create your models. The first thing that you should notice is that the window of OpenSCAD is divided into two columns. To move on please install OpenSCAD and start from a blank model.īasic information about the OpenSCAD environment As you are following the examples you will be asked to modify and extend them as well as create your own models. This tutorial is a follow-along tutorial. According to this technique, simple objects can be transformed and combined in order to create almost any complex model. Models are created by utilizing a technique called constructive solid geometry. OpenSCAD is a solid 3D modeler that enables the creation of parametric models using its scripting language. 7 The cylinder primitive and rotating objectsĪ few words about OpenSCAD.6 Adding more objects and translating objects. ![]() 3 Basic information about the OpenSCAD environment.
