In my mind, designing and building your own CAD models are the missing links needed to seriously push 3D printing beyond the hype and make it go truly mainstream. Being able to download pre-made models is certainly fun and useful. You likely won’t find a bracket to mount a recycled can-opener motor to your Steampunk automaton project, on Thingiverse. Members of local maker spaces and robotics clubs dig 3D printing too, although they tend to like more techie-specific items like enclosures, cases, little brackets and technology related knick-knacks.Įven when I tell other techies that I routinely model parts in FreeCAD, they give me a slightly confused look. Enthusiastically, they’d go on about printing all their cool Star Wars helmets and miniature Transformers figures. The conversation often turns to 3D printing and several of the contractors, told me that they had 3D printers at home. I tell them I design and write about physical computing gadgets. Torq homestead over the last year, so I’ve talked to quite a few tradespeople. To scale objects use the scale method of the Draft module.We’ve done some renovating at the old Dr. See also: Autogenerated API documentation and FreeCAD Scripting Basics. → Draft → General settings → Draft tools options → Select base objects after copying. To reselect the base objects after copying objects: Edit → Preferences.→ General → Units → Units settings → Number of decimals. To change the number of decimals used for the input of scale factors ( introduced in version 0.20) and coordinates: Edit → Preferences.See also: Preferences Editor and Draft Preferences. The command can also scale Image Planes, but not in clone mode.Press Esc or the Cancel button to abort the command.The X, Y and Z scale factors will therefore be equal and will be set to the distance between the base point and the 'from' point, divided by the distance between the base point and the 'to' point. This will automatically check the Uniform scaling checkbox. Press the Pick from/to points button and pick two additional points in the 3D view to calculate the scale factors.For objects that are not Draft objects, or for Draft objects that do not have a Data Points property, this option must be selected. If the Create a clone checkbox is checked scaled clones of the original objects are created.The subelements must belong to Draft Lines or Draft Wires. If the Modify subelements checkbox is checked the command will use the selected subelements instead of the whole objects.This only works for Draft objects that have a Data Points property, such as Draft Wires. If the Copy checkbox is checked a scaled copy of the original object is created.If the Working plane orientation checkbox is checked the scale factors are relative to the working plane coordinate system, else they are relative to the global coordinate system.Check the Uniform scaling checkbox to lock the X, Y and Z factors to the same value.Enter the X, Y and Z factors to define the scaling.Press the Close button to abort the command.Press S to switch Draft snapping on or off.If global mode is on, coordinates are relative to the global coordinate system, else they are relative to the working plane coordinate system. Press G or click the Global checkbox to toggle global mode.It is advisable to move the pointer out of the 3D view before entering coordinates. Or you can press the Enter point button when you have the desired values. To manually enter the coordinates for the base point enter the X, Y and Z component, and press Enter after each.The single character keyboard shortcuts mentioned here can be changed. Press Enter or the OK button to finish the command.Pick the base point in the 3D view, or type coordinates and press the Enter point button.If subelements have been selected: check the Modify subelements checkbox to switch on subelement mode.If you have not yet selected an object: select an object in the 3D view.Select the Modification → Scale option from the menu.
