With best practice #3, keep in mind this is beneficial in 3D software that is parametric where it is typically used by engineers and architects for its use of specific dimensions and relationships, whereas explicit 3D geometry allows changes to be made on the fly and small changes are not necessarily related to any other defined point of the geometry. Watch the video for a visual definition of this concept. There are constraints for your abilities to change dimensions of the object, face, edge, vertice down the line of creation, so if you have these "modify" points you can choose that iteration of the model where you can effect the necessary manipulation instead of undoing tens or hundreds of steps or starting from scratch. Suggest copying and pasting model in one direction and at a constant variable (75mm, 100mm, 200mm) so that you create a "path" of the design changes the model goes through. Another helpful hint is to select your work at different "modify" points to give you an easier ability to "step back" to your model at an earlier design stage if needed.Another hint brought up in the video below is to create the dimensions of a small object (if that is what you are working with) into a multiple factor (enlarge it) to more easily adjust its features. And as you complete the object you can reduce it by the same factor to achieve the right size for your model. When a small object is near the (0,0) origin on the 3D grid, it has flexible viewing (zooming in) to select small surface features but if you place the object further from that point your viewing options will become less flexible. Considering 123D is prevalent on our Innovation Lab computers, keep in mind that working with small objects on the 3D plane could pose an issue as a small item is hard to navigate quickly. STL then consider saving it in a format that can be opened up in a 3D program that can handle both your saved format and save as an. If you are already comfortable in a 3D program and it doesn't have the ability to save or "export as" to. 3D program should have the ability to save in. To streamline your effectiveness in 3D model creation, here are some best practices to incorporate:
