如何建模设备？
我正在寻找一种为我想从头开始制作的设备创建3D模型的方法，并能够可视化其尺寸。
我尝试使用Blender之类的软件，但我认为这不是这样做的最佳方法。
我想要的是建模，看看电路板是否适合模型内。
任何帮助都将不胜感激。
I am looking for a way to create 3d model for a device I want to make from scratch, and be able to visualize its dimensions.
I have tried using software like blender, but I don't think its the optimal way of doing this.
What I want is to model, and see if the circuitboard will fit inside the model.
Any help will be much appreciated.

我对所有这些都很好运：Sketchup，Fusion 360，Rhino，Dimbibre
都有（有？）免费选择。 Sketchup可能是最容易选择的。融合包括一些集成的凸轮工具，如果您要进行一些制造。
如果您要一起玩适合的零件，我建议使用参数模型（Fusion，Dibribre）。这使您可以使用参数创建模型，例如“此框比里面的部分长2 mm”。然后，当您更改内部的零件时，盒子将神奇地更改以匹配。
没有参数，每次更改一部分时，您都必须手动更改另一部分才能匹配，随着模型变得更加复杂，这将变得巨大的痛苦。
I've had good luck with all of these: Sketchup, Fusion 360, Rhino, Alibre
All have (had?) free options. Sketchup may be the easiest to get going with. Fusion includes some integrated CAM tools if you're going to do some fabrication.
I recommend a parametric modeller (Fusion, Alibre) if you're going to be playing with fitting parts together. This lets you create your model(s) with parameters, such as, "This box is 2 mm longer than the part inside." Then, as you change the part inside, the box will magically change to match.
Without parameters, every time you change one part, you have to go manually change the other part to match, which becomes a HUGE pain as your models get more complex.
