6、复制或者删除一个pad等模型时,经常会复制很多引用的组件或者删除时要提示一些不相干的元件。这是由于freecad的拓扑命名问题(https://wiki.freecadweb.org/Topological_naming_problem)。最佳实践是,不要在已有模型的表面上再新建草图。而是要每次需要草图时都以原始坐标系为起点,先创建基准面,再在基准面上画草图。
This is the second release candidate of FreeCAD 1.0. The most notable improvements over the 0.21 release series are the inclusion of the topological naming problem mitigation code, an integrated assembly workbench, a new materials system, and many UI/UX improvements. We expect to make three relea...
It may seems that we have yet to enter the main topic, considering the fact that the title of this article is calledTopological Naming, and we haven't actually talked about it. However, let me assure you the utter importance of the ground works described above. Because, only when you act...
First, version 1.0 finally implements a solution to the “topological naming problem”. Imagine you want to put a hole into a surface. The program needs to know on which surface to put the hole, and so it refers to this surface by name / number. Now imagine you subdivide the surface, ...
That is the infamous "topological naming problem". This issue is not unique to Freecad. Most parametric modelers have to deal with this issue in some way. In a nutshell, when you add, remove or slice sections of a model that has other sketches extruded from it, then all the surfaces ...
Cons Its a bit unrefined and buggy. I save often because on MacOS at least, it crashes occasionally. I've not had a problem restoring my work though. Review Source Incentivized review: software users are invited to submit an honest review and offered a nominal incentive for their time and ...

1.0.0 2fcc531 Welcome to FreeCAD 1.0! The most notable improvements over the 0.21 release series are: the inclusion of the topological naming problem mitigation code, an integrated assembly workbench, a new materials system, and many UI/UX improvements. ...
It's function now is to continuously improve and test the Topological naming problem and it's fix. Which I eventually plan to merge back in to the FreeCAD main branch.You can help test new features by trying one of the pre-built images released here. There is also more frequent release...
Let's take an example to see the new topological naming in action. We make a fusion with a simpleCubeandCylinder. Note that, I have turned off string hash in advance to show the raw topological names. You can do this by typing in the console, ...
