conda netgen issue

Hi
I found that netten package version 6.2.2006 not install netten command tools. Due to I can't use FEM module. I check the package which installed on my conda/pkg/netgen-6.2.2006-py39h060e841_3/ . I found that the package not install netgen tools can used by FEM.

Re: 滑輪及螺絲

用轮廓(profile),先画个零件“正视图”的轮廓,之后将这个轮廓沿 Z 轴旋转,可以得到滑轮零件。

你画的东西不好加工。如果滑轮的凹下去的部分,用半圆的形状,这个也不好加工,在CAD中计算量也大。看你的实物,明显与你画的有出入。还是看看台湾清华大学关于《机械制图》的网上课程,对于设计与加工会有帮助。

如果按你画好图,加工零件的师傅会"高看"你好几眼的。:-)

关于翻译错误修正的拉票

首先声明,拉票这种事,本人不擅长,也不喜好。但 https://forum.freecadweb.org/viewtopic.php?f=23&t=59859 这个帖子中,对于中文翻译的错误修正,西人说要投票来修正。

为了中文用户的正常使用,现在中文坛子里拉个票,希望能及时修正这两处中文翻译错误。

Re: 什么时候出for arm64cpu的0.19版呢

ARM 64位的版本,可能有些难度。如果你是使用 conda 这种科学计算软件环境,来安装 freecad, 一般情况下,freecad 应可以运行。但有些工具, 如 ccx 或 gmsh 等,可能会有问题。可能这些工具使用了 Intel 专用的硬件加速指令,但 ARM 64-bit 上没有相应的指令。

Apple MacBook M1 号称使用 Rosetta2 函数库来转译两个CPU 架构之间的区别,但经我实测,现在还没有宣称的那么好,还有好多软件工具有问题。
