Hello,

You can send me the rvm file to debug if the rvm file do not
confidentiality.

本来准备上传到github上的，结果是上传不成功：

还是上传到百度云上先用用看：

Any suggestions?

Hi No.1,

你好！

现在正在改写程序，稍后会发布一个测试版本。

re: Make Helix Curve in OpenCASCADE eryar 2016-05-05 18:26

@liyunzhou

原理和这个类似，不过那几个类只针对二次曲线到B样条的转换。

re: Make Helix Curve in OpenCASCADE eryar 2016-05-05 11:03

@liyunzhou
OCC目前Geom_Curve中支持Bezier和B样条曲线，以及二次曲线，像圆，椭圆，抛物线，双曲线。

对任意的参数曲线，我觉得有两种方法：
1.可以参考二次曲线的类实现，从Geom_Curve派生，实现相关虚函数；
2.将你的参数曲线转换成B样条曲线；

re: Make Helix Curve in OpenCASCADE eryar 2016-05-04 22:54

@liyunzhou

要看下你的参数方程是什么样子的。

Hi,
你好！

记得原来看过文档说明是BRepAlgoAPI中的算法较新，BRepAlgo中较老。
功能上没有区别，都是实现Boolean Operation.

@hkrugertjie

Wonderful!

Of course, there is an automated way, that is use RvmTranslator in the Batch File, such as the RvmTranslator.bat does.

You can generate a XXX.bat file to run RvmTranslator, just give two parameters: Rvm file name(include path) and translator Type(STEP, IGES, STL, etc). You can write the batch file like this:
RvmTranslator "1.rvm" "STEP"
RvmTranslator "2.rvm" "STEP"
RvmTranslator "3.rvm" "STEP"
...

then run the XXX.bat.

Enjoy!

@hkrugertjie

You are welcome!

Kudos for your PML macro skills.

Current version have this functionality to translate multiple files one by one.

Yes, solidworks have problem for larges files. For solidworks I think it also support STEP files.

@Hkrugertjie

Hi Hkrugertijie,

I do not know the way to subdivide rvm file except manually select them. That is a known problem of RvmTranslator to export so big rvm file.

RvmTranslator4.0 now only can export text rvm file to 3D PDF, the binary rvm is not supported.

Hi ssj,

你好！

目前RvmTranslator生成的OBJ文件中是没有对象命名和层次结构信息。

你的OBJ文件是准备用在unity3d中么？

re: Open Cascade中的内存管理 eryar 2016-04-12 10:49

@zhaiht
Hi,
你好！

可以设置环境变量：MMGT_OPT，将其值设置为0，从而去使用系统的malloc之类的，而不使用OCC的内存管理机制。

我是不喜欢去污染system32的，最多可以把相关库的dll路径加到环境变量path中去。

这是第三主库Tcl/Tk没有配置正确导致的。

Hi me_hungry,

Yes, it is possible to set model color in PDF by RVM files.
The RVM contains color info.

@CWING

Hello Cwing,

Sorry, I have no tools to split RVM files.
You can export smaller RVM files from PDMS, such as a RVM file only include one SITE or ZONE.

Best Regards,
Shing Liu

re: RvmTranslator4.0 Beta Version is Released eryar 2016-03-29 19:12

@cwing

Hi Cwingz,

Thanks for your feedback.

The 4.0 Beta version of RvmTranslator only can translate text RVM to 3D PDF.

And your RVM files are too large for RvmTranslator, especially the binary RVM files. I think you can export smaller RVM file to have a try.

Best Regards,
Shing Liu

可以试试这个：

@远离颠倒梦想
扫略平面法向不一定与端点处切向量垂直，你可以尝试看看

re: Make Helix Curve in OpenCASCADE eryar 2016-03-16 19:31

@远离颠倒梦想
对平面的法向量没有要求，只要不与扫略曲线平行。

公式就在那螺旋线的参数方程中，仔细理解后就知道了

@oneOfHUSTCAD
嗯，如果用配置好的环境变量来启动例子，就不会出现这种问题了。

就像安装好的例子程序都是通过批处理文件启动的。

plane p2 0 0 0 1 0 0
mkface f1 p1 -1 1 -1 1
mkface f2 p2 -1 1 -1 1

Hello,

这个问题很好，说明你也在思考。

建议你仔细理解下“参数曲线曲面”的概念，就清楚了。

Qt使用起来非常简单，有MFC的基础就更加容易了。

我以前也是用MFC，现在用了Qt就不想用MFC。

re: Happy New Year 2016 eryar 2016-01-04 10:19

Hi liquanhai,

新年好！

兄弟一下子就把握住了重点。

那个命令窗口是用的Qt的QTextEdit实现的。
可以搜索下QConsole，目前支持Tcl, Python的命令处理，效果还不错。
