Hi robust,

對LGPL協(xié)議的理解我也是從網(wǎng)上獲取相關(guān)信息，你可以直接在網(wǎng)上搜索下LGPL協(xié)議的授權(quán)相關(guān)注意事項。

你關(guān)注的這個問題在OPEN CASCADE的官網(wǎng)上也給了明確回復(fù)，可參考：
http://www.opencascade.com/content/faqs

3) Can I use Open CASCADE Technology to make commercial products and to sell them? If yes, are there any limitations?
Yes, you can use Open CASCADE Technology (OCCT) libraries in commercial applications without having to pay any development license fees or run time fees or royalties.

@ccsdu2009
這個東西我也不太理解，只是一個程序里面可能會用到。

你可以google看看voronoi看看這個東西的應(yīng)用，應(yīng)用還比較廣泛的。

@li yuan
嗯，最新版本的AutoCAD也沒有直接支持VB生成的宏，才用這個開發(fā)了下。

這個小程序是與AutoCAD的版本有關(guān)。

@siddharthmanek@gmail.com
Hi Siddharth,

Do you mean 3d pdf?

@bangzhuqiao

Hi,

你好！

目前這個程序還沒完成。

Best Regards,
Shing Liu

不知道來武漢了啊！

@舒米勒26號
稍后準(zhǔn)備下，放到github上

@舒米勒26號
看來AutoCAD .Net的兼容性也不是很好啊！

程序很簡單的，準(zhǔn)備開源出來，自己編譯吧

@SEDC
程序是使用AutoCAD2012編譯的，看來不支持AutoCAD2010.

AutoCAD 32位和64位都是支持的。

@舒米勒26號

可以試下最新版本cad2pdms1.1

你用的AutoCAD是什么版本？

Hi Ahmed,

You are welcome.

@LI
不客氣。

建議你還是先把triangle編譯出一個exe，仔細(xì)看看相關(guān)命令選項，
如"-a"就可以設(shè)置最大面積約束；

再把你的數(shù)據(jù)放到文件中，再用那個exe程序帶不同的選項來試試看。

@LI

你好！

那些參數(shù)是三角剖分的輸入數(shù)據(jù)。

控制剖分行為的參數(shù)設(shè)置是在結(jié)構(gòu)體behavior中：
/* Data structure for command line switches and file names. This structure */
/* is used (instead of global variables) to allow reentrancy. */

struct behavior {

/* Switches for the triangulator. */
/* poly: -p switch. refine: -r switch. */
/* quality: -q switch. */
/* minangle: minimum angle bound, specified after -q switch. */
/* goodangle: cosine squared of minangle. */
/* vararea: -a switch without number. */
/* fixedarea: -a switch with number. */
/* maxarea: maximum area bound, specified after -a switch. */
/* usertest: -u switch. */
/* regionattrib: -A switch. convex: -c switch. */
/* weighted: 1 for -w switch, 2 for -W switch. jettison: -j switch */
/* firstnumber: inverse of -z switch. All items are numbered starting */
/* from `firstnumber'. */
/* edgesout: -e switch. voronoi: -v switch. */
/* neighbors: -n switch. geomview: -g switch. */
/* nobound: -B switch. nopolywritten: -P switch. */
/* nonodewritten: -N switch. noelewritten: -E switch. */
/* noiterationnum: -I switch. noholes: -O switch. */
/* noexact: -X switch. */
/* order: element order, specified after -o switch. */
/* nobisect: count of how often -Y switch is selected. */
/* steiner: maximum number of Steiner points, specified after -S switch. */
/* incremental: -i switch. sweepline: -F switch. */
/* dwyer: inverse of -l switch. */
/* splitseg: -s switch. */
/* nolenses: -L switch. docheck: -C switch. */
/* quiet: -Q switch. verbose: count of how often -V switch is selected. */
/* usesegments: -p, -r, -q, or -c switch; determines whether segments are */
/* used at all. */
/* */
/* Read the instructions to find out the meaning of these switches. */

int poly, refine, quality, vararea, fixedarea, usertest;

最小角看字面應(yīng)該是：minangle
最大面積是：maxarea

@SDFSDFSDF
maybe...

官方文檔上面：Bottom of Pipe (BOP)
意思就是管底么。

@SDFSDFSDF
經(jīng)過測試，BOP得到的的確是中心坐標(biāo)，不是管底坐標(biāo)。

看來這個屬性有問題，與文檔描述不符，要么是用得不對。

@SDFSDFSDF
你確定用的是PBOP？

@谷粒OO

厲害啊！

看樣子有時感覺也很重要。^_^

@gopi

Hi gopi,

Thanks for your feedback.

RvmTranslator is used to translate the geometry model in RVM files, because the export result are STEP, IGES, STL, .etc format, such as STL only contains model mesh, do not contains assembly info, so if you want to export as a multiple entities, will be result many files per entity.

Best Regards,
Shing Liu

@fast

哦，剛google運(yùn)十了解了下，可惜啊！

@佚名
Hi ,
你好！

你可以調(diào)用Camera的SetZRange()或ZFitAll()試試看。

@zhx
Hi zhx,

這些aPoint是邊上的點啊！

你的邊上點的原始坐標(biāo)值是什么意思？

Best Regards,
Shing Liu

@佚名

有效果就好！

客氣了。

@佚名

Hi 佚名,

你好！

occ6.8之后引入了Camera類，你可以嘗試下在處理鼠標(biāo)事件的地方自己來調(diào)整camera，而不用occ的view中的旋轉(zhuǎn)函數(shù)。

Best Regards,
Shing Liu

@Mohamed Auswath Khan

you are welcome.

Translate model to STEP format maybe a little slowly, but translate to other format will be fast.

@佚名

Hi,

你好！

DRAWEXE依賴Tcl/Tk，occ的三維目前是用OpenGL顯示，沒有依賴DX3D的。
如果Tcl/Tk的庫沒有找到也可能報這種錯誤。

occ的做法是用批處理配置好環(huán)境變量后用draw.bat來啟動Draw的，可以參考下這種方式。

@Mohamed Auswath Khan

Hello Mohamed,

There are some notes about using the RvmTranslator:

For the Input RVM name, if the RVM file is not in the RvmTranslator folder, you should input the full file name include its path, such as d:/rvm/pipes.rvm;

For the Output file format, you should select one of the following: STEP, IGES, STL, all the type must input in uppercase letter.

I upload the RvmTranslator2.0, it supports Text and Binary RVM file, you can download to have a try.

Enjoy! :-)

Shing Liu

@MOhamed Auswath Khan

Hi Mohamed,

Thank you.

I hope the application will be useful.

I will release the first version of RvmTranslator soon,
then you can download it and have a try...

@MOhamed Auswath Khan

Hi Mohanmed,

I will develop a standalone program to export PDMS model to STEP, IGES, STL .etc. by rvm file. The standalone program will have no relation with PDMS, no matter which version of PDMS you use, only rely on the rvm file exported by PDMS.

Best Regards,
Shing Liu

@孤獨劍
Hi,

你好！

那就是必須的第三方庫沒有正確配置導(dǎo)致的錯誤。

如果是用opencascade安裝包來編譯，安裝完成后，根據(jù)編譯器及平臺修改下custom.bat后，直接運(yùn)行msvc.bat編譯即可一次成功。

Best Regards,
Shing Liu

@MOhamed Auswath Khan

Hi Mohanmed,

You are welcome.

Thanks for your attention, I will update the ModelDataExchangeAddin to 12.1 soon...

Best Regards,
Shing Liu

@MOhamed Auswath Khan

Hi Mohanmed,

Thanks for your feedback. I am very happy that the addin can do something useful.

The Addin can export the SITE or ZONE if you select it, but the
export process maybe a little slowly.

I will check the addin v1.2 for PDMS 12.1SP4.

Best Regards,
Shing Liu

@gsnake

Hi,

郵件已發(fā)，請查收。

Hi pdms,

you can download the Addin to check its license.
The Addin is free.

@qwerty

可視化模塊加載失敗。
可能原因是與可視化相關(guān)的第三方庫的dll沒有找到等

看上面的報錯，應(yīng)該是沒有正確配置所致。

@leo
Hi leo,

你用過ModelDataExchangeAddin V1.1么？配置成功過不？

@付振宇
Hi 付振宇，

你好！

請仔細(xì)看看這段話：

~~~~~~~~~~~~~~~~~~~~~~~~~
下載到源程序后，如果是Windows操作系統(tǒng)，還需要在triangle.h之前做些配置，如定義以下幾個宏：
#define REAL double
#define ANSI_DECLARATORS
#include "triangle.h"
#undef REAL

在triangle.c中定義宏：#define NO_TIMER。有了上面的宏定義，可以編譯出一個triangle.exe程序了。如果要將triangle用在自己的程序中，還需要定義#define TRILIBRARY。
~~~~~~~~~~~~~~~~~~~~~~~~~~
這些內(nèi)容加在tricall.c中，再編譯試試看。

你可以看看makefile，里面有些選項的。

Best Regards,
Shing Liu

@leo

Hi leo,

你是用的哪個版本？是ModelDataExchangeAddin V1.2這個版本不？
12.1需要用這個版本的。

Best Regards,
Shing Liu

在OpenCASCADE文件夾：
dox/dev_guides/debug/occt.natvis
已經(jīng)提供了一個natvis文件，不過里面的內(nèi)容比較少，感興趣的可以豐富一下。

@ly
一般一般

Cool!
