3Dplot问题——兼答 “mathcad不显示3D图像”

zpz77777

在PTC的mathcad论坛里，发现一篇讨论不同的系统乃至不同的硬件品牌对mathcad14~15的三维图像支持

的问题，从作者的实验结果，似乎不仅操作系统存在支持与否的问题，甚至连硬件系统也存在支持与否的问题

。现将它原文转载，供讨论参考：

Problems with showing 3D-plots
3D-plots wont show on some machines[/SIZE][/B]
===================================
Hi there

I know there has been post about this, but here we go again:
I'm in a math class, where some (mine inclusive) mathcad installations wont

show 3D-plots, as described in http://www.ptc.com/forums/viewtopic.php?t=7008

when inserting a 3D-scatter plot, a blank Square appears.
We have tried to isolate the problem and this is our results:

Lenovo R61i w/ win7 x64 ultimate - M020 (14.0.2.5) Error

Lenovo T400s w/ win7 x64 pro - M010 (15.0): Error

Lenovo w500 w/ win7 x32 ultimate: Error (older version)

HP w/ win7 x32 home: NO ERROR (older version, same as below

Lenovo T60 w/ win xp pro sp3 - 14.0.1.286 M011: No error

Mac running xp via vmware: no error

IBM t43 win7 x32 - 15.0.0.463 - error

T61p vista mathcad v 13 - no error

--------------
So as you can see it seems like the problem is Lenovo Laptops with windows 7

and MC14, which makes no sense?
Do you have any ideas on what the issue could be please let us know!

同样的电脑（所有配置都一样），一台安装win7旗舰版系统，一台安装win xp 系统，但是xp系统上能显示3D图像，而win7系统不能显示3D图像

就是有这种乱象，这恐怕只有软件的设计方才能给出准确的解释了。

是Windows7漂亮的透明窗口惹的祸，打开MathCAD执行文件的属性，并按下图设置：

另外MathCAD在Windows7下偶尔会有计算错误，不知道是什么原因！
