why I can not use "Surface plot"

why I can not use "Surface plot"

why I can not use "Surface plot"

Dear all:

If I click the "surface plot", the CPU will run to 100%, and then Mathcad is closed suddenly.

I tried it in an empty sheet, it happened again!

I do not want to reinstall it, because I need to tell the Administrator what happened and then....and then.....It will take a long time.

If anybody here can have experiences about how to solve this problem???

Thank you very much in advance!

RE: why I can not use "Surface plot"

I have not seen this problem, but to have any hope of getting an answer to something like this you should include the version of Mathcad (including service pack) and the version of Windows you are using.


RE: why I can not use "Surface plot"

You might need to disable the graphics card acceleration.  Mathcad, for whatever reason, is quite finicky about graphics card performance.

RE: why I can not use "Surface plot"

We had a few issues running Mathcad 14 on Windows XP without SP2 installed. One of the common symptoms was inability to use the 3D graphing tools.

Suggest you check whether you have Windows XP SP2 installed, and if not, install it, and then reinstall Mathcad, if necessary.

Hope this helps!

RE: why I can not use "Surface plot"

Hi guys:

Thank you all very much!

I am running Mathcad 13.0 in Microsoft Windows XP Professional Version 2002 Service Pack 2.

RE: why I can not use "Surface plot"

This is from the Mathcad knowledge base for MC13.  Also you should upgrade to MC 13.1 when you get the chance.


Problem: Mathcad crashes, freezes, or locks when rendering a 3D plot.

Cause: This problem typically stems from a video card driver having trouble rendering the OpenGL graphics used in Mathcad's 3D plotting.


   1. Update your video driver by downloading and applying the most recent driver from the video card manufacturer's website.
   2. Turn the Hardware Acceleration down or off: Right click on your desktop and choose Properties (or from the Start menu choose Settings/Control Panel/Display.) Go to Settings/Advanced and click on the Performance Tab (in Windows 2000 choose Troubleshooting). Use this setting to decrease Hardware Acceleration.
   3. Change the color depth since some cards are designed to perform better at certain color depths. Right click on your desktop and choose Properties (or from the Start menu choose Settings/Control Panel/Display.) Go to Settings, and in the Colors field adjust the setting up or down.


ATI's Radeon cards and drivers:
With ATI's Radeon 7000 card and Catalyst driver 3.5, turning down the Hardware Acceleration works. Otherwise, using the Catalyst 3.4 driver works. This information may apply to other ATI video cards and drivers as well.

Intel 810e video chip:
Turning the Hardware Acceleration down or off works with this chipset.

In addition to the recommendations in this article, please see this Knowledge Base article, http://support.mathsoft.com/mcad2001i/article.asp?id=667.

S3and S3
Diamond hybrid video cards: With these cards, typically the only solution is to turn Hardware Acceleration down or off.
