Since I have already created a file and made some entries there, you can use the file that I have attached in the mail.Step 2: If you are creating your own usertype.dat file, add one acis keyword per line.  This file is read during the Visual Studio initialization, so you will have to exit VS and then start it up again for the changes to take place and the syntax coloring mechanism checks the usertype.dat file last. Thus, all previously defined colorsettings take precedence over the user-defined keywords.Step 3: Now start VS (Visual Studio) and choose Options.  Select the format tab.  In the colors box, select User Defined Keywords.Step 4: Set the font, font size, foreground color and background color to your preferences.   Click OKStep 5: Restart DevStudio.-------------------------------------------Hope that helped.___________________________________________________Medicine meets Marketing; Dr. Swati Weds Jayaram.Rediff Matchmaker strikes another interesting match !!Visit http://rediff.com/matchmaker?2-------------- next part --------------A non-text attachment was scrubbed...Name: usertype.datType: application/octet-streamSize: 20568 bytesDesc: not availableUrl : http://lists.cs.columbia.edu/pipermail/acis-alliance/attachments/20030907/d9d5ba77/usertype-0001.objFrom SpatialDimensions at Spatial.Com  Mon Sep  8 15:51:42 2003From: SpatialDimensions at Spatial.Com (SpatialDimensions@Spatial.Com)Date: Mon Sep  8 17:01:29 2003Subject: [Acis-alliance] Insiders	=?utf-8?q?=E2=80=99_Summit=2C_May_3-5=2C_2004?=Message-ID: <OFA2C57A1D.A77E4AF3-ON87256D9B.00727DA4-87256D9B.007298B1@Spatial.Com>Spatial is happy to announce that next year?s 3D Insiders?

The conclusion is that the centroid is the average of the coordinate values. Please let me know if you have got different answers from others. Regards, Prashant Gupta -----Original Message-----
