Thanks to Barry Briggs for doing this and sending me the updated source.en-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/danlehen/archive/2006/02/11/530361.aspx#545974Wed, 08 Mar 2006 10:58:20 GMT91d46819-8472-40ad-a661-2c78acb4018c:545974JohnHi Daniel, <br> <br>How are you doing?I'm John. <br>I've currently built my app on generating 3d charts, but all of this are hard coded. I wanted to make use of the feature of Avalon on binding on dependency properties. <br>Anyway, Do you have a simple app that I can reference to, It would really be helpful for me. What I'm planning to do is extend ModelVisual3D for each bar in a graph then binding these properties to a source. <br> <br>I also had problem accessing the &quot;Extending Visual3D - Sphere, Cone, and Cylinder&quot; sample. <br> <br>Thanks, <br>Johnhttp://blogs.msdn.com/danlehen/archive/2006/02/11/530361.aspx#545976Wed, 08 Mar 2006 10:58:37 GMT91d46819-8472-40ad-a661-2c78acb4018c:545976JohnHi Daniel, <br> <br>How are you doing?I'm John. <br>I've currently built my app on generating 3d charts, but all of this are hard coded.
