Hi Tom,
Thank you for your interest in Syncfusion products.
1. Beveled appearance for a WPF 2D pie chart
As suggested by you, we could use BevelBitmapEffect. Applying this to the Pie segments alone will change the appearance of the segments alone without affecting the legend or the ChartArea appearance.
Please refer to the sample in the below given link that uses a custom template for Pie segments that makes the pie segment to render with bevel appearance

2. 3D charts appearance to be similar as 2D charts
Currently we do not provide support for ' Edge lines and adornments for 3D charts '. This has been confirmed as a Feature Request.
We will implement this feature in our forthcoming new version releases or service pack releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. We will get back to you once the feature is implemented.
Please let us know if you have further queries.
Regards,
K. Saradha Devi
