Dear Patrick,

If you have Mathcad, you may already know it can produce 3d charts
Excel cannot (will it ever?).

Mathcad charting has its own limitations, too. But if its 3d charts
fit your needs, try the excel addin from the mathcad web site. It
enables you to get mathcad's 3d charts right on an excel worksheet,
plotting data from the worksheet.
