How To: Use the surface modifier in 3ds Max

The Surface modifier in Autodesk's 3ds Max generates a patch surface based on the contours of a spline network. A patch is created wherever the segments of the interwoven splines form a three- or four-sided polygon. The Surface modifier and the CrossSection modifier, taken together, are referred to as Surface Tools. They allow you to create complex or organic surfaces, like the fuselage of a plane, or a three-dimensional character.

How To: Add a Non-Stick Surface to a Cast Iron Skillet

Many cooks refer to well-seasoned cast iron skillets as the original non-stick pan. A cast iron skillet is a versatile piece of cookware, going from the top of the stove to the oven with ease, provided the handle is also cast iron. The secret to a non-stick skillet is in the seasoning and cleaning process. Improper seasoning, cooking acidic foods and incorrect cleaning methods can all remove the non-stick capabilities. Achieving and maintaining a non-stick cooking surface is uncomplicated and...

How To: Make Surface-Mount Electronics at Home for Smaller, Cheaper DIY Gadgets

Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.
