#### An Analog Clock Model – video preview

This is a video preview of the analog clock series which include a model section and a tutorial section.

#### Longitudinal Aircraft Dynamics #5 – finishing the aircraft

This section finalizes the aircraft (glider) by inserting the wing, the horizontal stabilizer and a center of gravity (CG) sprite in the layout.

#### Longitudinal Aircraft Dynamics #4 – virtual aircraft definition

This section of the tutorial explains how to create the  2D aircraft components for the animated longitudinal stability model. The first part deals with extracting the x-y coordinates for the fuselage, canopy, vertical stabilizer and rudder. The second part handles the main wing airfoil and the horizontal stabilizer airfoil. All thses parts will be put together in the next section.

#### VertX – a Very Useful Macro for Extracting the Vertex Coordinates of Freeforms – part #2

The first macro created in this section of the tutorial improves on the previously developed macro by correcting the up-down orientation of the shape, referencing the shape position to the coordinate of the first drawn point and closing the shape by repeating the coordinates of the first point at the end of the table. A last macro is then created which can retrieve multiple shape vertex coordinates, placing them in a table…

#### VertX – a Very Useful Macro for Extracting the Vertex Coordinates of Freeforms – part #1

Using autoshape freeforms is a very easy way to duplicate object outlines from pictures. It is convenient to create a freeform and once created, its vertices (points) can be edited with without difficulty.  Aditional points can be inserted and others can be deleted. This is a tutorial about a series of macros which allow the extraction of freeform vertex coordiantes to a worksheet range in Excel. These coordinates can be later employed to create 3D wireframe…
