Line Interpolater is a simple tool that helps you compute the points you need for input of an airplane geometrical description to an engineering analysis program. One frequently has a line in 3D defined by two endpoints. But additional points on this line are needed for input. You may know one of the coordinates, but need the other two. Sometimes, you know the fractional distance of the point between the two defining points. This tool helps you get the numbers you need without laborious calculation.

On the left side of the screen are six boxes for entering the (x,y,z) coordinates of two distinct points that serve to define the line. On the right side of the screen are four input boxes that are set up as a radio group - that is, only one is actually active. When you click the Compute button (or press Enter), the point on the line corresponding to the active coordinate is used to determine the remaining unknown coordinates.
