Hi! I have 2D CMM data mapping the inside of a pipe at a plane of interest prior to coating and coating thickness measurements at various points inside the pipe. I want to plot the CMM data, offset each wall of the pipe by its corresponding thickness, and use the offset data to calculate the coated cross-sectional area of the pipe (see diagram below). Is there a simple way to do this? If not, does MATLAB have a built-in function to offset the data by a uniform thickness (similarly to CAD software)?
