This 8.8 cm anti-ship cannon was developed for use on Type VII u-boats during the Second World War. The model was developed from photographs with only the diameter of the bore as a guide. It was created in AutoCAD Version 14 and is a complex wire frame. This type of construction can be time consuming since you must develop a frame for all sides of the box. Wire frames cannot be solprof out to 2D drawings. These models can be constructed and offered to clients for download for placement purposes without divulging construction information.
