I am a CNC Programmer using MasterCam X9 in the aerospace industry for last 30+ years. I just started to use SketchUp for personal use. I plan on using it to make slides/videos for PowerPoint programs. I teach at our church and I use these PPTX presentation to show some concepts that are hard for some to visualize. They say a picture is worth a 1,000 words.I am a CNC Programmer using MasterCam X9 in the areospace industry.
