The "3D grayscale image BMP file 621" file is a bitmap file (.bmp or .jpg) in the BITMAP models section for self-creation in ArtCAM. 3D relief for CNC, wood carving, engraving, grayscale file, relief carving, scenery, models for ArtCAM. Vectors for CNC.
Attention!!! many files converted to Bitmap format (.bmp) with a size of 5000x6000 pixels (example) have a weight of up to 200-300 MB, so the files are placed in .JPG format (but with minimal compression). How to work with such files and create models in ArtCAM you can see in this article.
