Spiral hepta 2D design

Spiral hepta 2D designHere you can download Spiral Hepta 2D Design. We drew it on the basis of a Celtic triskelion symbol. This is a very simple but interesting geometric pattern which can be downloaded as a 2D CAD sketch (dwg file format) or as a vector (eps and svg file formats). It consists of a central spiral around which 7 more spirals are distributed. If you like this geometric pattern, but you need a larger or smaller number of spirals, you can modify it in any CAD or vector software. It is only important to download the appropriate file format, so it can be easily imported and edited.
