How to create a model group for laser engravers? with vector files (.svg, .dxf, .cdr, .ai, .lbrn, .studio3, ...) other than ".pdf" which are not downloadable directly in the model pack ( you have to take them one by one from the list of files in the model group), because currently https://www.crealitycloud.com/create-model only seems to be designed for 3D .stl models and do not allow to upload vector files (.svg, .dxf, .cdr, .ai, .lbrn, .studio3, ...) other than ".pdf"  Thanks.
