Uploading CADdocs with Relationships from local PC to ARAS

Hi All, looking to create a method to allow me to upload CADdocs into Aras, from my local computer, without needing to use a CAD Connector. I am new to developing for Aras and could use some pointers. Does anyone have any ideas or could lead me down the right path to get something started.

I'm envisioning a form where I select the top-level assembly and its children from a folder on my desktop and upload them into Aras. Any help or tips are appreciated!
