First, you navigate to my projects. (Top left-hand side of your screen once logged in)
Once complete, either create a new project or click on one of your previously created projects.
Once you have either created a new project or clicked on an existing project, you will see the option to upload drawings top right side of your screen.
Once you click the "Upload Drawings" button, you will get the modal that will allow you to click and drop your files, or you can click and select the files you want uploaded.
