View without software
Your recipient opens DWG, DXF, IFC, STEP and PDF in their browser. In a drawing they turn layers on and off, browse the layouts and search the text. In an IFC model they click an element to see its properties and cut the model open with a section.
A DWG larger than 16 MB does not open in the browser; your recipient then simply downloads the file.
Measure in the drawing
In a DWG or DXF your recipient measures distance and angle, area and perimeter, and the radius of an arc or circle. The measuring line snaps to corners, intersections and midpoints. In an IFC or 3D model they measure the distance between two points.
You measure a PDF drawing in the PDF editor: at the scale you set, or calibrated on a dimension you know. Open the PDF editor
See who downloaded
Send a delivery by email and every recipient gets a link of their own. You see per person whether and when they downloaded, and a reminder only goes to those who haven't downloaded yet.
With a paid plan you also get a proof of delivery as a PDF for every delivery, with the files, the recipients and the downloads with date and time.
A fixed folder for each project
Give every project a shared folder with subfolders. When you upload a new version of a drawing, the previous one is kept as a revision. Your client needs no account, and you see who opened what.
