If you make a scan of it and save it as jpg or png you can upload it. If you have this, and you created a plan, click on the most right icon in the construction menu where you can upload it.

kind regards,

My problem is not solved. As I have uploaded one plan succesfully but unfurtunatly the wrong one and the system did not accept to delete for a new upload. Is this a feature not available to the free version?
Thank you
