Tech Consultation Needed for developing an IOS - Layout Drawing App

We are looking for an experienced developer to provide a technical direction to develop an app where users can draw the layout to make organizers (which will then be cut and put together using acrylic) An IOS App where user can create layout for organizer for Box, Drawer or Tray and then export to Autocad file - which then a acrylic printing /cutting shop will use to cut the pieced and make an organizer based on the directions. Sample Design to understand the concept : [login to view URL] See attached an image of a Final output after designing > cutting > printing and making the box Points • Add a Layout ♣ Specify Length, width and Height ♣ Outer Layout is created ♣ Does it need outer border • Yes/No ♣ Specify No of Columns and Rows • Separate Zone and Add Box Area inside ♣ Specify the Zone or Partitions – Either by drawing or making specifically • Can choose full layout as one zone or select a specific area • Select Zones • Go inside zone o Select the Organizer partitions o Save • Save Layout • Export the layout to Autocad file – each piece will be separated as a square/rectangle blocks so that the printing team will print the pieced and join them together to make the box See the designs here to get an idea about the requirement: [login to view URL] - This is just drawing - what we need to achieve is the way where a user can open the app, select the type of drawing and then start doing the drawings. The app will then be able to convert the drawings to AutoCAD file using the specified length and height. The printing shop will cut this on Acrylic to put together and make organizer
