Make a structural beam specification program which requires the user;
Opt for a construction type from 4 available types (a, b, c & d) from a single screen with large enough buttons to add fairly detailed icons.
If type c or d is selected then a new screen is to appear with two small areas for numerical input of up to 5 digits each. RLW(mm): xxxxx & Mass(kg)/m2: xxxx then proceed to the next screen.
If type a, b, c or d is selected the user will prompted to enter another two numbers of up to 4 digits in each. Opening(mm): xxxx & Height(mm): xxxx. This ends the users input.
The app will then select a beam size and length from one of the 4 tables depending on type selected and cross referencing users numerical input.
This "minimum member" needs to be displayed in two wheelie type lists which can then be scrold by user to "upgrade" the beam size and increase to length to longer available lengths. There are to be about 12 beam sizes each with about 12 set available lengths.
Once this has been achieved and artwork added, the app will need to have a "basket" and be able to re-run to add multiple members before proceeding to place the order.
The app needs to have an agreement at the commencement for legal liabilities.
I wish to have the screen wallpapers and icons and resulting beam size icons to be supplied later once app is functional.
All necessary information, tables, resulting beam sizes and lengths will be provided.
