In its current state caclulating features are based on property scripts.
Although not bad its difficult to maintain and develop. Also difficult to create cost estimations. So here are some wishes to make it better, without altering all its structure.
1. Property scripts SHOULD be able to include property scripts.
For example i could have a scipt name insulation with xxx material
one with "brick XxY wall" one with coating.
And the overall script will be an assemby of scripts. That way we could not repeat entries in property scripts and create much more complex and readable scripts
2. Each material should be linked to a database of products with prices.
The user can add edit products and prices.. and link them to materials.
