Similar to the estimator found in the Wall plugin the user will be able to select "All" or a selection of assemblies to run the estimator on:

The non-Medeek wall and roof assemblies will also be selectable since the Electrical plugin also works with non-Medeek walls, roofs etc...
I don't feel like it is necessary to break the listings into the assemblies they are part of however I will include a column in each table which lists the main assembly the electrical component is found in, this should prove useful to some.
There are a lot of little details with regards to different electrical components (ie. outlets, switches, panels etc...) Each type of electrical component has unique characteristics, all of this data needs to be output by the
Electrical Estimator, it will probably take me a few days to assemble this new module.
Once it is complete it will make this plugin a much more useful tool.
P.S. I think it would be also quite useful at some point to incorporate a price database that works with the estimating module. This separate database would be referenced to determine the price, vendor etc... for a given electrical component. Additionally, the list of materials could then be conveniently broken into separate purchase orders for each vendor. I'm probably getting a bit ahead of myself here but with the ability to program just about anything with the API and the Ruby back end its conceivable that one could generate PO's that could then easily be imported into Quickbooks or any other accounting software. I've done a bit of Quickbooks API programming in the past where I integrated my own customer billing system and expense database with the software, its really not that hard to do.
When I ran my web hosting company back in the early 2000's I got really sick of having to manually enter in customer orders and business expenses into Quickbooks, the problem was my billing system and Quickbooks (my accounting system) were completely two different ecosystems. I would usually have to devote one entire day out of the month for this tedious task. I finally got smart one day and decided it would be really nice if I could somehow automate this process. After about two days of programming I had fully automated the manual entry problem and set it up as Chron job that would run nightly, it would even shoot me out an automatic email every morning letting me know how the process went and if there were any issues.
