Looking good so far! I like the diamond and your block, Danny. It looks like some kind of weapon hardpoint or reactor vent.

I think your wedge could do with more detail though, pwhk.
However if we're going to have lots of custom sections I suggest an overhaul to the shipmaker's section selection system (alliteration!) so that it's easier to find what you want.
Option #1; Dropdown sheet
Hit a "select part" button and a big screen-size sheet appears. Scroll bar on the right. Click on a part to select it and place. You can then click the "place part" button to place again, or "select part" to pick a new one.
Option #2; As above, with categories
Add categories; "wedge", "internal", "external", "misc", etc. that can be selected from a dropdown box/list at the top of the parts sheet. This filters out all parts that aren't in that category so you can browse only wedges and so on. Each part can have multiple "tags" and thus fall under multiple categories. Ideal tags are general shape (eg; wedge), race (terran/alien1/alien2/other), author (stock/whoever) and so on.
