Hi, I try to draw a torpedo (in fact a float of a boat). My problem is "how can I draw a surface between two different shapes. First, I tried manually to connect by lines the two shapes … a huge work, it must be a clever solution 🙂 I also used Sandbox but without good results ![](https://global.discourse-cdn.com/sketchup/original/2X/7/735d97dc0b69b6e532c4e257cba36ae96e0ccacb.png) [Sample in skectchup 2015](http://www.artcomputer.be/Sketchup/Test2.skp) Any idea ? Thanks, Philippe ---

Fredo’s Curviloft available from Sketchucation would handle that with ease… ---

Turning the shape upside down might make it possible to use the Sandbox from Contours tool on it, with some cleanup afterwards. It can be used as a basic lofting tool but it can only handle surfaces that are not vertical or with an inverse pitch. Anssi ---

or just use the move tool… rotate 90 degrees… move the top until it sticks to the bottom, then hold shift while pulling back to the start position… clean up… ![](https://global.discourse-cdn.com/sketchup/original/2X/a/ad8566f6c848b847a528694c562832d464a08651.gif) BTW: I don’t know how anyone can model in Parallel Projection… john ---

Tank you for your help. This is the final result (I have to clean some parts in the structure, but it’s ok) ![](https://global.discourse-cdn.com/sketchup/original/2X/a/a2144ef499d617e065d8aee09018f73dea29b636.jpg) BTW: I also changed the view to parallel (an old reflex from my previous architecture studies) 🙂 Philippe
