Warning...
 
The new version has a serious bug in the 3D section. It will lock up the program (not the computer, thankfully) and generate a continuous-loop exception error.

This bug may only affect certain systems. I am running Linux Mint 13 x64 ("Maya") on a dual-core Athlon 64, with an nVidia GT520 graphics card. It may also be related to the version of JAVA; I'm using OpenJRE 1.6, but I'll try the newer 1.7 release and post later.

I had to update my graphics driver in order for the newest version to run, which needed to be done anyway. No problems now - other than the 3D feature is a bit of a resource hog.

OpenRocket "custom expressions"
 
Our club president, Tim C., sent me this "".ork" file which features "parabolic foreward fuselages" and "ogive aft fuselage," There are compaund nose cone parts, and nose cone rings, which I don't find in my version of OR (15.03, I believe).

I found that if I go up to "tools," I can click "custom expressions," but I don't see any of these above mentioned custom expressions. So how do I access them when I am designing my own rockets? I have tried.

When I click custom expression, a blank grau box appears, with a "new expression" button. I click that, in the upper left corner of OR, another balloon appears with multiple entries possible" expression, operator, varible, symbol, and units. if I place my cursor in certain boxes, a table appers with a list of functions and operators - but I am not sure how they work, what they do, how to use them, what order do I put them, etc.

Do I need to go back to school to learn programming?

Wow. Talk about reanimating an old thread.

I would say post the question on TRF. The Rocketry Forum has way more users familiar with the program.

Itís possible the creator of the file was using a version of OpenRocket after 15.03. There are unreleased test versions if you know how to compile them. A few of the beta testers have shared them. None have gotten bug free enough to release generally.

The file CarlosMC posted up there opens fine in the current release version of OR, It's a bit rough (the fins especially) but probably close enough.

I don't see anything custom in it, just an assortment of nose + transitions using standard options.
