HOWTO Add Thrust Curve Files:
Want to add a new motor file (*.rse or *.eng)? Did it "dupe", "digest" into stock entry, or ignore? Here's how to KNOW that your file added and that it registered fully.
Here is where you add the ".rse" or ".eng" files on a Windows System: "C:\Users\<user name>\AppData\Roaming\OpenRocket\ThrustCurves\"
Note: To SEE the hidden "C:\Users\<user name>\AppData\" directory...
1) Go to "File Explorer --> View --> Options --> Change folder and search options.
2) On Pop-up Window "Folder Options", go to "View" tab, then down to "Hidden Files and Folders", and check "Show hidden files, folders, and drives".
3) Click "OK".
Faster Way:
- Open File Explorer from the taskbar
- Navigate to "C:\Users\<user name>\"
- Select View > Show > Hidden items.
ALTERNATIVELY, for ThrustCurves ONLY, you can use the OpenRocket "Preferences" to ADD a NEW VISIBLE "include" directory of your choosing. As I will also be adding component files, I will stick with putting them in the normally hidden ...\AppData\ tree.
When you download/save the file to the directory, edit...
1) the file name (so you'll know it is edited from clean download), and
2) the file content to REVEAL it is a NEW file in the software at runtime.
Let us look at the AeroTech I599N for instance:
Download Name: AeroTech_I599N.rse (
https://www.thrustcurve.org/motors/AeroTech/I599N/)
Edited Filename: AeroTech_I599N
_MINE.rse <--- I changed the file name so I KNOW it is MY edited (to guarantee a NEW entry) file.
Excerpt from file I edited (AeroTech_I599N_MINE.rse) RECOMMENDED**:
a) I edited the "mfg" parameter to "Aerotech-MINE" to guarantee a NEW motor entry.
b) I edited the "code" parameter to "I599N-MINE" so I can SEE/VERIFY the NEW entry.
c) I added some text to the "comments".
NONE of the edits change the "motor math".
Code:
<engine-database>
<engine-list>

** Software auto-magically generates a NEW Manufacturer Entry, which guarantees a NEW entry, AND gives you a way of ONLY seeing the thrust curve files YOU choose to add/see.

There ARE other potential options to accomplish this task, BUT....
WARNING: Not ALL changes in the motor file will result in a NEW entry. SOMETIMES it will temporarily create a new entry. SOME changes are not reflected at all, and SOME changes will be "digested" into the "stock" entry. The method above will guarantee separate entries.
