Well, the ET is made from the SLWT SDH published by LM in December 1997, 2 months before the first SLWT was transported to KSC.

Yes, and in which coordinate system are the SDH coordinates?

Where it concerns both the ET and the Orbiter, it gives the coordinates in both systems.
 
If anyone can get closer, good luck. I'm finished modeling this and will concentrate on the attachment positions of the KU, RMS, Airlock etc.

Let me know if you need coordinate graphics for the Ku.
 
So far I have an RMS shoulder center location of Xo 679.50, Yo -100 and Xo 589 Yo 100 for the KU post center.

Ku is correct and so is the RMS shoulder joint. The MPMs are 911.05, 1189 and 1256.5.

Can you verify that the center of the Ku band dish is at Xo649 and the center of the alpha/beta gimbals at Xo629? That should place the critical gimbals at the correct coordinate when deployed which is Yo135.
 
I've added updated longeron bridgerails permanently to the Airlock.

Airlock center is 649.0

Airlock center is 649.0
That is correct according to the NASA/Boeing/USA Shuttle Orbiter /Cargo Standard Interfaces document. Top the ODS with the ring retracted is Zo460.00. Fully extended is Zo479.76 while the Ready To Dock position is Zo475.51.

I just gave the latest orbiter mesh and check over and everything is GO, except for the submerged airlock/ODS, Ku and RMS. But once those have been fixed, I see no reason not to use it for the actual V3 release. We just need textures for the rest of the fleet.
 
What are the attachment points, of the those attachments ?

The Child attachments ?

They don't use attachments, they're just offset meshes where the offset is either preset in the meshes (Ku and RMS) or the offset is set in the code. Only actual payloads use attachments and these elements are considered both by us and NASA as orbiter hardware.
 
So how are they moved ?

How do mean? Do you mean how are they positioned correctly? As I wrote earlier: Two methods: Preset positions where the mesh is already positioned at the correct location (the Ku, RMS and ODS uses this method) and the code has the offset as 0, 0, 0.

The second method is centering the mesh and setting the offset directly in the code, this is the method that the starboard MPMs and external airlock uses.

Donamy: I hope you don't take this the wrong way but I fixed some issues with the Xo1307 bulkhead, the EVA winch hooks and the PLB sill longerons.

If you want the fixed versions as simple drop-in replacements, you can grab'em here: https://dl.dropboxusercontent.com/u/24122088/Fixed_PLB_sills_aft_bulkhead.ac
 
I'm not taking anything the wrong way, but when you import a .msh into AC3D, all the vertices are unwelded and nulify the crease settings. We are going to have major problems with shading and distortions just like before.

Understood. Maybe you could use it as a guide?
 
What did you do exactly ?
 
What did you do exactly ?

  • Moved the aft camera PTU/stands to the actual cameras
  • Closed the gaps between the 1307 bulkhead and the PLB wing box
  • Moved the aft EVA winch handle to the actual winch drum
  • Resized the FWD/aft EVA winch hooks by 200% as they were too small
  • Moved the inboard edges of the PLB sills so that they meet up with the PLB ring frames
  • Moved some of the "mesh-spheres" on the 1307 bulkhead to their correct locations on the texture
That's all the changes. FYI, the 1307 bulkhead texture came from here: http://www.nasa.gov/externalflash/sts-rec-panoramics/OV-103-Payload-5.swf
 
Ok, I wasn't sure what I was looking for. I noticed that there are quite a few double faces that need attention, (something I didn't notice from before).

Lets get this released, then we can do some repairs later.
 
Added the sill fixes DaveS requested. Also added an EVA PFR holder, a small handrail, on both sides of the front sill and a texture for the EVA winches. Cameras now in real life positions with exact pan and tilt points, among other tweeks and unseen face deletions.

Could you move the sill gussets a bit inboard? The vertical part is located right on the very edge of the sill.
