Adding Moveable surfaces to Clearview using Blender

I had succeeded in giving moveable surfaces to my small Su-37 plane based on Ken's import from FMS.

I started with a Firebird2, my only real expereince with flying, adding a moveable propeller.

Blender is well equipped although very quirky in its user interface.

The main problem is with the import and export of ac3d files. It cannot import ac3de groups but can export its parent relationship as groups.

In Blender, use the parenting facility, not grouping.
In creating nested groups requird by Clearview, make the XYZGroup into a group by choosing one of the member as a parent first.

You can duplicate this group by first selecting all members, including its parent. Not enough to just select the parent.

When combining with the moveable surfaces, select the parent of the XYZGroup first(its name will be one of the member, such as Then select the moveable surface to be combined with, then ctrl-P in order to for a grouping.

Blender does not allow dupilicate file names, even in diffrent groups/parenthood.

Blender can append from existing blender files of 3d objects as a library input. I used this facility to import an XYZGroup from Clearview's 25% edge.

After all this has finished, you need to select all objects, before exporting to ac3d files.

We must do a lot of text editing in order to rename the XYZGroup names from the member's name in Blender, and to remove extra .xxx added by Blender into 3d object names which have similar names as other groups.

Using ac3d will be much easier but Blender is free.

One final note: Clearview does not accept Ruder1 or duplicate Ruder names for the 2nd rudder for the Su37. We must use Ruder2. Note the case and misspelling of the names. Clearview is sensitive to case when it needs the names to be manipulated such as in implementing the moveable surfaces.

Clearview is supposed to be equipped with elevon, which is important for the Firebird 2, V-tail control surfaces but not sure how well it goes.

Next, I'd like to implement Nelson's Su27 moveable tail control surfaces, as Elevons.
