So you can "Save As" version 10 format?

Inquiring minds want to know.

Cheers,


There's an option on the "Save As" dialog; it's not in the File | Menu per se, but in the actual "Save As" dialog on the far-right. There's a drop-down box which allows you to save in formats all the way back to Draw 7.

InkScape is Open Source (i.e. Free) and handles SVG just fine. The Gimp (another Open Source program) can read SVG but doesn't always do a good job with it. I've used both in concert, i.e. InkScape to convert the image to a bitmap, then Gimp to polish it, with good success.

I really hate to buy software, but that's a rant for another day.

I bought my copy of Corel Draw only because "He Who Cuts Out Our Fins With Death Rays" says his machine takes this format. That's good enough reason for me...

Likewise. I mean, that's just how the Krell draw things...

By "this format," do you mean SVG? SVG is the NATIVE format of InkScape, while it is an "export" for Corel. If I ever get the urge to have fins custom cut, I'll try InkScape first.

No, the native format for Corel Draw is CDR. His laser apparently can accept Draw 10 CDR files directly as input. It doesn't accept Draw 12 CDR files, however.

Lightbulb New Design: Nebula

This particular design called Nebula, and I have redone it several times. The forward fin set on this design does not help the margin much. I finally can up with a way to add clay nose wieght without drilling the nose cone. Clay can be added by cutting the main BT 1.5 to 2 inches aft of the BNC and add a balsa tube coupler at this joint. The clay can be added in the hollow BT section between the BNC coupler and the Balsa Tube Coupler . The 2D drawing might help better explain this method .

This design is inspired by a vintage sci-fi magazine cover called Nebula issue #27. It is an 18mm design and falls in the VR class of designs. All Semroc parts have been used.

Enjoy and Thanks Again, JP

Exclamation New Plan -- Sizzler

OK, so this is a tired name that's been abused too often. I figured I couldn't do any worse...

Length: 16.10"
Diameter: 1.04" (ST-10)
Fin Span: 4.04"
Weight: 1.13 oz

A8-3.......239'......Dv 6 FPS.......36" x 1/8" rod
B4-4.......521'......Dv 10 FPS......36" x 1/8" rod
B6-4.......525'......Dv 14 FPS......36" x 1/8" rod
C6-5......1045'......Dv 8 FPS.......36" x 1/8" rod

It's a simple build, and should be a good stable flyer.

Enjoy!

Exclamation New Plan -- Eclipse

Eclipse is 13mm powered and has reasonable performance for its size. I'm putting this one in the "Schoolyard Sounders" category.

Length: 16.70"
Diameter: 0.908" (ST-8)
Fin Span: 3.908"
Weight: 1.08 oz

1/2 A3-2T......113'......Dv 13 FPS......36" x 1/8" rod
A10-3T.........314'......Dv 16 FPS......36" x 1/8" rod
A3-4T..........319'......Dv 14 FPS......36" x 1/8" rod

May be one of my next build projects...

Enjoy!
