Micheal:

That's precisely why I highlighted the 2 lines in yellow in the attached pic. A triangle is the absolute basic container to describe a plane in 3d space.

I was expecting an "intuitive arc command" to recognize the 2 yellow sets of co-ordinate points, so the arc command would use that data to draw the arc in the correct plane. Any arc in 3d space needs some reference, otherwise its just guessing.

How does the Cplane deal with this attached pic?
Using my "intuitive arc command" analogy above, this is one way I could use to draw arc's
on planes of an inscribed tetrahedron?

So the bottom line is: I need v2?

This beta should be available for input from users, like me, that remember AutoCad v2.5 which came on
5 X 5 1/4 inch floppies, and the agony of trying to draw in 3d :)

thanks! Frenchy, your becoming my shadow! we have to stop meeting like this and elsewhere :)

there is no CPlane in V1
So helpers lines and rotate axis will be your rescuers :)

The arc command is expecting to use a plane to orient itself, not just a couple of line segments.

In v2 you can either draw a plane snapped on to those line segments and draw on that plane, or set a cplane there and then draw the arc.


> How does the Cplane deal with this attached pic?

It's not quite clear to me what you've got there in the model - do you have some actual planar surfaces there making the tetrahedron? If so then in v2 you can just draw the arc on those planes without even setting the construction plane.

It would help if you could post the 3DM model file with your stuff in it instead of only a screenshot, that will then let you show you with your specific example rather than trying to figure it out and reconstruct it (and possibly misunderstanding exactly what you have).


> So the bottom line is: I need v2?

Well, yeah - if you want to use the new stuff that has been added for v2 then you need v2.

Once v2 is released then there will be a trial version out for it.

Well, it is available to users like you! :) Just purchase v1 and use your v1 license key to get access to the v2 beta. The v2 beta is available to all v1 customers.

Here's one approach in V2 beta without using CPlane.

Hey good job Dan. Managed to get the old Commodore 64 out and load up MoI on it??? :o

Thanks Burr, actually it's a screen cap of my Timex Sinclair running an XP emulator. :P
(really compressed gif to 16 colors for the bandwidth challenged), in this case content
was more important than appearance. ;)

In that case, very impressive!! :o

Commodore 64.....thanks for dating yourself :-)

ps: I owned one after my Vic-20.

I started out with a Commodore 64 as well, I learned how to do assembly language programming on it, which came in handy later on!

I drifted away from computing for a while and then got into computer graphics with Amiga computers a while later.

>then got into computer graphics with Amiga computers a while later.

Hah, that takes me back - the Juggler!

I started out with a Commodore PET at school in about 1980, drifted away from computers then from 1989 I had an Amiga (a 500 with, eventually, a whopping 20mb HDD!). They were great little machines for the time, pity CBM never really invested in the platform. I learned a lot about DOS and shell scripts (I think I had some kind of bsh clone installed) as well as ARexx and basic C... That was when I was money poor and time rich. Happy days. The concepts I learned back then are still standing me in good stead today.
