Thank you

More update ideas: perhaps an option to draw the line on the plane of a selected face? it would make drawing weird lines a lot easier.

Why not, but give an angle depending on what Trigonometric origin?
Originally trigonometric drawing or side of the longest edge of the selected face ?

@watkins said:

Perhaps I'm being a little dense, but why would you want to rotate the line after creation?

To creat a 3d polarline ! I think it's too complicated (not to develop, but calculate two angles in two different 2d plans). Or easier to rotate yourself after line creation.

polar grid....

Salut Malaise ! Qu'entends-tu par là ? what do you mean by this?

[MALAISE]

Salut Matt

Je pensais aux autres systèmes de coordonnées ( cylindrique, polaire )
Un maillage polaire au sens cartographique par exemple...

Merci de ton attention

Translation:
I thought to polar grid like the one found on maps.

Simple but powerful.

Thanks, I'm digging a big hole in anticipation of throwing out all my cad software.

Matt:

1st. Thanks!

2nd. Seems to have a problem. I typed in " 100**'** " and it drew a line 8'4".

  Perhaps the  %(#FF0040)[****'****]  character is the problem?

Regards, John

Hi ! I think This plugin doesn't support Feet / Inch units... I will have a look !

[Edson]

sorry, but it does not work for me on mac.

i click on the icon, it asks me to specify the first point, which i do. then a dialogue box appears for me to enter the length and the angle. i do do that and click OK. nothing happens!

what else should i do? any ideas?

[Matt666]

Hum... Another Pac problem!! Damned. I don't know what's the problem, and I've no mac... Can you copy here the error in the ruby console please ?
Thank you...
Matt.

[Edson]

here you have it.

[Matt666]

I don't understand the problem... Again !! Grmbl.
Can you try line below in the ruby console, please ?

Math.cos(45.degrees)

And these lines

a = Geom;;Point3d.new(12.5,12.5,25.2)
a[0]
a[1]
a[2]

On each line, can you give me the results, please ?
Thank you again for your patience, Edson!

[Edson]

is this what you wanted?

---

[thomthom]

Edson: you wrote 0 = Geom:: and 1 = Geom:: . That's not what he wanted. Just type exactly what he listed.

First:

a = Geom;;Point3d.new(12.5,12.5,25.2)

Then

a[0]

and so on.

[Edson]

is this it?

[thomthom]

Yes, like that.

[Matt666]

Thank you Edson and Thomthom !
I really really don't understand...

Can someone help me for this bug, please ?

[thomthom]

I can have a look on my own Mac when I get home.
Looks very weird. Does PC SU and MacSU use the same Ruby version?

Have you tried placing () around lg * Math.cos(ang) . (just a wild guess)

[thomthom]

Hey, I notice you use $lg and then lg. Is it suppose to be two different things?

I don't know, but I often have problems...

I will look in the code... Thank you!

[thomthom]

Got it nailed!

It's all down to line 69:

case Sketchup.active_model.options[0][2]

On my mac it returned nil

Your case switch doesn't account for that value so lg is passed on as a string.

case Sketchup.active_model.options[0][2]
    when 0;lg = result[0].to_f
    when 1;lg = result[0].to_f.feet
    when 2;lg = result[0].to_f.mm
    when 3;lg = result[0].to_f.cm
    when 4;lg = result[0].to_f.m
end

My fix was to add a default handler for the switch.

case Sketchup.active_model.options[0][2]
    when 0;lg = result[0].to_f
    when 1;lg = result[0].to_f.feet
    when 2;lg = result[0].to_f.mm
    when 3;lg = result[0].to_f.cm
    when 4;lg = result[0].to_f.m
    else  ;lg = result[0].to_f
end

Not sure why line 69 return nil though, didn't look into that.
