Unfortunately I can not load the plugin on SketchUp 2018.
This is the error warning on startup:

With SU2018 cause the SU crash.

Good plugin. Thanks!

I just have any doubt with "Arc: 2 Points, Tangent":
I noticed that the arc is in line with the tangent when I run in CW direction, if not is in opposition, so if I have to draw an arc following the line running in CCW direction I have to overturn the point of view, and this is not always convenient or possible. Would not be better to reverse the sequence of points to click and double the function?
First any point of the tangent line, second the starting vertex of the arc and finally the point of arrival. Clicking "Arc: 2 Points, Tangent" the arc would be in sequence to the line and clicking "Arc: 2 Points, Tangent"+CTRL the arc would be in opposition. For example, on my SketchUp, I have a toolbarbutton to draw the angular dimension and with "TAB" I can change from the internal to the external value and vice versa.
I think in this way can be more logical and very useful, since the tangent function of the SketchUp button "Arc" does not always work (if the arc start from a vertex, if the tangent is a line of construction, or with the disturbance of other lines or points at the background).

Very useful plugin, would be perfect if the tool "Dimensions to Layer", creating a new layer, write on the "Name for the New Layer" window a default name, for example "DIM-TEXT", so, if I wont I can change it, but I don't have to write it every time.
Please, can you take me the rb file text modification to obtain this?

Thank you very much anyway for the plugin.

Now it works!

In the meantime I tried the plugin with a completely clean Skechup (except sketchup.rb of course) but I got the same result. Most likely the problem is the Italian version of SketchUp 8.0.4811.

Thanks a lot.

Marco.

If I past the code '25.0637705656528"'.to_l into the Ruby Console I obtain this answer:

'25.0637705656528"'.to_l
Error: #<ArgumentError: (eval):24:in `to_l': Cannot convert "25.0637705656528"" to Length>
(eval):24
(eval):24

The Unit setting that I use is "millimeters" and the error came also with the default dimensions (90°, 1000mm, 12 segments).
I have a big quantity of plugin mounted on my Sketchup and this is the first that don't works fine.
A bug of the italian version of SU?
Booh!

Good work but there is an error.

When I try to use "TIG.arcal" the Console Ruby report this:

TIG.arcal
Error: #<ArgumentError: C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/TIG-arcBYtools.rb:85:in to_l': Cannot convert "25.0637705656528"" to Length> C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/TIG-arcBYtools.rb:85 C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/TIG-arcBYtools.rb:85:in arcal'
(eval):85

I solved changing:

g.name='Arc_R'+((r.to_f.to_s+'"').to_l.to_s.gsub(/ /,''))+'_L'+a.to_s+'_A'+an.to_s

with:

g.name='Arc_R'+r.to_s+'_L'+a.to_s+'_A'+an.to_s

I don't know if is the right procedure but it works.
