[Plugin] Angular Dimension
-
Hi,
test's fine here, I'm not sure what was up with the original icons, they work when I stuck them in a Toolbar button, but not as a cursor,
I know when I scaled mine down 50% to 16x16 they stopped working, so maybe there's a minimum file size?

Hi
How to switch from inner angle tool, which looks like is defoult, to outside angle tool?
-
After activating the tool, read the message line at the bottom of the drawing window.
You can also find the usage instruction at the beginning of the rb file if you open it in a text editor.

- The TAB key toggles between drawing the interior (<180) angle
and drawing the exterior (>180) angle dimension. If you press tab
after an angle dimension is drawn but before picking the first
point of the next angle, the current angle dimension will be
redrawn in the new mode.

Thank you for "TAB", now al works, I could not find that

Uhm, please forgive me if this is a 'duh' question, but I can't seem to get the draw_angle_dim.rb tool to work at all... Running WinXP Pro, SketchUp 8 Pro 8.0.11752.
The icons don't show up, I don't see it on the Plugins menu... how do I activate the tool??
Unfortunately, I don't know much about Ruby, but did try typing DrawAngleDimTool::IN_ICON into the Ruby Console and it does return the correct path and icon file name...and the files are there...
DrawAngleDimTool::IN_CURSOR returns 50001Help?

The most common reason that plugins don't work for people is they aren't installed correctly. Make sure you have both a folder called 'draw_angle_dim' and a file called 'draw_angle_dim.rb' in the Plugins folder of SketchUp. The folder contains two image files; interior.png and exterior.png. When you have all those files in place correctly, open SketchUp and look in the tools menu for 'Angular Dimension.' There you have it. There is no toolbar and it doesn't appear in the Plugins menu.

Thanks Dave R; I had just found it hiding on the Tools menu. [is there a way to make it (and other ruby's) appear in a certain order on the Tools menu - like next to the native Dimensions item?]
Would help new users if the usage doc were posted and mentioned how/where to activate it...like this:
Name: draw_angle_dim
Description: Create an angle dimension with arc and text in a new group
Adds item "Angular Dimension" to the SketchUp Tools menu
Usage: - Click 3 points, going around an angle in sequence from any point
on one leg, to vertex, to any point on the other leg (clockwise or
counterclockwise doesn't matter). Be careful where you click -
this tool lets the inference engine assist you but doesn't
force you to click on existing model entities!
- The tool will draw two edges along the sides of the angle,
an arc across the angle, and a text with leader showing the
value of the angle. The two edges make it easy to realign
the group with the original angle if the entity containing it is
subsequently moved or rotated.
- The primitive elements of each dimension are gathered into a Group
named Angular Dimension (<angle>), where <angle> is the measured
angle. If you draw multiple angle dimensions, the <angle> value
will help you identify which is which (unless, of course, you have
several with the same value!).
- Each Angular Dimension drawing is packaged in an operation, so that
undo and redo treat all of the elements as a single step.
- The default radius for the arc is half the distance between
the first pick point and the vertex. The user can override
the radius by typing in the VCB at any time. If a new radius is entered
before the first point is picked for the next angle, the prior
dimension is redrawn at the new radius. The user-selected
radius remains in effect for additional angles until the
user enters a new value or selects a different tool.
- The TAB key toggles between drawing the interior (<180) angle
and drawing the exterior (>180) angle dimension. If you press tab
after an angle dimension is drawn but before picking the first
point of the next angle, the current angle dimension will be
redrawn in the new mode.
- Unlike the built-in "smart" linear dimensions in SketchUp, the
entities drawn by this tool are just graphics; they have no tie
to the original angle and will not follow it or scale if it is
modified. You can open the Group for edit, but it is not likely
you will like the results - it is easier to delete the dimension
Group and do it again.

And of course, thanks, slbaumgartner for a cool tool! ...was just a bit mysterious for me since the location and doc were not posted...

Most plugin writers put that information in their plugins so you can read it after you download it.
As to putting the menu entry in a specific location in a menu, I'm not sure it can be done.

I decide to finally try out this plugin with Sketchup v8 on my Mac. I used the Preferences/Extentions/Install Extension... method after renaming the ZIP file extension to RBZ. The files were installed as stated in a previous post here called "The most common reason that plugins don't work..." with a slight variation that doesn't allow the plugin to work.
The version that I downloaded was for the Mac and was called "draw_angle_dim_Mac". The above extensions installer within Sketchup v8 installed the plugin correctly but one folder level too deep. The installation folder was named the same as the ZIP file "draw_angle_dim_Mac".
You have to move the Ruby script "draw_angle_dim.rb" and the folder "draw_angle_dim" up one level for the plugin to work in Sketchup. Get rid of the folder "draw_angle_dim_Mac".

I don't have a Mac, so I can't check the required paths there (the mac archive was assembled by driven), but what you say is consistent with how it works on a PC.

Actually I think I did the plugin assembly and that seem to be one of my mistake. I seem confused by the zipping thing, and to have it one directory too low seems a recurrent issue.
I'll see if I can repack it and will send it to the author.
Here are the "better packed" files, same one as first post. They will be posted to the first post some time later.
There should be no container folder, but if it appears, it is named "Angle Dim Mac" but the items that should be in the plugin folder are its content, or:- draw_angle_dim.rb
- draw_angle_dim folder

Thanks for that second mac fix... saved my bacon

plugin works fine on my computer (PC)
thank you
i especially like the message at the bottom of the screen, for each point to come; makes it very easy to use

Is it/could it be possible to change the precision of the angular dimension displayed?
It defaults to 0.1 degree, which is fine for most practical purposes. But I'm trying to develop a plugin which will draw regular polyhedra, and while developing it, need high precision displays as I'm checking the maths of the geometry. I'm using a 'unit length' of one million inches, with five decimal digits of precision, for lengths, to check some of the mathematical formulae (Wikipedia seems to have at least one just plain wrong for the tetrahedron)!
-
The precision of the angle is driven by the precision you have set in Model Info>Units. For angular units you have up to 3 places right of the decimal.

Dave, you are absolutely correct. I used SketchUp's built-in formatting for the angle, which obeys whatever the user has set in the model info.

About angle precision... indeed, it uses SU precision, but sometimes even with three decimals, it still shows the ~ symbol. Maybe it should be suppressed if the angle precision goes beyond three decimals, because it is really confusing when you see ~30.000 degrees, for example. It would be somewhat understandable to see ~30.00 when the angle is 30.001 degrees, but as the precision cannot go beyond 3 decimals, there is no point to keep the "~" in that case.
-
You are mistaking the display format for a limit on calculation precision. The units settings in the model info affect how many decimal places SketchUp will display. But it is still perfectly possible to calculate or set a value to more places. For example, if the value is 30.0002 degrees, it will display as ~30.000, telling you that the actual value was rounded based on the display units. This is the same as occurs for all SketchUp units.

Actually I am not mistaking it. I know what you want to say. But I also know that programmatically the "~" can be removed by feeding in a "rounded" value to 3 decimals. So, if SU returns 30.0001 degrees and the plugin will round it to 30.000, then it will NOT display the "~". Of course, this will mean losing the fourth decimal precision... but wait: I can't use the fourth decimal, even if it's there. So, technically there is no lose at all, because SU won't even display the fourth decimal in degrees value.
Is just for best displaying properties... to lead to less confusion.
As an example, I just rotated a guide line with PRECISELY 30 degrees, but this tool shown me ~30 deg. Meaning that SU was not able to make the rotation to 30 degrees sharp (due its implicit precision limitation, which is fine). But again, the value that made for "~" to appear was somewhere far beyond the decimal point (maybe fourth/fifth decimal), which is completely not important. So, if the plugin just rounds-up the value to 3 decimals and dumps everything else, I believe we are in a common sense "territory".
