[Plugin] Angular Dimension

[slbaumgartner]

This tool is an extensive rewrite and enhancement of the idea from Didier Bur's dim_angle.rb. It draws angular dimensions onto a SketchUp model. Changes from Bur's original include:
- user input of desired radius of angle arc, modifiable after drawing until next angle is started or another tool is selected
- user selection of inside (<180) or outside (>180) angle, with cursor indication of mode, modifiable after drawing until next angle is started or another tool is selected
- packaging of drawn elements into a named Group
- undo capability
- clockwise vs counterclockwise selection order does not matter

To install, download and unzip the attached file in your Plugins directory.

[edit] The original version works for Windows but has issues on a Mac. Michaelv and Driven worked on it to make it compatible. If you have a Mac, you should download the second version attached.

[another edit] After finally getting my hands on a Mac, I discovered that the reason for all the struggling with the cursors is that on the Mac, SketchUp is not happy with the color profile info that my Windows pixel editor put into the png files. I opened them in an editor on the Mac, touched them and saved, and then they work. This is especially puzzling since other apps on the Mac are quite happy with these files, just not SketchUp! Anyway, those using Macs should load the final version that Michaelv attached to the last post in this thread.

hi,

it's holding on to the 'Orbit' or 'Pan' cursor if I use either between angles.

it's own cursor comes back and functions, but is hidden behind the hand.

I'm on a mac

otherwise it appears to be working, well done. no error messages...

Hmmm...it doesn't do that on my PC. I don't have a Mac to test on. Maybe someone in the group who has a Mac can help sort this out?

Hi,
I just read your script and your cursors use all UPPERCASE which was actually failing gracefully, ie. '@cursor' not defined, but the tool still works.

I had a look at your cursor images and see that they had never appeared. I'm getting the 'snap to' squares...

I'll downcase the cursor names and see if that works, but I suspect 'Tab' key will be an issue on mac.

That seems unlikely...all uppercase is pretty typical convention for constants in Ruby, and should have nothing to do with Mac vs PC. If you are finding @cursor not defined, that seems more likely a problem with the path to the icon files. Are they installed in Plugins/draw_dim_angle?

Try this: open the Ruby Console window and type DrawAngleDimTool::IN_ICON into the input space. The output space should then display the path for interior.png. If the path is mangled or isn't where you installed the png image, that is the problem. You can also type DrawAngleDimTool::IN_CURSOR and you should get a number back, probably somewhere a bit more than 50000. If that doesn't work, SketchUp failed to load the image file.

If you look at onKeyDown, there is a code snippet to print the keycode you get on the Mac. Please let me know what value you get and I'll see if I can code in a trap for PC vs Mac.

Based on this, it looks like maybe it would work if you rename onKeyDown to onKeyUp, as it looks like the up is reported for TAB as key 9. Could you try that and let me know if it works?

Thanks

The responses to IN_CURSOR and OUT_CURSOR say that the cursors were created, though I'm not sure that means they found the image files. The response of nil to @cursor indicates nothing, since @cursor is an instance variable not a global. So, the problem still seems to be that the keypress is not toggling the mode to outside. Please try the attached, which looks for the up key event (will not trigger until tab key is released) and let me know if it works.

[driven]

Hi,

the path is fine, I just didn't have that in the log I posted, so it's included here.

Code: Select all

> load('/Library/Application Support/Google SketchUp 8/SketchUp/plugins/draw_angle_dim.rb')
true
> DrawAngleDimTool::IN_ICON
/Library/Application Support/Google SketchUp 8/SketchUp/plugins/draw_angle_dim/interior.png
> puts "cursor File Exists? " + File.exists?(DrawAngleDimTool::IN_ICON).to_s
cursor File Exists? true
nil

with the latest file the Dim Angle itself is switching, but still no custom cursors.

because Tab also toggels focus on the Inputbox, I changed that to use VK_ALT || 524288
which is more in line with the standard tools and avoids the focus toggling issue.

so the tool functions fully now, just no curors...
john

[slbaumgartner]

I have to admit that I am lost and without a Mac I don't know what else to suggest...sorry! If anyone else can figure this out, I'd love to hear.

[Michaelv]

Same as John,

Substituted VK_ALT on line 350 for == 9 so that option key toggles.
I have no cursor, but I'm working on it.
Also I will include a text to outline what key toggles.

Otherwise functions great.

Thanks

[slbaumgartner]

The mode key seems to be a no-win situation! Maybe I should think of a different mechanism to change the mode. On a PC the TAB key is unassigned, but the VK_ALT activates the File menu! On a Mac, the TAB key is preassigned, but not VK_ALT! By the way, when I try to use VK_ALT on the PC, the cursor alternately disappears and reappears as I press the key! Something similar may be what is happening on the Mac.

[driven]

@Michaelv,

the key generator is on the forum, but if you want a slightly updated version, that's easy to add to... I'll PM it to you.

BTW. if you use either one VK_ALT or 524288 it toggles from the Alt key, but if you use the ruby either/or VK_ALT || 524288 then not only does ALT toggle, so does RETURN!! which shows as 13 when I ran the test. SU key mapping needs checking.

as for the icons, they work on toolbars, so the file and path are ok (but I made new ones as well), their just not being seen by ruby,

I'm having a similar problem in another script where only the 'before' half an if not block being seen. Is this a Ruby 1.8.5 (mac SU ruby) issue?

john

[driven]

the VK_ALT activates the File menu!

Have you set that as a system shortcut?... do you have assistive devices activated?

Does Alt open the File Menu when you use 'move' or 'scale' tools?

are your Plugins still all on? [I turn mine off to test new rubies on there own]

john

EDIT: did you try 524288 that work here as well.

Alt key opening a menu is a standard PC shortcut - I didn't do anything special, no assistive devices. Interestingly, ALT seems to affect just about every tool *except* move, on which it does nothing that I can see! And with the Paint Bucket it displays a dropper icon to let you select a Material to match so long as you hold the ALT key depressed. Goes back to the paint bucket when released. You gotta love consistency and portability!

I didn't turn off other plugins, but on my PC the tool functions ok so I didn't think that would add anything to this mix.

Regarding the cursors, is there any chance that the problem is with png files? Do you have other tools with custom cursors from png files that work?

All of SU's cursors are png's so that's not the problem.

I want them to work now because I made new ones.... damm
didn't really need the cursor before.

I'm on a PC but trying to help get this tool to work for people with Macs...
On a PC, the CTRL key toggles the move tool to copy, not ALT!
Re the cursors, do you have any examples of a tool with custom cursors that do work? I'd like to look at the Ruby to see what it does. I thought I was following the documented code...

[driven]

some progress...

if I use either of these changes, I get the inside cursor and a one-off toggle.

Code: Select all

  def onKeyDown(key, rpt, flags, view)
      if key ==  VK_ALT
    #  @inside=nil         # uncomment this with the original order below i.e. true = false
      !@inside = @inside     # or switch it to false = true     orig.  @inside = !@inside
       if @inside
        @cursor = IN_CURSOR
        else
        @cursor = OUT_CURSOR
      end

not sure what to look for next... john

[driven]

Chris Fulmars 'shapebender.rb' come easily to mind, in the Plugin section here.

I got one step more with trying versions of this, I can switch from inside to out logos once...

could you split this into 2 separate actions, holding down the Alt is common for SU tools, as apposed to toggling...

Code: Select all

      if key ==  VK_ALT
       @inside = false && @cursor = OUT_CURSOR
        else
        if key ==  !VK_ALT
         @inside = true
         @cursor = IN_CURSOR
      end

[driven]

here's some I made earlier.

exterior.png

so we have to get them working.... john

[driven]

got it...... could be tidier but it's working

Code: Select all

  def onKeyDown(key, rpt, flags, view)
      if key ==  VK_ALT
       @inside = false
       @cursor = nil
       @cursor = OUT_CURSOR
     # end
     
      # redraw in new mode if appropriate
      if @drawn
        # undo the previous operation before redrawing
        # this avoids buildup of unneeded operations on
        # the undo stack       
        Sketchup.undo if @state==0
        draw_angle_dim
        else
        # make sure the cursor change takes effect immediately
        # without this it doesn't change until the user moves
        # the mouse
        UI.set_cursor(@cursor)
      end
    end
  end
 
def onKeyUp(key, rpt, flags, view)
      if key ==  VK_ALT
       @inside = true;
       @cursor = nil
       @cursor = IN_CURSOR
       end
end

How strange! The key feature seems to be the assignment of nil before assignment of the new cursor. I can't imagine why that would be necessary, but if it works...

This is something I was looking at today for the other ruby issue, and I just thought I'd play around with the assumption that
having Booleans and conditionals mixed together Can cause issues like false = false ==> true

I thought I was following the documented code...

hi Steve
I missed this earlier, but that could explain the problem... there are so many gotcha's...

one thing that happens now is the to icon switches on button up but the @inside changes on next mouse click, could a conditional delay the icon?

you should probably move 'cursor bits' of this to the developers forum, tidier for plugin browsers and you might get some answers from people who know what their doing....

I just try and make other peoples scripts work on mac's, and write a few applescript/shell/su type helpers.. and bets test for anyone really...

[Michaelv]

Well at this point in regard to the mod keys for scripts, I'm figuring that the easiest way is to have a Mac and a PC version of the script. Not only it's the easiest from the point of view of scripting, but it allows to use different modifiers, which is more within the usual practice of each machine.

I have a version ready for you, including text but there is still the cursor issue.

I worked on the cursor issue yesterday and it's a tough nut. I changed the cursor scripting to make it similar to the API example and to another script I have (in progress) where it works. And it still doesn't work . There is no difference between the two, yet it doesn't work in this script, and there is still the orbit and pan cursor remanence issue. So something else is going on, which I have to figure out. Maybe today.

Sent you a PM

[Michaelv]

All Right, done.

So here is my final script for MAC:
Thanks John I used your mod (and changed it a bit, no more onkeyup), cursor works great now. And option toggles everything, text display and cursor, try it!

[Michaelv]

OK the plot thickens.

I tried the original icons for the cursor, and it doesn't work. Only John's Icons work, now that's weird, they have the exact same name and extension and location.

Also when the option key is pressed the icon only switches when the mouse moves on my version. I'll see what can be done.

EDIT: Only when I toggle as the dimension is already drawn, if I toggle while it is being drown, icon switches instantly. I thought I didn't dream it before.
