Resolved

The macbook pro is new to me -- my old laptop was stolen in December 2010. I'm still discovering the differences.

Turns out the new trackpad, aside from being jittery and twitchy (grrr) emulates mouse button 3 -- not 2 for some reason, there is dissatisfied chitchat about this here and there on Apple user groups -- but 3 is emulated with 2 fingers (I will refrain from some obvious jesting).

I can right-click with this builtin mapping, and presto I can now draw coloured and dashed and weighted lines, which is really cool... and it appears I can retroactively style lines drawn with other SU tools such as Arc -- very nice!

My difficulty with 2dtools is now resolved -- and was not a difficulty with 2dtools at all, but with my shallow knowledge of SU.

Don't worry TIG my install is not as BU as you fear. Tool palette is now visible and working.

The revelation I needed was the View->Tool Palettes feature in the main menubar... And yes, I do feel stupid for not noticing it before. So many of my plugins activate their tool palettes by default, that I thought there must be some problem with those that don't -- and if they were not absolutely necessary I just ignored 'em and got on with my drawing

My bad -- as you can tell I'm not a deep Sketchup user, I use it only when I have to get something done; so I don't spend a lot of time exploring all the features (though it's on my list of fun things to do when I someday have the time). Kind of like vi -- most people only know the minimum number of commands necessary to do basic text editing, and never explore the huge toolkit lurking within.

So thx for the pointer to the "obvious" menu item! and yes I do generally understand the packaging of plugins, but it's been 6 mo or so since I fooled with them so it's all a bit rusty. I was grasping at any straw to explain what I thought was broken behaviour.

I fear that the remaining mystery may come down to OSX and mouse buttons (or lack of same).

I still can't get the dashed-line tool to do anything. I can select a line (it becomes bolded); the hint at bottom of screen suggests I then right-click in empty space to get a dialogue box. I am sitting at a macbook pro, with cmd-click mapped to right-click (seems to work in x11 apps anyway, xev confirms). I begin to fear that this mapping may be at the X11 level, though I think in previous releases of OSX it was at the System Preferences level. [a little rootling around...]

Damn. No click modifier mapping for 3btn emu in Leopard System Preferences, at least not obviously visible -- maybe with some googling I can find a way to do it. If not, looks like I will have to buy a trackball or 3btn mouse if I want 2dtools to work.

Sorry for the dimness of the original query. My brain is much more engaged with the stuff I'm building (1100 sf of new sails plus spars to match) than with the s'ware I'm using to draw it. Different headspace

ps Actually I don't use dragndrop much unless the app is chained to the OSX GUI; being an old linux geek I prefer mv, cp, tar, etc. very old-fashioned I know

I hope this is an appropriate thread for my question.

I have never got 2Dtools to pop up a control panel. It correctly modifies the Draw menu, but doesn't offer a toolbar or panel like most other plugins. (I have also not yet figured out how to make any of it work -- have tried to draw dashed lines, for example, but gave up in the end. "Click on empty space" is supposed to do something, according to the prompt at the bottom of the Sketchup window, but I never could get it to do anything.)

How do I go about figuring out why the control panel never pops up at startup? I see a directory full of icons, and I see code that looks like it should build a control panel, so I assume that's what's supposed to happen? I have installed 2Dtools50 with Sketchup 8, and immediately noticed that in 2D#.rb (startup script) there was a case mismatch between the path to 2D#loader.rb:

load '2Dtools/2D#loader.rb'

and the directory 2DTools_50 (cap T, even when the _50 is removed).

I fixed this by renaming the directory 2Dtools to match the startup script. I was hoping that the latest version, with the latest Sketchup, would work (i.e. display a control panel). However it seems about like the old version with Sketchup 7: the Draw menu is modified but there is nary an icon in sight

So I am looking for Sketchup's startup log, where presumably I might find an error message from the attempt to load 2Dtools. It's been quite a while since I fooled around with ruby scripts and Sketchup plugins and so on, and I'm trying to refresh my failing memory

sorry.. i meant plugins folder of course..

if the path is right the icons should show up

as I say I do not speak Ruby, but I used to be extremely literate in Tcl/Tk and the syntax is not completely alien. I have tried various things, even using the full pathname. other .rb scripts are correctly finding their icons w/rel pathname starting at 'plugins', but this one for some reason is not. mysterious! I've looked for some initialisation that might set the default path, etc -- no luck so far. must be a very silly coding error that I can't see because I'm so unfamiliar with Ruby apps.

checked the obvious like protection bits on subdir and images, checked that they really are .pngs, checked that they are not empty files, etc. baffled.

oh well. something to fool with when I've nothing more urgent to do

@cadfather said:

the lines make sense if you have the corresponding folder (toggle_units_icons) in the plugins menu..

plugins menu? or plugins directory (folder)?

that subdir does exist in the plugins directory (as do other subdirs of small images used successfully by other Ruby extensions). can't figure out why the images are not getting associated with the buttons. but hey, the unit switching function works and that's what I needed. I can fool around with the icons later.

Here is the script.
Toolbar to change drawing units quickly.

Hi -- I may not be understanding what this tool does, or how units work in Sketchup; I am frustrated because I can't do what seems to me a simple thing.

I read backwards in this thread and found that others have had some trouble with Leopard (OSX) and this plugin. I grabbed a more recent version edited by Jim Foltz Oct 2009 and installed that.

The Foltz version works except that the icons do not display: this I thought was because the icon paths were all set to CD_ICONS/TWEAK, but I substituted the correct path "toggle_units_icons" and I still get no icons in the toolbar. So I have to memorise the button sequence or wait for the balloon help to pop up but the tool now does exactly what I was hoping for: my ruler can be toggled to work in inches or meters, hooray.

If anyone can tell me why these lines of code

cmd.small_icon = "toggle_units_icons/tudec16.png"
cmd.large_icon = "toggle_units_icons/tudec24.png"

do not correctly association the png files with the button, I'd like to know (I don't speak Ruby obviously). meanwhile I'll happily use the version with anonymous blank buttons -- project no longer stalled!

Hi -- I may not be understanding what this tool does, or how units work in Sketchup; I am frustrated because I can't do what seems to me a simple thing.

Here is the deal. I am working on a model in non-metric units (feet and inches). But I have paper sketches from a colleague in Norway who has annotated his drawings in decimal meters. I'd like to reproduce his hand drawing directly into my model by copying it exactly, so I'd like to work on a set of components in meters or mm. To my surprise I could find nothing in Preferences for toggling from metric to inch and back. So I thought that Toggle Units plugin might enable me to switch the whole model from inch to mm or cm.

I installed it. But it seems to toggle units only between different representations of inches (the first 4 buttons); the other buttons (mm, cm, mt) are grayed out and inactive. I really want to toggle between metric and inch -- is there no way to do this? it seems such an obvious thing to want to do argh. would rather not have to use a unit converter and manually convert all the dims on my colleague's drawing!

btw I am aware that I can draw in any units I like, i.e. enter dimensions in notation like "3.0m". what I cannot do is use the Ruler tool to verify those dimensions after drawing, because the ruler is apparently hard-wired to inch units. if I could just toggle the Ruler between inch and metric that would be great!

any ideas would be gratefully received as this has got me bogged down right at the start of the project.

What you have model so far looks pretty well thought out... except... I suggest you make all of the elements into groups (or components if they might be repeated). [...]

O my, I wish I had started out doing this (making each major new area of the model a layer). Trying to select stuff after the fact, group it, and layer it, is pretty tedious and delicate work. However I have done some of this and it is useful to be able to turn on and off entire design elements like Roof, Walls. Thanks for the thought-provoking tip!

that's z-fighting

you have two faces on top of each other.. you'll have to delete one of the faces if possible. (or get them off of the same plane via some design change)

[edit].. it would probably help if you upload the skp.. two reasons -- one, people could find the problem more easily and two, they could show you how to fix/prevent it more easily

aha. I don't know how duplication happened exactly, but it doesn't surprise me all that much. I'm working "in tight spaces" and having difficulty controlling the over-eager inferencing feature

As a newbie to CAD I'm discovering all kinds of technique issues. My approach -- which may have been stupid -- was as follows: first, draw a handful of necessary components for my interior sketch (such as a wood stove, double sink, and propane cooktop with dimensions taken from real life). Then I worked intuitively from larger to smaller structure, taking the outside dimensions of the cabin followed by the inside dimensions, roughing in bulkheads (walls) and doorways. Then I tried to draw the interior joinery (countertops and so on) and place the prefabricated components. Here's where it started to get tricky, as I was working inside the structure with weird sightlines and too many vectors to which SU kept trying to snap lines. It got harder and harder to see what I was doing as the visual field got crowded.

I can hide surfaces, of course; but sometimes I need to be able to see some structure for alignment and orientation, yet it's in the way wrt mouse-picking. I had moments of hair-tearing frustration with objects popping around into different perspective lines on the tiniest mouse movements or objects refusing to move on the axis I was trying to relocate them on, but arbitrarily (it seemed to me) insisting on a different axis. any tips on "how to work effectively inside a Sketchup architectural space?

I'll attach the skp file in case anyone wants to comment. I am sure Enlightened Masters like Gaieus will find it hideously amateurish and sloppy but in this case it really is a sketch, with approximate dimensions for a reality check. I'm not planning to take a cut-list off it! just to get a feel for what's possible... nevertheless I'd be interested to learn how to do things smarter and easier, and especially how to reduce the mess, orphan surfaces, weird little gaps, etc.

The most difficult Sketchup activities, imho, are selection and relocation. Constructing shapes is dead easy (brilliant interface and metaphor imho), and measuring is delightfully intuitive with Tape Measure. Construction lines are dandy -- except for the darned x or + signs at each end, which are hard to select and erase (my models usually end up dotted with orphan +'s like fruit flies). The fancy special effects (plugins) are like a big box of candy all tasty and so easy to use.

But the really challenging task is the basic one of properly selecting and repositioning elements; sometimes I feel like I'm fooling with a Rubik's Cube, trying to find just the right POV and order of operations to slide a piece into its correct place. Even with X-ray option and surface hiding, it can be tricky. One of the disconcerting things to this n00b is the way that surfaces and shapes become melded with the larger model as they snap to its edges or surfaces; several times I've wanted to resize a "plane" such as a wall, only to find the whole model distorting because the plane is now glued to the rest of the model along one or more edges. I sometimes wish there were a way to divorce a selected chunk of geometry from the model, fool with it, and then glue it back on.... but there are other ways to accomplish such modifications and I'm learning them slowly

Rough sketch of new galley layout

I can't think of a better way to describe this.

When a face has been painted with a texture, sometimes (I am not sure when or why) if I draw another line across that face, the texture goes all "shimmering" -- broken up by white streaks which change shape and location as the camera orbits. photo attached... is this an OSX bug, or a SketchUp bug, or a known symptom of something that users should not do?
