2D drafting ruby
-
Of course, such a script wouldn't truly be 2D drafting - just a quick way to change several camera settings (i.e. turn off perspective and switch to an ortho view) and modify the mouse behavior. You would still only see whatever is on top/front and draw on that surface. A true 2D plugin would be a headache to write and I don't think would add much; there are plenty of 2D programs out there already.

why settle for that... if they're gonna write something... allow us to select a plane such a the section and only work in it...
-
past the scope of what I was looking at, but that could certainly be useful at times!

Okay, I hear you.
I can't promise it will happen quickly, but it's on my radar now. -
Rick you rock man...

What about this approach for a 2d drafting ruby - disabling an axis, as opposed to changing perspectives and cameras etc ...
...
A ruby (eg connected to command buttons) that only allows drafting in 2 axes (ie DISABLES one axis).That way, you could draw in 2d - safe in the knowledge that your geometry wouldn't be wandering off in the blue (z) direction for instance.
The buttons would allow you to draw in ANY 2 axes but not a third - would be VERY useful.
Even drawing in this proposed 2d drawing mode I can still see that it would be VERY useful to have the ability to be able to have a perspective view on an object eg drawing detail on the gable end of a building etc
.....
You could also use this feature then for drawing in plan mode with perspective off if required - leaving it up to the user to change cameras, perspectives etc as needed.
...
It would be a ruby that could lock both the red and green axes (for example) - AT THE SAME TIME.
...

Thanks for all the help and suggestions, some great ideas coming out. Howard - sounds like that might work, but what if you happen to want a non-axial plane such as a gable wing that comes off the rest of the building at an angle?
I asked this over at the Google forum and have got some good suggestions about how to get started. From some of the Smustard guys actually, so that worked out well. Here's the link if anyone's interesting in joining/pursuing this idea over there.
sorry the link doesn't seem to be parsing correctly; what'd I do wrong?

I corrected it for you. All you need to do is paste the link in. I think because it was so long when you put the brackets on it did not want to behave.

Link works now - thanks!

great idea.... for the locking axis' as for how to make a gable line in that mode, simply draw a straight flat line and rotate it up to the angle... may have to put it in a group.

When I was doing animation back in the day on my Amiga A4000 (yes, vintage!), the 3D app I was using was called Imagine. It had 2D views that would not allow the user to orbit, and then it had an Iso view that would remember your camera position, lens and zoom level.
Would this be of interest as a feature request for future versions of SketchUp? We already have the Views toolbar, but perhaps we can enhance this so that the 2D views can be locked so that you can't orbit, and the iso view remembers your last camera position.
I can pass that along.
Sound good?

sounds good... however the axis lock of the line usage really interests me... there are many times when I need to work in a certain plane and would love to lock it down...
-
I'd like to request that as a feature, sure! I don't think that the standard Views buttons would have to create a lock - that's the point of switching the mouse button to pan instead of orbit when the 2D lock is on (although that's just my preference - do most people primarily use the wheel to navigate?). You could still switch views or orbit manually; align camera to face would also work. The 2D button could sit on the Views bar though; I would think it could indicate on/off like the X-plane button. Also in the menus it should have a check mark, like Perspective.
I'm not even sure you'd need to go back to whatever view/camera was active before 2D was enabled; how often would you really need to? If it was a common enough view you'd probably have a scene for it. That raises another point though - if you were in 2D view and clicked a scene that had perspective, should 2D stay on?
One more thought; perhaps "2D Mode" could show in the upper left corner, similar to "Two-point perspective" and "Top" or "Front" when those are active.

This idea is getting me excited.
Could it include a smart-wall function to draw interior and exterior lines in one step? The thickness would be user-defined, of course, with an option for defining the height. It also could be integrated with the door and windowizer scripts to automatically place components that would become 3D when viewed in perspective mode. Perhaps this is getting ahead of things, but it does not seem like it would be too difficult to integrate these features, especially since some of the functionality is already developed.I think it would be really great to have a better integration with dimensioning. In 2D, dimensioning would seem to be much more managable to script. There was a thread about auto-dimensioning somewhere, this would be the perfect opportunity to integrate this kind of feature.
And then there would be potential integration with the housebuilder features! I'd better stop...
-
I think the housebuilder plugin provides most of the 2D/3D connections you suggest; you can draw 3D walls glued onto the 2D plane and they would still appear 2D in 2D Mode since perspective would be off. Section planes can also clip things down to only the 'plan' level, keeping all the 3D stuff out of the way.
As for auto dimensioning, that does have a pretty good thread going already; I think the two could work together, but shouldn't be integrated into the same function/tool; you may not always want both.
