...I think the Rectange tool and Rotate tool _SHOULD_ respond similarly to the arrow keys by settign the inferred plane 

Pardon the quote from the other, similar thread: Perhaps the reason the rectangle tool doesn't work with the standard inferences is that it requires two directions rather than just one, so any single inference is not enough. They work for a line (an edge), as it may be defined in one direction, not so a face (a rectangle) which has two dimensions and thus two directions.

For instance, first click you have a point, a corner of the rectangle, second click you have the opposite corner. If the second click is on any axis relative to the first you cannot have a rectangle, only a line or an edge.

right brooke.. i agree with what you're saying

it could sort of work but problems will arise..

i could click the first point to set one corner of the rectangle, then push the up arrow to make it vertical.. but then what? should the 2nd direction now be placed on the green axis? or should it go along the red? or should we be able to push another key at this point to describe the 2nd direction?

i mean realistically, that's how you would have to do it (define first direction with a key press then the 2nd) but that type of complexity isn't in the sketchup dictionary … it'd be pretty confusing, especially for newcomers so i'm assuming the developers just made it default to the ground plane and let the user orbit to determine the orientation (which in reality, isn't even bad.. it takes, what, .2 seconds to orbit to the proper view which will define both axes for you ?)

Re: the Rotate tool "slick ways to control its orientation but it's not very well known" - it's only slick if you have existing geometry to infer to -- you can't enter two precise angles manualy to set the orientation. [to be fair, it is a helpful behavior but would be more useful if you could read and enter the two angles]

hmm.. i don't think i'm following you.. you only need one angle to rotate (in sketchup, we can only rotate around one axis during a rotate operation)

but of course you need to have some geometry in there.. the same goes for the standard use of the rotate tool.. you can't use it unless you have something selected.. (though you can use the protractor in the same way i describe above without anything selected or geometry present in the model)

[Edit] oh wait, i guess you mean which angle to place the rotate tool's protractor at? in which case there are three different angles (up/down - left/right - front/back).. entering those angles manually is going to be a pita even for experienced users.. i don't think i'd ever want to be faced with that type of situation and would much rather prefer using a piece of setup geometry then infer to it..

but i though the thread was about the 3 main axis (getting the protractor to be blue, green, or red) without orbiting the view.. in which case, you already can accomplish that very easily in sketchup without needing to use keystrokes..

Re: gilles;

Oh, yeah, I forgot to mention the Circle tool also does not respond to a forced axis inference via the arrow keys -- and this has caused some frustration.

Not sure what you mean about wanting the Circle tool to behave like the Rotate tool...? Are you talking about being able to select and draw it at a compound angle to being with?...that would just be adding double features into a tool and it's probably less complicated to keep that function separated to the Rotate tool.

-- BrooksL

just a quick example of what you could do if the circle tool behaved like the rotate tool…

try doing this manually:

a random line floating in space (not on any particular axis).. then draw a circle perpendicular to it..

with the rotate tool, you can quickly orient the tool to this way.. with the circle, you can't..

Chris Fullmer's perpendicular_face_tools add circles, rectangles and other shaped faces squarely onto the edges of selected lines, so in effect you have got effective ways to do this, albeit not in the native toolset... http://forums.sketchucation.com/viewtopic.php?p=139064#p139064

Chris Fullmer's perpendicular_face_tools have issues to draw radius under 1" and if edge is connected to a face and it makes group instead of components.

Hi Giles, I did a very poor making this plugin international. It does not work well with metrics AND with comma decimal separators. In the US we use a decimal separator. So 23,12 for us is written 23.12 for example.

The 25.4mm limit appears to be a an inch conversion thing. 25.4mm = 1 inch. I really don't remember if I set this up to work with metrics at all. And I'm so busy I will not be able to fix it anytime soon. If you would like to tweak though, feel free.

Sounds like an 'easy fix'... I'll look at it...

gilles · 21 Apr 2012, 10:24

Thanks in advance TIG.

TIG · 21 Apr 2012, 10:51

I have a fixed version of Chris's tool.
I'll PM it to you and Chris.
He can update his toolset as he sees fit...

that's what i used for the example picture

Uh, my original post referred only to setting/forcing the inferred drawing plane, not the axis for the second reference point. [trying to set bot successively would require another keystroke inbetween there that might make the sequence string too complex to be very worthwhile.

Pressing a single keystroke to quickly set the infered plane perpendicular to the x, y, or z axis would typically be much faster than orbiting to a different view to modify the default ground plane...where you might then not have a good view to acces your next point of inference to end the operation.

...also, orbiting to a different view to reference the desired ground plane and then trying to lock that reference by holding the shift key while you orbit back...that often doesn't work reliably...not to mention it's cumbersome.

Really, it would be very helpful if the arrow keys worked to force an axis or plane reference for all linear and plane tools instead of only the line, move, and tape measure.

[I just realized the arrow keys don't work for the dimension tool either if you want to measure from a point along the x, y, or z axis. ...man, consistent arrow-key axis/plane forcing functionality across all the tools would simply be worlds of convenience to have in the native tool set!]

Yes, kind of -- first, it would be slick to be able to precisely set a piece of geometry at a compound angle (typically not parallel to any axis) in one operation, such as:

select the geometry edge, select the rotate tool, set the reference axis/plane (possibly using the arrow keys that it SHOULD respond to), then enter angle1 comma optional angle2 enter (or click to select last inference).

you could still infer or enter the first angle like normal while the act of pressing the comma "," key signifies it's a compound-angle rotate operation and a second angle will be entered or inferred.

Second and similarly, reading a compound angle measurement with the protractor tool would also be nice.

I hadn't yet run into the need, but yes, that WOULD be convenient, consistent tool behavior - AND, applicable to all plane tools, I think, right?

I see. I guess the same thing goes, even though I understand what you mean. The more literal use of the arrow keys is to define a direction not a plane, so to have them define a plane rather than a direction would involve a stretch of the meaning, perhaps something the SU programmers are not willing to do. A ruby author might, though.

with the rotate tool, you can quickly orient the tool to this way.. with the circle, you can't..

This is exactly the situation I use the perpendicular face tool for daily; when I need a circle (or more often a cylinder) to pass through a plane centered on an exact spot, but not perpendicular to the plane itself. Draw a line where I need the cylinder's access, then create a circle perpendicular to the line and push/pull it through.
