In ClarisDraw one can select Show Object Info which will display the length and angle of a drawn line. How does Intaglio handle this? Shift-click while drawing the line will make it snap to a 45 degree angle but how does one draw, say a 33 degree angle or a 22.5 degree angle?? Thanks.

display the length and angle of a drawn line. a 33 degree angle or a 22.5 degree angle??

Hi Ray, In the Window menu, select “Geometry”, to display the Geometry palette, which will display info for the selected graphic. You can enter values for XY position, height, width, angle etc. and the graphics update as you type.

Thanks Rob, I had displayed Geometry but didn’t click on the little arrow on the right side of the window, which in turn causes the angle to be displayed… oh well… shouldn’t have to do that since it’s a Mac s/w program.

when I try to rotate a square, I get a rectangle : the angle is
that of the diagonal, the shape is not preserved !

it is impossible to set the angle on 90° : I systematically obtain
the value 171° with the song of an alert !

with a drawn line it is not better : there is no rotation, but
deformation, and all angles are not possible (90° is impossible for
example) !

when I try to set 8° in the palette I get /, then 7° gives , 6°
gives / and so on… / / / alternatively ; some time the
resulting effect is… a translation !

the only way to rotate an object with a certain angle is to use the
menu >free rotation< and to observe the obtained angle in the
geometry inspector

I think there is a big bug here, or did I miss something ?

The angle is relative to the bounding box. Imagine a circle around the origin point, the angle measures from the vertical and goes clockwise around to the corner opposite the origin.

To draw a 33° line, put the origin in the bottom left corner and drag a line, then enter 33 in the box, then hold the shift key down and scale to the length required.

Is it possible to have the angles work like they do in Claris Draw? If I want to draw a line at 5 degrees I would draw to the right and up 5 degrees. Directly over head, if you will, would be 90 degrees. If I want to correct the line to 7 degrees I just click on it and move it up. All the while I can be watching the Object Info box for the angles and Lenght. Just like a Mac should work. I’ve tried setting Preferences but it just gets worse.

Is Intaglio written for microsoft computers and ported over to the Mac? I ask that as it seems that if you don’t know hidden tricks getting there is almost impossible.

I’m not familiar with every feature, but I don’t think so, I have just accepted that this is how its done now.

The easiest way to do what you want is draw a line with the shift key and use the “Rotate…” command to rotate the required amount. I have setup a keyboard shortcut for this and it makes it quite fast. If anyone has a better method, I would love to here it?

Ha Ha, that might stir things up. No, I don’t think so.

Thanks for your replies. Have you heard the joke about the guy who asked his wife why she always cut two slices off the ham before she cooked it? If not read on…

Her answer to him was, ‘that’s the way mom did it!’, so he asked his wife’s mother. She said ‘that’s the way mom did it!’. Next he asked the great grand mother. She said ‘because my pan was too short!’.

So, do we really accept things because that’s how its done now or do we get them working correctly? Now, please don’t take that bad, it was not intended that way in any way, shape or form.

It’s just that when I try to use the s/w I feel that I’m running a Windoze program where I have to be typing and clicking with both feet and hands to get anything done.

I still think the way the angles are defined and operate in intaglio
is not coherent and of little utility : its not fair that when I set
a new angle for a line the length of it changes ! the same for a
rectangle : when is it really useful to modifiy its shape on changing
the angle of the diagonal ?

many things are very good and convenient in intaglio, but I find the
angle inspector is abortive (without speaking about the bugs I have
seen (translation etc. on changing an angle) )

There are two common ways to define angles. In mathematics, zero degrees is at 3 o’clock (on a clock face) and a positive angle increases counterclockwise. On a compass, zero degrees is at 12 o’clock and a positive andle increases clockwise.

Intaglio uses the mathematical definition by default but you can control this in the tools pane of the preferences window.

It’s true that the angle field in the geometry inspector is of limited usefulness. It’s mostly useful for individual lines and then only when the origin control (below it) is used to define which part of the line’s bounding box is the line’s origin.

This is mainly the result of performance considerations and the practicalities of complex coordinate transformations.

For example, you could import an image, scale it, rotate it, shear it, flip it and repeat this a couple times by varying amounts. It is now meaningless to try to define a rotation angle of the image. However in some cases (mostly for straight lines) it’s useful to see and adjust an angle. The angle field in the geometry inspector displays the angle between the point specified as the origin (by default the top-left) on the selection’s bounding box and the opposite corner of the bounding box. If you modify this angle the bounding box is scaled to fit the new value. For straight lines this changes the angle, for other objects (rectangles, images, etc.) it changes the proportions.

If you want to rotate an object it’s generally best to use the Rotate command in the Object menu.

Okay, I’ve set the Preferences to mathematical and checked the geometry inspector upper left circle. I then draw a line from clock center to 3 o’clock, one inch long, then move the mouse upwards. As I move the mouse upward the geometry inspector displays the correct angles, ending at 33 degrees. When I let up on the mouse it then displays 327 which is NOT correct since I have the Preferences set to mathematical.

You said “Intaglio uses the mathematical definition by default” so it should still display 33. I know I’m nit picking but I shouldn’t have to have a calculator along side the mouse when I’m trying to draw… now let’s see, what is the mathematical angle of 347, gets old real quick.

Perhaps I need to set some other switch somewhere else.

While you’re drawing the line it knows where the start and end points are so you see the angle you expect.

However once you’ve finished the line it reverts to the standard selection behavior I described above. Since you’ve selected the top-left corner as the origin, you’re seeing the angle from the top-left corner of the line’s bounding box to its bottom-right corner (360 - 33 = 327). In this case the line starts in the bottom-left corner so you’d want to set the origin there to see what you expect.

I’ve thought about adding a special case for paths containing a single line segment that would work like it does when you’re drawing the line, but so far that hasn’t made it into the code.

Please include it into the code. I tried selecting the bottom-left corner and it does give the correct angle when finished but while drawing the angle it displays the 327. So it’s d… if I do and d… if I don’t. They both need to display the 33, durning and after drawing the angle.

Thanks

PS I still like the program but would like this to get fixed.
