Illustrator :: How To Calculate Rotation Degree Of Tick Marks
May 21, 2012
I learned out to make the tick marks using copies and rotation. My question now is, how is the rotation calculated so A) I get the correct placement of the tick marks, especially the small ones as there are so many and B) how do I calculate the rotation degree so that I have the proper amount of space at the bottom of the guage/dial?
I know how to get the large tick marks and the small tick marks, if I were placing them evenly around the entire circle, I would know how to do that also - but since I'm placing them around only a portion of the circle (although still evenly) I'm lost. I can only figure out the space by hit and miss calculations and that is taking much too long. I would also need to know how much to rotate the entire thing by in order to get the open space at the bottom as shown.
To summarize: It seems that compounding a path resets the rotation of the gradient to it's original degree of rotation.
Detailed version:
1. Create a shape. 2. Add a gradient fill. Note it's degree of rotation. Let's say it's set at 10°. 3. Now rotate the shape by any means (transform or rotate tool). Note the gradient degree of rotation has shifted the same amount as the shape was rotated (if it was rotated 50°, the gradient will show at 60°). 4. Make it a compound path. 5. Instantly the gradient shifts back to it's original degree of rotation of 10°.
It appears that when rotating a shape with a gradient, the rotation of the gradient is locked to the rotation of the shape. But when making it a compound shape it releases that lock and "remembers" it's original state. But that is only true as soon as you make it a compound path, but if you no go ahead and rotate it just a bit using the cursor (as opposed to selecting transform > rotate), the gradient will switch back to how you would expect it to rotate in the first place...
Workaround would be to make it a compound path before rotating the shape at all.
I need to recreate this dial and I've learned how to create evenly spaced tick marks within a circle, but this is an ellipse. Here, I attempted to draw two ellipse then used the scissors to cut them to size. Then I used the line tool and drew each of the tick marks. Then I adjusted the weights of each tick. This is not a good method because the end ticks are not meeting the ends of the ellipse perfectly, leaving a tiny bit of tick mark outside the ellipse. Here is what I ended up with:
But this is what I need to create: (I only need to create the arched part with tick marks of this dial)
We are introducing a new graph design, but has a problem with not being able to override the tick marks in the category axis in Illustrator CS5. A typical graph (line layout) can have 250 observations, and since we have the tick marks on full width, the graph gets "crowded" with black lines.
In the value axis there is possibilites for overriding the values, but not on the category axis.
Is there any way to script so that the tick marks in the category axis can be reduced/overrided to e.g. 1 in 20?
I have been working on a drawing and out of the blue, when I opened it the other day, all this tick marks where peppered all over the drawing. I discovered they were like point marks from dimension layers that were turned off. If I freeze the layer on top of turning it off, the tick marks do go away. I am running an old version of Autocad, 2007.
Is there a way to adjust the length of the tick marks used in dimension strings? I'd like something other than the supplied Diagonal 1/8" or Diagonal 3/64" options.
Using C3D 2010, I have a drawing that has a horizontal alignment and it is stationed. I see text at every 100 feet and tick every 50 feet. Perfect. I have that drawing x-refed into another drawing. The station ticks take on the properties of the current layer in the drawing they are x-refed into. If I change to layer defpoints, the tick to not plot! Shouldn't the ticks be fixed to a certain layer?
The linear stretch works fine but changing the length affects the position of the tick marks of the polar stretch. If I change the degrees to 0-360 then it's not a problem but I want to restrict to 285-345 deg.
I can't figure out how to move the base angle of the polar stretch with the linear stretch.
All I want to do is rotate one dimension. I want to leave all the others alone.
When I am editing my drawing, I double click on the dimension and get the diag box and unfortunately the rotate dimension command along with the degree box is grayed out.
I am making the hands of a clock with tick marks held in a particular spot with an invisible bounding box. When I export as a png the bounding box disappears and all I have is the tick mark. Maybe a boundindg box isn't the correct description? I have made the hand using the rectangle shape with no fill and no line. The tick mark is contained within this space. But somehow when it is exported using png the invisible containment disappears. I need that to hold my tick mark in place as the hand goes around the clock.
I received a drawing from a client, which has all the features on a coordinate system, But the drawing is rotated for some reason. Even after rotating the drawing the coordinates are the same as it was prior to rotation. I believe there may be some variables that has been changed for this. If a line is drawn A@100<0 it is drawn vertical instead of horizontal and like wise @100<90 is drawn horizontal instead of vertical.
I created an interactive form in InDesign CC and do not like the check marks as they are not visible enough. Can I globally change the check marks to "X" marks?
I drew a 30 degree wedge with rounded short side. Where the long sides meet at the acute angle, a sharp point forms. When I join three of these next to each other, I get a three-pointed overlap at the acute point instead of a smooth 90 degree turn. How do I eliminate the acute points? I am not able to control this using the handles--or I haven't figured it out yet.
How to adjust the degree of curvature on the corners of rounded rectangles in Illy? This can be easily done in PS but I'm not seeing any options for this in Illustrator.
I had a leaflet given to me that I agreed to edit. It was A4 in size and fold in three so the original has six faces. The owner wants to keep the design but reduce it to a single-sheet double sided one third of A4. So I just did the edits and and made the leaflet into three on a page; like this:
My question is how can I put a cut mark in the page. I am guessing that the leaflets can be cut as required. Or is that not a good thing to do and should I put them on a standard compliment slip size?
Open a new document in AI (CS5/CS6), and then draw some arts (rectangles), given an original point (such as 0,0), now I want to all arts in current layer rotate 30 degree around the origin. How to realize it?
Is it not counter intuitive to include the crop marks of an object in the transform dimensions. i.e If I create a box 200x200mm and turn on crop marks the new dimension is 238.1x238.1mm. I can understand a stroke affecting the dimensions of an object but crop marks? I'm not feeling it, I have to remove crop marks from the appearance, change size of the object then re-apply crop marks.
I would like to change the standard length of Illustrator's crop marks. (I need that because I'm exporting colorseparations for silkscreaning. An as crop marks are printed *** well I would like to keep them tiny)
I am doing design exhibitions with interior design. The interior designer sends me an AutoCAD file. The AutoCAD can calculate ratios from the actual sizes, how about the Illustrator? Can it calculate in the same way? For example, draw the line 2 meters from ratio 1:30. Now, we have to compare and calculate length in manual way which is inconvenience for us.
I need to export a Illustrator icon in various different resolutions e.g. 16x16, 64x64, 256x256 etc. I wrote a simple script for this purpose which is calculating the scalefactor out of the image width and the desired resolution.
The scale factor is calculated by this simple formular:
var bounds = item.visibleBounds; var width = bounds[2] - bounds[0]; var scaleFactor = 100.0 * desiredPixelWidth / width;
The resulting images are correct for small images from 16px to 512px but for larger images the resulting images are too big:
desiredWidth resultingWidth1024102520482050409641006000600680008008(the calculated value for width is 512.5)
I have to multiply the scaleFactor with a correctionFactor of ~0.999 to get correct results:
var bounds = item.visibleBounds; var width = bounds[2] - bounds[0]; var scaleFactor = 99.9 * desiredPixelWidth / width;
Why the correctionFactor has to be applied and what the correct value is.
I recently u[graded from a very old Illustrator version to CS6 and I noticed the crop tool is missing. It used to be really easy in the old version to drag the crop tool around the area in question and crop marks would be generated automatically. Then I could save and print just that area only. Now this tool is gone and I am having trouble with finding a way to define the area I want to save or print. When i generate crop marks and then save, all i get is a file with plenty of white around it that also shows the crop marks....
Illustator CS6, my quotation marks are coming up either pointing in the wrong direction, or sitting on the baseline. I've restarted. I've changed the font. Tried pasting from another program.
Working on Adobe CS6..A sign maker has asked me to submit my artwork for different signs (quite a few of them, in different-sizes) as EPS with crop/trim marks.
For instance: The size of this sign is 24"x24" with a .25" bleed. The Artboard shows the right size, and the crop marks show uo as they should. But once I let go of the Artboard, no crop marks show on my screen.
Any crop mark I try adding via the Object ("Create Trim Marks") or Effect menu for crop marks, both cases would create them around the BLEEDS, rather than the REAL ARTBOARD, which, of course, defies the purpose of a crop or trim mark...
I usually submit files for production saved as PDF w/bleeds & crop marks, but this sign maker wants them as EPS.Is there a way around it, other than create those marks manually?
So I am desinging a business card for a company I work for. The company we are sending them off too obviously needs to have the bleed and trims marks. The only thing I can't figure out is how do I make the bleed marks visible to them? When I print the document it shows me the trim marks but since I have a white background, it looks as if there is no border. Should I add a border to the actual Artboard?
