I am trying to set up the bulge for a polyline, in order to set up the bulge currecty I need to know if the polyline was created clockwise or counterclockwise.
View 4 RepliesHow can i test a polyline if its clockwise or counterclockwise? I have a routine that gets the area of polylines then if clockwise,the area is positive and negative if not. But I dont want to get the area just to test if its clockwise or not.

In the below screen shot , I have highlighted a polyline (red marked). So , first I select that polyline and ask to numbering other polylines in couter clockwise.
The result of my requirement should be like below screen shot. how to do that? sample code in VB

I'm using the liquify tool to fit a fake tattoo to a face, and I want to twist part of the tattoo to adjust for perspective. Unfortunately, the twirl tool in liquify is in fact a "Twirl Clockwise" tool- Counter Clockwise doesn't seem to be an option!
View 5 Replies View RelatedWhen using 3D pattern, and specifying a negative angle for counter clockwise, with an angle less than 360 degrees ( eg, 90 degrees ) the pattern will be spread over 360 degrees anyway.
Also, the directions in the application are wrong. negative angles are for counterclockwise, not clockwise.
Workaround: Make all patterns clockwise, and reverse the direction of the axis around which it rotates. This will achieve the desired outcome.
When I open any image, photoshop rotates the image 90 clockwise by itself. All the other programs (even windows imageview) dont do that. Only photoshop does that. I can open the photo in any other application and they are fine, but when I open them in Photoshop CS5, they get rotated.

View 4 Replies View RelatedI have an image, and I want to add some text along a curved path beneath it. Imagine the motto beneath a coat of arms, or a product or company name beneath a logo.
Now, I tried using the text tool to add the text along a path, and I think that I now understand how that works.
Now it turns out that there is a feature missing that I would like to see, which is that text justification should make the text conform to the ends or centre of the path... by this, I mean that if I draw a path and the text is too short to fill the whole of the path, I should be able to centre the text along the path.
The way around this that came to mind is that if the path is a circle then I can place my text starting anywhere, and then rotate that layer to centre the text beneath the image.
So I make a circle selection, and convert the selection to a path... but the path seems to start at the top of the circle (I don't now what you want to call it: 0°, 12 o'clock, top dead centre, North?) and go clockwise... meaning that if I rotate my text to be below the image it will be upside down.
My work-round is to create a temporary layer and draw a circle on it, then use that as a guide to create a path along part of the circle in an anti-clockwise direction.
But I thought that there might be a mechanism for easily swapping the start and end positions of a path,another, better way if placing text below an image,a way of centring text along a path.
Need to create the text as below. (i.e i need to put my project name in Clock Wise what's the way to do it in photoshop ....

How can I stop new text boxes being rotated? When I make a new text box (or start typing artistic text) using the text tool, the box (or artistic text) is rotated 90° clockwise. The tabs also show on the left hand ruler instead of the top one. I have looked at all the options in the Tools menu but there does not seem to a way of changing this. I have attached a CorelDraw file as an example.

View 9 Replies View RelatedI need the features shown in a connected SHP file to display an arrow indicating their direction (i.e. -----> or ----->-----). This seem that it would be important to anyone using Map for municipal engineering (sewers tend to be directional!), drainage (so are culverts!), etc..The difficulty in doing this simple task is just adding to my hatred of Map (especially given the amount of money I've spent on Autodesk products)!

*DIVERSION_LARGE,diversion large ---- >> ---- >> ---- >> ----
A,.5,-.2,["<<",standard,S=.15,r=0,U=0.0,X=-0.1,Y=-.05],-.2
when I draw a polyline, or use it as the linetype in a feature line style, the arrows seem to revrse whenever there is a change in direction any significance. Also, the reverse command and reversefeature command have no effect. Rotating a segment does not change the direction. I know I must be missing something.
In the attached, I have a feature line, and a polyline that the arrows change direction when the feature does.

I want to draw triangle in segment of polyline in segment direction.
I have target segment and center point of it:
Polyline line = ...
LineSegment3d centerSegment = line.GetLineSegmentAt(centerSegmentIndex);
Point3d centerPosition = centerSegment.MidPoint;
I can find direction of this segment:
Vector3d zaDirection = line.GetLineSegmentAt(centerSegmentIndex).Direction;
Next, I create list of points:
List<Point3d> points = new List<Point3d>();
points.Add(centerPosition);
points.Add(centerPosition.Add(new Vector3d(ZASize, +ZASize, 0)));
points.Add(centerPosition.Add(new Vector3d(ZASize, -ZASize, 0)));
And draw it:
wd.Geometry.Polygon(new Point3dCollection(points.ToArray()));
Ok, I have triangle but... it's not in segment direction, it's X-direction.
I try to rotate it:
points.Add(centerPosition.Add(new Vector3d(ZASize, +ZASize, 0)).RotateBy(0, zaDirection, centerPosition));
But it's not the same as I want.
How I can draw triangle by serment direction?
I have created a linetype with the text GAS OPTION in it. The line is continuous with a break around the text. In a straight line the linetype works fine (breaks around the text etc). However, when I use a polyline and spline the line for a curved line the text aligns with the direction of the line at the start, but when the line bends, the text suddenly changes direction and reads in the opposite direction. It looks like AutoCAD is trying to keep the text upright rather than following the direction of the line. When the text changes direction it also changes its insertion point and overlaps the continuous part of the line. I have 2013 AutoCAD.
Here is the string I used for the linetype.
*GAS_Option_LINE,Gas line ----GAS OPTION----GAS OPTION----GAS OPTION----
A,8,-15,["GAS OPTION",STANDARD,S=2.54,U=0.0,X=-2.35,Y=-1.27],-12

Is there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?
View 6 Replies View RelatedI would like to take all the vertices out of a multiple-vertices polyline so that it reduces to just its start and end points, can this be done?
View 4 Replies View RelatedDue to modeling purposes, I need to convert a 3D polyline to a spline. What I have been doing is:
- change polyline fit/smooth to cubic from properties
- convert polyline to spline by typing spline -> object
- method -> fit from properties
You can see the original 3D polyline (green) and the resulting spline (magenta) in the attached drawing.When I zoom in and measure the distance between the two entities at different points along them, at some points the perpendicular distance exceeds 5 millimeters, and I want to ensure the deviation remains under 1 millimeter or even less.
I know I can change the knot parameterization of the spline, and this does work at some locations, but the difference increases at others.Why is there a 5.6 mm difference between the spline fit point and 3D polyline vertex, as measure in the attached drawing?
Now, I can go and manually stretch the fit point to coincide with the vertex. Also, I can add fit points between existing ones to drag the spline closer to the original 3D poly.
However, some of my polys are really long, and it is very time-consuming to do this manually while measuring points along the entities to make sure the distance stays small enough.
how to automate this process? For example a lisp that would maybe take the original vertex points, add say maybe 3 (not too many) new ones between them, and then generate a spline while making sure the deviation is less than the set value of 1mm? I am using AutoCAD 2013.
I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.

I'm currently using Inventor Professional 2012, and have been experiencing problems with virtual memory usage. In past versions of Inventor, the small bar graph counter at the bottom right-hand corner of the screen (Virtual memory counter? Not sure what to call it...) would "re-fresh" after closing a model, drawing, etc. (i.e. Once closing the file, the counter would change from yellow to green, bringing the virtual memory usage back to zero). However, this isn't happening with 2012, and I'm not sure if the problem is the way Inventor was installed onto my workstation, or if it's a problem with the hardware. A temporary solution has been to shut down Inventor when the bar graph gets too far into the yellow range (or red), and then starting up Inventor again.
Specs for my workstation are as follows: Windows 7 (32-bit), processor is Intel(R) Xeon(R) CPU W3503 @ 2.4GHz 2.39GHz, 3GB RAM.
how to dump the counter of parameters of model:
d0, d1, d10, d12
became
d0, d1, d2, d3
Much of our work is structures fabricated from steel plate. One of our practices is to add a note " (SK) " to the description of plates that have a detailed sketch somewhere in the fab drawing set (simple rectangular or circular plates with no additional features do not get these detailed sketches). The actual "detailed sketch" is just a dimensioned drawing view of that plate.
I've been working on automating this process so that Inventor can actually determine for the user whether or not the sketch is required. I have it in certain part templates by default. Other templates add the note automatically through iLogic when certain plate features are selected, or when the model consists of multiple part features.
This leaves one remaining case that the current set of rules can't catch - when the user creates cutouts, notches, etc. by modifying the sketch for the original extrusion. I have determined a method for catching that case, but haven't yet figured out how to program it.
What I want to do is count all of the lines, arcs, and circles in the first model sketch. If that count returns a number other than 4 lines, the note will be added. If any arcs are detected, the note will be added. If any circles are detected with lines also present, the note will be added. There may be other cases that will come up in testing that need to be covered, but I ran into an issue before I got that far. Construction geometry messes up the count - I need a way to exclude it.
Below is the test code I have so far for the counter. what techniques I can use to get construction geometry out of the count. This code doesn't include the provisions for actually adding the note yet - I'm just trying to get the counter working right first. Instead it's just displaying the total count in a message box for test purposes.
oDoc=ThisDoc.Document
oSketch=oDoc.ComponentDefinition.Sketches.Item(1)
LineCount=oSketch.Sketchlines.count
CircleCount=oSketch.SketchCircles.count
ArcCount=oSketch.SketchArcs.count
TotalCount=LineCount+CircleCount+ArcCount
MessageBox.Show("Total Count "&TotalCount, "Title")
Any way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.
