AutoCad :: Ellipse Converted From CAD To CNC Program And Coming Out Jumpy
Apr 10, 2012
I am using AutoCAD 2011. I am taking an ellipse from CAD and converting to DXF and then placing the DXF into a CNC program (Partworks). When the program is run on the CNC router the ellipse is segmented. I have worked with the CNC program and know that the problem is in the CAD or DXF programs. If you can change the size of the segments of an ellipse when it is created or if there is something else I can try?

i'm using Autocad2012 now. when i use paste special in objects and give x or y insertion scale. after i do explode that object the arcs are converted in to ellipses and it come with ellipse grips. before 2012 version it won't happen. what's the change in autocad 2012? is there any variable to change?

I created a program for conversion, which converts layers and dimensions, among other things. My program runs on AutoCad 2012, had no problem with regards to AutoCad 2012. The problem is when I try to print by opening the drawing in AutoCad 2008. The preview is blank. Does some configuration that possibly I changed or I forgot to change so that it is correct?
The drawing (before) prints in AutoCad2008.
The drawing (after) doesn't print in AutoCad 2008.

My aperture / crosshairs seems to have a magnetic attraction to all objects in drawings. Over an empty area, motion is smooth. When crossing over any object(s), be they in Model Space or a Layout, the cursor is attracted to objects. Is this an AutoCAD setting that I'm not aware of, or is this a graphics card / hardware acceleration issue?

when working at this workstation, the crosshair gets very 'Jumpy' and slow as it gets near or cross over a dimension line. is there possibly a setting that is on or off that is causing this. It has nothing to do with the file. It happens on any file on this computer, but if i switch to a different workstation all is well. And this is a much faster workstation than the other. The issue also happens to a much lesser extent when crossing any drawing object. The cursor (crosshairs) will pause slightly. It is a very long pause when near the dim lines though. it is almost impossible to select or snap to an object or line if it is near a dimension line.

When I am in ISO view and chose anything other than wireframe, like "Realistic" panning and zooming are very slow. Even a smaller drawing does not act normal. I use a 3rd party software for modeling ductwork and piping, the drawings work fine on our other machine, so it's not the modeling software. It's also not the drawing file, I have tried other drawings that I had no past issues with but it still bogs down.
I have tried the following:
Updated video driver.
Tried different settings under "Options" "Display" and "3D Performance"
Ran AutoCad repair.
Checked and turned off all snap settings and grid.

I have a sluggish jerky cursor (and it’s not the operator) when you are NOT in a command and while you are creating your selection set in the command. The cursor jumps and reappears @ ~1 sec intervals so you have to anticipate your mouse move to do anything. OH...and it's only happens in model space.
I tried several settings I found on the internet but nothing works. It's only doing it in 3 drawings right now. The latest one was working fine until ~10:00 this morning, then it started in...no issues before this.
It really makes AutoCAD 2011 basically unusable as it takes 5X longer to complete each command!

I am using an ati 6950. (yes i know its not a suggested card) but it runs great other than after 20minutes to an hour worth of use it will freak out when you hover over an object and that object turns to dashed lines. The crosst hair will turn into like 50 diagonal lines and start smearing on the screen. I went in and changed to options from DASH to THICKEN on hover. This has been working for about an hour now.

I've been using the CC version of AE on my MacBook Pro since the evening it came out and all seemed similar to previous AE versions on my home and work Macs, but I just switched to a high-powered Windows workstation and was surprised to see how indexed (not smooth) the CTI was on RAM-Preview. I couldn't care less about UI animation except that it is pretty distracting when watching animations play back aa there is a vertical red line jumping 15 frames at a time. The playback is smooth and previews aren't set to skip frames.
Why is this behavior so different than the OSX version? Can I fix it?

I have Corel VideoStudio Ultimate X6 and am having problems rendering clips in slow motion.
I have recorded at 50p in full HD. In Video Studio I have slowed the clips down to 25%, and when I do a preview in the editor, it looks fantastic. However when I render to a MP4 file it looks terrible. You can see every frame.
How do I render and get at least the same quality as I get in the preview window?
Here is the video I am talking about. [URL]...... through to about 30 seconds to see the jumping.

I just rendered a video slide show that liberally uses pan and scan zooming for every photo and it looks like garbage. It's jumpy and jerky with almost every pan and scan. I used the highest mpeg conversion quality but didn't mess with much else. Is there something I can do to make it not do that? It seems like it gives you the option to use a different mpeg rendering engine if you want...
What a drag. It took me 2 weeks to put this thing together and the final version looks like crap.

I use Canon 60D and normally shoot in mRAW. I am considering a move to DNG conversion so I did some test conversions and was amazed to find that, far from reducing the size of my mRAW files, it increased them by about 60%. I repeated the exercise with RAW files and found that this did reduce the size of the files by over 10%. In fact, i ended up with the crazy situation where the DNG files converted from mRAW were much bigger than those converted from RAW.
Below are some sample sizes based on Medium previews, Embed fast load data - YES, Embed original RAW file - NO, Compatibility Camera Raw 7.1 and later
Before : mRAW 17Mb mRAW 12Mb
After: DNG 28.5Mb DNG 21Mb
Before: RAW 23Mb RAW 22Mb
After: DNG 20Mb DNG 19Mb
If I went for Full Preview, the DNG sizes rose by about 2 Mb
why the mRAW conversion is so inefficient?
I am still not entirely sure whether to adopt DNG but, if i do, it looks like I certainly won't be using mRAW as the source.

I’ve been using very happily been using x2 for a number of years to make a lot of movies from my standard definition camera, I’ve loved the programme, and it has generally been able to do everything I wanted, and made for an enjoyable editing process. However, the camera has finally given up and I’m now going down the HD route, and the old x2 version just keeps crashing with any new clips. So I have recently downloaded the trial version of x5 (5 days of trial left), with the intention of trying it out and then purchasing it.
Unfortunately however I have found it to be jerky and jumpy when editing clips together, particularly when using the overlay tracks, the more overlays the worse it gets. This happens when I want to watch the edit, and while the sound runs ok the video just freezes on a frame then jumps ahead a few seconds and freezes etc etc. Impossible to watch and edit to really.
I am using the smart proxy to get the files to a manageable size, and I can see the separate proxy files in explorer. Smart proxy enabled. I have all the acceleration on that can go on (the ”Enable Hardware Encoder Acceleration” is greyed out so I can’t tick it). When I share/render the movie it comes out just fine, so it’s only with the editing process that is jumpy. I have really enjoyed x2, and could get good results really quickly, and I enjoyed the editing interface and process with Corel VS, but am now thinking I might need to change to a different video editing programme.

when placing a .oam file into indesign then previewing in the content viewer the 'tween' is not so smooth.
Is this a content viewer issue? The animation is simply a 1 second file with content coming in off the stage in a linear movement.
I want to be sure when published to the app store the final result will have a smooth movement.

I am trying to create a cylinder. To accomplish this I am creating two ellipses and two lines. After I try to insert them in the DWG dwaing I can see only the lines. Here is a code sniped so you can see what am i doing.
Double ellipseRadiusRatio = 0.4; Vector3d ellipseMajorAxis = new Vector3d(0.0, 1500.0, 0.0);
Vector3d ellipseLeftCenter = new Vector3d(72541.7, 80198.5, 0.0);
Vector3d ellipseRightCenter = new Vector3d(77145.7, 80173.6, 0.0);
Ellipse leftEllipse = new Ellipse();
[Code] ..........

I'm trying to make a (for lack of a better term) squarish ellipse.
I've tried a few things but they don't work too well, i.e. plines and lofting a rectangle with an ellipse then cutting it two but they just get me arcs that meet at sharp points.
The jpg below is meant to show what I'm trying to do.
I want to take that one quarter of an ellipse at the intersection and stretch/pull it to the midpoint of the line between the corner of the rectangle and the arc. The ellipse is made out of 4 ellipse arcs. I want to stretch just the arc without moving the ends of it at the quadrants.

I've opted for 3D scan of a part, it is Shoe Horn. And the scaned people sent me an .igs format and I requested them to mail me .dwg format to work with ACAD2007. Accordingly they too converted .igs to .dwg, but the converted .dwg file is unable to convert into surface or solid, once if it could be converted in surface or solid only we can do further development.
convert this into surface or solid. make this as surface or solid model, to work further with ACAD 2007.

I have an ellipse with equal radii, I changed it into an arc, but I can't make it fit.
In the attached drawing, there are 3 entities.
1. The original ellipse - red
2. Arc that has the same start angle and end angle as the ellipse - grey
3. Arc that fits the original ellipse - green
Now this is strange, because the ellipse seems to have a different CS for the angles. I had more ellipses in the drawing, but some of them don't have this anomaly.

Recieved a ACAD converted Microstation File for use in an upcoming construction project. Would like to convert all of the existing ellipses to polylines. Have read several threads that lead me to believe redrawing them is about the only real way to do it. Posting here in hopes of a solution. Drawing contains 127 ellipses, and I dont want to redraw all of them!!
Currently on C3D2012.

The path array in 2012 is a very useful addition but I can't crack a solution to creating an array around an elipse (like chairs around a board room table). The only way I've found it to work is to break the elipse and then join up the gap, essentially creating a closed eliptical arc. This gets a result but it seems a very scrappy work-around to something which should simply work.

I would like to arrange equally spaced circles around an ellipse. I understand I can do this with the Divide command, as referenced in a previous thread on a similar subject
[URL].......
But I thought I could also use the Path Array command using an ellipse as the path.
What I get is the replicated objects (small circles) following some totally random path. Strange that this happens only with an ellipse - seems to work OK if the path is a circle or spline.

I use all my knowledge of technical drawing from school many years ago to produce drawings in AutoCAD 2002, but I can't remember how you would define the dimensions of an ellipse in a drawing so that someone could produce it from the plotted output.

My client needs an a3 drawing I drew converted into a PDF so he can print the PDF off to the correct scale.
I created the pdf in autocad 2012 to A3 size and a scale of 1:1. I emailed the PDF to my client who now says that the PDF is not to the correct scale when he prints it, I instructed him to select the 'actual size' option he then said it cut off the drawing at either end of the drawing. He getting very angry now. He wants to be able to open the PDF press print and it to print out to scale.

I created an assembly for a customer of mine who wants a STL of a sword for a possible 3D print situation. I created the part in inches and finished it. When I converted I made sure the document units were set to inches and the export options were as well. However whenever they upload it or check it in other software it is coming up miniscule like it was drawn in mm or cm. I have gone through a number of forums and updated to the latest service pack without issue. Is the issue related to the fact its an assembly being converted to an STL? I have done it before without issue. I have attached the STL in question.
