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?
View 3 RepliesI 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?

When I try in 2011 it does. Try in 2012 with attachment, no luck
I just upgraded to LR4. I have a number of images that I converted to black and white using Silver Efex pro directly from Lightroom 3. I also have scans of images from black and white negatives in my catalog. When updating these images from process 2010 to process 2012 in LR4 each image becomes ever so slightly warmer (dirtier) on the screen. I noticed this because when updating the process I checked the review changes via before/after box. Some of the images where tweaked a bit in lightroom 3, others not. Strange thing is that when I run the cursor over the images the RGB values in the histogram are exactly the same in the before and after images.
I would have to say the before looks cleaner and more neutral. I don't mind using process 2010 for previously worked on images; however, it does seem to defeat the purpose of upgrading.
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 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();

I need to make an ellipse that's cut in half, and I have no prior 3D experience that's useful to create this shape.
View 9 Replies View RelatedI'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.

View 3 Replies View RelatedI'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.
I want to create a new order. when using the order,It will create a ellipse and a DTEXT .I mean the ellipse and the DTEXT are a whole. when move the ellipse the DTEXT will alse move.However, users can edit the DTEXT.

View 7 Replies View RelatedThe 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.
View 3 Replies View RelatedI 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.

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 have a 2d dxf file (attached) that i need to somehow convert into a 3d file with a material thickness of .75 inches (a piece of wood) so that the cnc can cut it it keeps giving me an error of no thickness in the machine.
View 4 Replies View RelatedI 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.

I have a database of the 50 stars closest to the Sun. I wrote a program that translates Right Ascension and Declination into X,Y,Z coordinates on the "normal" UCS view.
I created all stars in 3D, distances to scale (1m = 1Ly), stars as spheres 0.1Ly radius (so they are visible !) Now, I need to draw the elliptic trajectory of a rogue "planet", starting near Lacaille8760 (6.456, 7.664, -8.076), passing near the EZAquarii, A, B & C, located at 3.557, 10.268, -2.973, to get a slingshot that will launch the planetoids towards the Sun (0,0,0). The elliptic trajectory should be a 3d "tube" a few pixels dia.
Problem:
How to set the screen coordinates to the plane formed by the 3 points above, so the ellipse can be drawn on a plane ? I changed the UCS to 3 points, and the screen shows the three stars on the same plane, but when drawing the ellipse, it is to the original UCS...
I'll make the ACAD files available for download at [URL]...... "TECH" tab. Once created, the drawing is used in R14 format to be imported in 3DSMax8 to get easier views and animation.
I'm having difficulty with a sheet metal part creating a flat pattern for it. The shape is an ellipse with the dimensions shown in the second picture. When I attempt to create a flat pattern it just shows the side of the part. The sheet metal defaults are correct for the part and it was ripped to created a base point for the pattern. I need to create a DXF for manufacture. I would just use the flat pattern it gives me and mirror it twice to create a pattern but it doesn't factor in the radius of the part. How to create a correct flat pattern for this item?

I know that stretch will not affect major or minor radius of an ellipse in dynamic block.
What I would like to be able to do is use properties of an ellipse and some kind of parameter to be able to affect values in properties.
I know how to get ellipse radii data out of a block, but I simply cannot find a way to get them back in...
Is there a way to link field data back to block...?
Is this supported by Autodesk, and will installing both products create any issues?

I want to be able to select (using the File Open dialog box) a "Step" file that I have downloaded from my supplier, then convert it to an IPT file (NOT AN ASSEMBLY!!!), automatically.
I have a configuration file (.xlsx) where I have put in Client, project number and a date (as a custom iproperty). These cells are linked to the iProperties in the IDWs. The project number and client works well, however im struggling with the date. The date is written dd.mm.yyyy in excel, and Date1 is set to date type.
Date1 = GoExcel.CellValue(ThisDoc.Path & "Project configuration.xlsx", "Sheet1", "D4")
When I run the rule Date1 changes type from Date to Number, and inserts a random number.
By inserting this
Date1 = DateString()
The date is converted to mm-dd-yyyy, but with wrong dates. If I write 15.10.2013 in Excel it will write the date as 08-01-2013. How to get it written lik 15.10.2013?
The arcs in the object i have drawn gets converted to lines when i mirror the object.
