AutoCAD 2013 :: Convert Ellipse Into Spline Or Polyline?
May 3, 2012
Our customer send us drawing with ellipse into.With Autocad 2008 I bought a plug-in call SplineConvert that did the job perfectly but not compatible with 2013.
Is there any plugin that could replace that tool ?
Is there any standard ACAD command that could easily do this Job ?
I need a way to make 2 or 3 times per week this converting on all ellipses of large and detail 2D drawings so no time to offset in and out all those .
I try also DXFOUT in R12 but all the spline are being converted into 3d polyline making a huge files that froze my PC.
I also try FLATTEN but did not see how it work , the ellipse stay an ellipse.
Can I convert a section of an ellipse outline to polyline so that I can see it's length from Properties? And why Properties does not show the length of a spline?
I would like to convert a spline to a polyline for the sole purpose of finding the area. Is there a way to do this or is there another way to find the area of a spline? Typing list does not give me the area.
Due 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.
The attached profile is a section from a solid. I would like to create a closed profile in order to extrude the shape into a solid. The polyline command and splinedit don't seem to do the trick.
Im using autocad lt 2004. My plotter does not recognize splines, and I would like to convert them to a polyline. How to do this, been trying to do if for a few days now but to no good.
when I highlight the spline it will not give me a option to turn the spline into a pline.
I am trying to LOFT multiple ellipse shapes along a spline path to create a door handle. But as soon as I choose 1 section, MAX creates the shape. I cannot figure out how to create the shape with multiple cross sections. I have attached a screen shot and a pic of the door handle I want to create.
I am a student and I am trying to transform a spline into a polyline with the AutoCAD 2009 that with have at Uni for the CNC machine but "pedit" doesn't work.
I need to draw a polyline (or spline) in the XY-plane, followed by a vertical segment before continuing in the XY-plane again. The challenge is working out the vertical part while still in the top view. There's no way to change its elevation on the fly that I know of.
The surveyor's CAD file includes a boundary line that is mostly curves. It's drawn as a spline. I'm trying to create a PROPERTY LINE in Revit. I've converted the spline to a polyline in CAD. In Revit, PROPERTY LINE sketch mode, I can hghlight the polyline but can't select what I've highlights. Only one of the polylines gets selected. So I have to try to select them all one at a time. converting a spline to polyline in CAD for use in REVIT?
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.
Okay so is there anyway to enter the whole equation of an ellipse into autocad and it will map it? ex x^2/a^2+y^2/b^2+z^2/c^2=1 with different values for x y z a b c. I want to generate different ellipses and then loft them together?I just want one the starts with the basics and goes all the way to the move advance stuff.
I have created a big spline. When I tried to "Convert to poly", it doesn't work. Usually, as result, the spline appears with a filled. In my case, the spline disappears. I thought it might be because the spline is not closed, but it is correct.
I want to convert a line (Autodesk.AutoCAD.DatabaseServices.Line) to a polyline (Autodesk.AutoCAD.DatabaseServices.Polyline).
Currently I get all the properties from the line, create a new polyline with it and delete the line. I fear data may get lost this way. What is the best way to convert a line to a polyline?
// Line properties:// Color.// Layer.// Linetype.// Linetype scale.// Plot style.// Lineweight.// Hyperlink.// Thickness.// Material.// Start X.// Start Y.// Start Z.// End X.// End Y.// End Z.// Start point.// End point.
I've MAP 3D 2013 64 bit (French version) with SP1.
When I launch command to "Convert polyline to polygon" (_MapPolylineToPolygon), I've message on command line "Select objetcs", I can convert to polygon =>OK
If I launched this command a second time, I've no possibility to select object, I come back to command line.I quit MAP, then launch MAP, and I can use this command only 1 time.
how a drawing was exported from another program. My problem is: the PEDIT command won't give me the option to convert a line "I" add to a pline.
PEDITACCEPT: 0 or 1, problem remains
It is a drawing from an house designer, I am adding structural members and notes over the drawing. I could xref, but I need to move/erase some of their notes as well. It becomes cumbersome to switch to the source dwg, edit & save, move to current dwg and refresh, to have the note where needed.
This is a pretty strange to me drawing file. It seems that a bunch of system variables are altered and hopefully it doesn't migrate over to files originating from my machine.
