We imported a DGN file and all the arcs, when you click on them have a grayed out circle completing the arc. When I list them, the come up as ellipses. I need to join these arc/ellipses to adjacent polylines.
View 9 RepliesI have two adjacent circles. I created two tangent lines between them on opposite sides. I want to connect the lines to the circles. So - I make the circle into a pie, and with the node editing tool, drag the nodes around until I see the little info text go from edge to "node" where it snaps on the nope of the line.
Before I start this, the lines are perfectly tangent. When complete, the lines are no longer tangent and the circle is shifted upwards, and is moved off the perfect tangent by different amount for each line. I can see a difference at 3200% and 11000% zoom at 0.5 point lines.
This occurs if I rotate the circle, or make the circle into an arc also.
It seems that when the circle is drawn, the center point about which its rotated, and from where the arcs/pies are drawn is not exactly center. This is happening when I manually rotate it. It I rotate it giving it a specific degree in the properties bar across the top, it rotates fine. For instance, repeating this again, the arcs of the circle is below one line, and above the other live by a lesser degree.
I have a large amount of "ellipses" in a Civil 3D 2013 drawing that were created as "circles" in Cyclone 8.03 (the laser scanning software from Leica-Geosystems). I need to work with circles so I can label the diameter of each in my drawing. Is there a way to automatically convert these ellipses, that have the same exact minor and major axis, into circles? Other wise I will have to reapeat the work in Civil 3D using the same point cloud!

When you import a Layout, it brings with it all attached images from the source drawings even if they are in Model Space.
When the attached shape file (change soilmu_a_a.txt to .shp) is imported using MAPIMPORT the data aligns with other imported georeferenced raster imagery (said imagery was imported using the MAPIINSERT command). If the same shape file is imported using the data connect tool it shows up in a much different location (see word document).
The drawing coordinate system code is "UTM83-18F" and the data was downloaded from the Web Soil Survey's data download with the identical coordinate system (see attached readme.txt).
I prefer to use the data connect option when importing this type of shape file because I can label them all using a theme and use stylize the data for visualization/presentation.
As an aside, I have found that data connect does not automatically transform data coordinate systems to match your drawing coordinate system as advertised. I've used the edit coordinate system to no avail; however, again when the file is imported using MAPIMPORT and saved as a drawing (with native data coordinate system) and then that drawing is queried from a drawing in a different coordinate system it seems to transform the coordinate system just fine. Is this a problem with data connect?
I have some polylines that mark the edge of roadway and around the curves there are arcs in the linework. How do I turn the polyline with arcs in it into a polyline with vertices, say, every .5' or so along the curve and turn the curve into a polyline? I tried the pedit and using decurve but it doesn't work well.

I have many segmented polylines that I need to turn into arcs. See the attached image for the method I use to create an arc from a single polyline. I need to do this to thousands of polylines. Does some other method that can do many polylines at once?
View 5 Replies View RelatedI am trying to write a *simple* DXF export procedure in a Delphi program.
I can generate PolyLines, Text and Circles OK but am having real problems with Ellipses. No matter what I put for the posn & axis, I just get a tiny circle drawn at 0,0. Oddly one DXF viewer (online) does show the ellipse correctly but 3 others do not.
Because this is a very simple application, I have not bothered with a Header (or Block & Table) section but from what I have read that should not be a problem.
I have attached the test DXF I have created.
I often use Inventor to generate 2D views of things for AutoCAD. Once I get the view into AutoCAD, I want to copy the outline, make a polyline of it, decurve it and make a wipe out of that.
This is all well and good until Inventor exports an ellipse in the drawing. They can't be converted to a polyline. So, is there some way to force Inventor to export them as some other entity type or is there a way to convert them in AutoCAD that I'm not aware of? The only two things I've tried are flatten and explode and neither of them works.
Is there a method of converting ellipses to polylines?

View 4 Replies View RelatedI would like to ask a question on “Break at point”.
It is possible to break a line but for circles and ellipses, my attempts resulted in no break at all (see attached picture).
Does “Break at point” support circles and ellipses? If you have a circle and you would like to make it a ¾ circle arc, or any arbitrary angle, how do you do that?

I drawning 2 circle as radius 250mm.the distance between two circle is 0.08mm I drawing one line segment between two circle and I Expanding line segment as length 20mm.then I offset this line The amount 2.5 mm in vertical side up.
When I trim these horizontal line that are Cross-Being with two circle the Remaining line segment is shorter than real distance between two arcs I thinks its happening?
Also I attached 7 pics I try show my problem.
Also when I want obtain horizontal distance with distance command or by linear the intersection is not start from circumference.
whats this and how I can get real horizontal distance between two arcs
I have an issue with flat layouts, when a draw a round object such as a rolled punched plate it would be nice to have the flat layout show what the hole callout and spacing would be, however with the way i draw the model. the holes come out as an ellipse, attached is a document showing how i drew the model.

I am creating an intro video for a school project and I wanted to know is there a way to keyframe ellipses?I have an 'eye' image as my background and have black solid layer over it. That I can do.
What I am trying to do is, make circles/ellipses varying in different sizes that will make the background appear ( 'eye' ) and eventually make enough circles to amke the whole 'eye' appear.
I'm trying to fill my ellipses with a color - when I right click and choose fill, it doesn't fill it correctly - it merely does as the image below.

View 1 Replies View Relatedwe used AutoCad LT 98 & hasn't changed when opening the same files in LT 2014. All curved lines (arcs) that occur in a recently-opened file look like two straight lines with an angle at the mid-point, so that from a distance they still resemble an arc but not at all when zoomed in. When clicking on the control points, it goes to looking like a proper arc, but the change doesn't hold after the file is saved and reopened. Is there a program-wide setting to change, or do the properties of each arc need to be changed individually?
View 3 Replies View Related1st let me preface this with the fact that I know zilch, nada, nil about solid modeling. But I think the easiest way to accomplish what I'm trying to do is thru solid modeling and export the end result as (3D) polyline
What I have is 2 intersecting arcs with varying radii and ucs values. I'm guessing these could turned into regions and then subtract 1 from the other in order to find a list of intersecting points or maybe a splined pline. Or maybe they could be joined. Either way, if I DXFOUT the solids in R12 format, they become plines
I have access to R14 thru 2012
How to draw two ellipses in perspective and additionally marker on the center? What tools will I need? I'm beginner in Illustrator.
My desired effect:
Using AutoCAD Map 3D 2012 Im exporting a few subdivisions to MapInfo after doing my steps on a MAPEXPORT command to create a .TAB or .MIF / .MID which are the steps do below.
MAPEXPORT --> select format_ .TAB or .MIF ---> select my drawing manually ----> do my coordinate conversion -----> DONE..
When in MAPINFO and ready to open / import the exported .TAB it opens and places the drawings (subdivisions) in its correct coordinate I gave it, but the TEXT and ARC / CIRCLES do not come in to scale at all they are extremely large to a point where they can't be seen till I do a zoom all.
Whenever I try to trim two intersection arcs who have the same bending direction and similar radius, casue it is extremely hard to click on the parts that need to be trimmed off. See attached pic for reference.

View 9 Replies View Related3 lines. 2 arcs. All coplanar, all meet end-to-end.
I set "Units/precision" to 0.00000000 and inspected them. They are all x=0 for each endpoint, therefore coplanar. I also did a point "ID" command and checked each endpoint approaching from both sides and confirmed that each pair of results was identical, so all the ends meet exactly.
I was under the impression that Join or at least PEDIT should be able to combine coplanar lines/arcs that all meet end to end into a polyline. Also, using the Express Tool's "FLATTEN" command doesn't work.
The reason I'm doing this is because I've drawn lines/arcs that trace along the midpoint of a sheet metal's material thickness, and this sheet metal has two bends in it and isn't flat anymore, so converting the lines/arcs to a single polyline will tell me how long the flat plate needs to be that will be ordered to create it.
