I have three contiguous splines. I'd like to make them one continuous entity, either spline or polyline. How do I do?
I've gone to Modify/Object/Spline and to Modify/Object/Polyline and neither seem to work.
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.
So, is it possible to create one polyline that has combined dashed and continuous type of line in one polyline?

when I highlight the spline it will not give me a option to turn the spline into a pline.
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.
View 2 Replies View RelatedI 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.
View 2 Replies View RelatedI need to return the entity name of the largest (longest closed) polyline in a selection set. At this point I have no trouble creating the selection set and even getting the area of the boundingbox, which is not the most accurate way to find the true size, but it's a start. The part that has me stumped is: if I iterate through the selection set, then how can I compare one to the other when I have access to the current entity. I've been staring at examples of lambdas but it seems to me that iterating through the selection set is going about it wrong in the first place.
Below is my current code with a remaining issue. I can return the largest area of the polylines (no good for more than two entities in selection set), but I do not know how to return the entity name:
(IF (> (SETQ SS (SSGET "x" '((0 . "*POLYLINE") (8 . "POOL") (-4 . "<OR") (62 . 5) (62 . 256) (-4 .

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.
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.
View 9 Replies View RelatedThe task should be similar to the _measure command but, I would like to divide the spline into lengths that I give in input. (Decided by user)
e.g. Length of spline: 10.000 meters
Place a block at length:
- 1238 m
- 2005 m
- 2018 m
- 2458 m
- 4098 m
and so on..
How I can do that? It would be perfect if it would be possible to give an excel file with the length values.

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'm trying to create an external involute spline (ANSI B92.2M) Fillet Root Side Fit 26.9mm x 1 mm x 26 teeth x 38 mm long using the spline generator with Inventor 2012. I created a test shaft"M-182-AMA.ipt" that is Ø26.9 mm x 38 mm long with 1 mm radius on each end of shaft.
I use the following steps:
1. After creating component "M-182-AMA.ipt" I select Design tab>>Power Transmission>>Involute Spline.
2. A window appears that has the caption "Involute Splines Connection Generator".In the Dimensions section I choose "Splines Type: ANSI B92.2M - 37.5 deg, Fillet Root, Side Fit, 26 x 1.00 x 38 x 5H/5h" and change the Length to 38 mm.
3. In the Shaft Groove section I use Create new, and I push the Reference 1 button that turns blue, I then select the od feature from the model and I get an error(see attached pic "error1.jpg).
I changed the 26.9mm od to be 27mm and it still gave me the error.

(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.

View 5 Replies View RelatedIs there any way at all to draw a new polyline - from the endpoint of another polyline, and have it automatically join as one polyline from the existing section??
I know this can be done via PEDIT, but its so laborious and soo many clicks, and I have alot of segmented Polylines that I need to consolidate when I draft.
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.
How do you find 'if' a polyline is inside another polyline?

The exterior glazing will be segmented and we are trying to make the building as dimensionally uniform as possible. IE 5'-0" Curtain Wall units. So each arc length needs to be perfectly divisible by 5'-0" and the transitions from one arc to the next must occur at a tangent point.
Eventually we will be developing the building in Revit 2013 but for now we are in ACAD 2013.
