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.
View 2 Replieshow to change the elevation of each vertex on a polyline so that each vertex has a different value. The way I attempted this in the past was to click on polyline, click properties and give each vertex the required elevation. However when I looked back at the values I noticed that every vertex had the same value as the last elevation value entered. is it something to do with ensuring polyline is 3D?
View 2 Replies View RelatedDue 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.
I have one drawing but this is Spline but i want to convert it into polyline. without tracing it. i attach my dwg file with this massage.

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 ?

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.
i have some existing drainage pipe and structures in a base plan that i need to change the invert (which is the easy part) and the top elevation to the existing top elevation that does not meet the minimum presect in civil 3d 2012 is there a way to change these min. to match my exisitng elevation for example i have a catch basin invert is 15.45 top is 17.56 with a 18" rcp the cover will be less than 12" and i need to change this.

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?

View 3 Replies View RelatedHow do you label a polyline with a Z elevation that is not part of a surface? want to label the contours, but they are not part of a surface.
2013 Civil 3D.
I create contour line in TOPOGRAPH program, and I import these polylines to AUTOCAD. I have to set elevation for each polyline manually, and I waste a lot of time doing that.
So looking for lisp doing that automatically. I mean, invoke the command, set the first elevation and them select the polylines.
e.g. The first elevation is 530. The next polyline that I select is 531 and so on.
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.
View 9 Replies View RelatedI'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.

View 6 Replies View RelatedI assume nobody has been able to create a parametric part used for storm pipe networks that can have the pipes attached to a point within the structure other than the insertion, or have the elevation read from a point other than the insertion.
With that in mind, we are trying to develop a tool that would allow us to pick a strucutre, and set its "rim" elevation to a point on a proposed surface that is not at the insertion of the strucure. I am decent with lisp, but have not attempted to gather info from random points on civil ojects.
How to change coordinates of polyline ?
I know how to get the coordinates but I need to get and change one of the coordinate.
I'm looking to change an elevation of a survey point within a drawing. I can see where it is possible to manually unlock the points from the Survey Database to allow the user to edit the point. I'm not seeing a method or property in the API Help for 2013 to do the unlocking with code.
Also is it possible to convert a Survey Point to a regular Cogo Point through the code? Or do I have to delte the point and then recreate it as a COGO point? I think this will be my work around if the above doesn't work.
