AutoCAD Map 3D :: Trim Or Break 3DPolyline At Specific Z Coord
Jul 2, 2013Say we have a line that goes from 0,0,0 to 10,0,10.
How can i trim or break that line (or snap another line to it) at a specific z coord? say at elev 5.51?

AutoCAD Visual LISP / AutoLISP :: Break To Break At Point Command
Mar 19, 2010Is it possible to change te Break command permanently in the Break at Point command?I never use break, only break at point.
Changing te macro for break ^C^C_break to the macro for break at point ^C^C_break \_f @ doesn't work.
To do it manualy at the command prompt takes to much keyboard entries and mouse clicking.
AutoCAD Visual LISP / AutoLISP :: Change A Specific Attribute From Specific Block To Specific Value
Dec 7, 2011I've had a simple lisp I've been using for years that suddenly disappeared. It required that you identify a block name, tag name, and the value that you want the tag to be. All of this is performed via command line, so it is scriptable. Since I lost it, I've been experimenting with -attedit. This command comes frustratingly close to what I'm looking for, except it only appends an existing tag, or replaces a specific string within the tag; I can't get it to replace the entire tag, regardless of its value.
1> Any lisp routine that does what I describe?
or
2> How to make -attedit replace a tag value without regard to what the value currently is (like a * wildcard)?
AutoCAD 2010 :: Sweeping Along A Complex 3DPolyline
Apr 16, 2013I am modeling an ASME pressure vessel with a 2:1 semi elliptical head upon which there must be a couple of lines of .375" trace tubing. I created a 3dpolyine that is the center line of this tubing, and joined all the segments into one so as to be able to sweep the whole thing and make one solid of the tubing run, but it simply will not sweep. I get a message this it is "unable to sweep the selected object." If I break the 3dpolyline, I can sweep parts of it, but the more complex the line segment, I again get the error message. I have attached a copy of the tubing centerlines.
The one on the left is the joined 3dpolyline, the one on the right is the 3dpolylines unjoined. (These were achieved using an intersection command of a rotated surface--the head profile--and an extruded surface--the tube tracing plan layout.) I have done this before, but only with the unjoined 3dpolyline, as in the right-hand example, but that is very time consuming as each segment must be swept. But I recently acquired a third-party LISP routine that joins the 3dpolylines into one. I'm thinking there must be a limitation on data of the 3dpolyline preventing the sweep, and wondering if there is a setting or system variable that will allow the more complex 3dpolyline to be swept.

Nov 5, 2013I've tried doing a block that automatically updates the X and Y coordinates from its moveable leader. I can get it to work in model space or paper space. But my problem is I want it to work in PS, but update with the MS coordinates through the viewport.
I can get it to update, by LISP, by picking a point and passing the points to the blocks attributes. At the moment I have a LISP when actioned it locks the viewports, activates the viewport, and asks you to select a point. Once selected it de-activates the viewport (going back into layout tab) then asks which block you want to update. Where you now select the block and it updates the coordinates. I.e. manually pick the point in MS, switch to PS and then manually pick the block. Then I have to manually modify the leader to the correct location.
I'm hoping that I can (In PS) move the end of the leader to snap to a position in MS and the coord updates to reflect the correct MS coordinates. I'm thinking that maybe this can't be done automatically and that I maybe can move the leader but I'm not sure how I can do it without running a LISP to update the block?
I'd be happy moving the leader then just running a single command and the leader coordinates updating without having to select the points and the block again.
I've attached the block showing the auto update of the attributes (fields).
AutoCAD .NET :: Rotating 3DPolyline To Check Z-value Of Vertices In Top-view Mode
Apr 7, 2013I am trying to rotate a 3dPolyline, so that I can check(view) the Z-value of vertices in the top-view mode.
The following is the example which I am trying to achieve.
The white 3dPolyline has vertices at each intersecting point with the contour lines. Each vertax has Z-value.
I want to rotate this white 3dPolyline in 3D, so that I can make the red 2dPolyline. (Z-value becomes Y-value)
And the start point of the white 3dPolyline becomes the left most point of the red line.
The end point of the white 3dPolyline becomes the right most point of the red line.
Currently, I am doing this by making a new 2dPolyline, manually inserting Z-values as Y-values.
But it looks like my code can be neater if I use TrnasformBy(Matrix3d.Projection).
I am not good with Geometry, so how to use this Matrix3d.Projection.
Need a quick code snippet to make this function? (preferably in C#)
AutoCAD Civil 3D :: River Bottom Surface From 3DPolyline Sections
Sep 4, 2012Is there an easy way to create a tin surface from 3d polylines that are generated by actual measurements of a river/ditch or imported from Hec-Ras (River Analysis -extension)?
The problem seems to be that the triangles should be long and narrow (like the ditch bottom in the example) instead of normal triangles the triangulation method normally generates. (The triangles in the example are generated by 3dwin -program).
When using Hec-Ras one way to go around this problem is to interpolate sections (XS:s) with very short distance. Hec-Ras does the interpolation very well, but I would like to have a better solution without tricks with other programs. Also in the long rivers the result is a very large file.
AutoCad 2D :: Reduce Number Of Vertex Points In Polyline Or 3DPolyline?
Oct 9, 2013Any way to reduce the number of vertex points in a polyline or 3d polyline and retain the basic shape but without having to redraw over the top it?
Ideally, I would like any adjacent segments which are in the same direction as each other to become one segment.
In my image you can see the number of points it has, the majority of which are not necessary for my needs (it was imported from a client's drawing). My desired linetype will also not show because of this.

AutoCAD 2013 :: Can't Trim Circle TTR
Apr 13, 2013I drew 2 circles with ttr command (1 and 2). The problem is when I try to trim them to remove the part I don't need, it doesn't work cause the circles 1 and 2 aren't stick with the borders as they should. At the 4 red circle points, if you zoom you'll notice they don't stick the border, never faced this problem before (usually I cut the part I don't need without problem). I've done regen/all but doesn't seem to fix that problem.

Aug 21, 2013I'm using Inventor Pro 2011 and I'm trying to break the association of a BOM from it's assembly. My company uses a "next assembly list" on each drawing to show the quantities and information that appear on the BOM in the next level assembly. To achieve this we insert a parts list referencing the next level, then we turn off the visiblity of all the parts except the item we want shown. The problem we've found with this is that we're using some large assemblies and Inventor slows down when it has to reference the large assembly on each drawing. All we really want to show is the single line. If we break the link to the large assembly, we feel that it will speed up the process considerably.
