AutoCad 3D :: Generate 3D Polyline From Sliced Edge Of Surface
Jul 29, 2011
I was wondering if you could generate a 3D poly line from a surface which I have sliced. I am trying to establish retaining wall heights in a cutting on an embankment. I have generated the slope using 2 3D polylines offset and edgesurfed between them. I then put my proposed footpath at the desired location. When I needed to slice the mesh I had to convert it to a surface. It worked but I now do not have any nodes that I can connect vertical lines to in order for me to design wall heights etc.
Is there a way to generate a 3D poly from the sliced edge of a surface.
I was wondering if there is a way that AutoCAD can automatically generate a polyline (or something similar) that would illustrate the desired direction for a route from linked database information. My taxation/assessment/water department would like a map showing the routes a water meter reader should take according to linked data on parcel rollnumbers. They want an arrow on a line showing a route that should be follwed for each zone/metered area.
I am creating exhibit drawings and legal descriptions for right-of-way and easement acquisitions. I'm using parcels to create the various objects for the exhibit drawings: parcels allow me to label the acquisition, area, and lines and curves. The parcel property gives me a 'mapcheck' description that I use to generate my legal description. All good.
How are people generating this sort of information for polylines? I will have polylines from my POB to my TPOB that I need to describe. I have artificially closed these polylines to create parcels from them so I can glean the information that I need, but that feels like a work-around.
I have generated a TIN surface and change the style to "Slope". I want to create a legend for the surface, but the legend has no content, only the header.
The question is 'how to generate ribs out of surface, to machine from wood and assemble the skeleton for doing fiberglass'). URL....Someone generated those wooden ribs, machined it and assembled the shape to fill inside with stereofoam (say), and cover by fiberglass to generate mold.
I failed to find any kind of tutorial that answers "how generate such ribs out of a surface at hand".
I would like to know which of the following software can be used to generate a 3D model/surface using the key points. The key points were obtained from 4 images after spline-fitting.
1) ACIS Reader 2) AUTOCAD 3) Autodesk Inventor ( Associative Geometry Interface and Reader (Merged/sewn work surfaces are not supported. ) 4) CATIA Reader 5) CATIA V5 Associative Geometry Interface and Reader 6) Creo Elements/Direct Modeling 7) Cero Parametric (formerly Pro/ENGINEER ) Associative Geometry Interface and Reader GAMBIT Reader 9) IGES Reader 10) JT Open Reader 11) NX Associative Geometry Interface and Reader 12) Parasolid Reader 13) Solid Edge 14) SolidWorks Associative Geometry Interface and Reader 15) STEP Reader
or any other CAD software whom models can be used in ANSYS 14.0.
I do a lot of visualization work I need a corridor top surface split by material FAST. before I used Corridor Solids but I don't have the extension in 2013. So I export to CivilView, so far so good, then attempt to roundtrip the mesh back in Civil3D and that is where things fall apart.
Export to DWG is not split by material
Export to 3DS results in a blank screen
Export to FBX comes in missing large chunks of mesh out of scale and in the wrong location
I have created a series of splined lines into a polyline (pedit) which I want to extrude. When I extrude the polyline I only get an extruded polyline and not a surface. I need to create a mesh or make the surface a face to extrude to make a solid. I have not used AutoCad for some years and have forgotten how to do this. I know that I am making an incorrect procedure here somehow.
I am wanting to digitize a geology map using AC Map 3d. When I draw 2d polylines of geology units, I would like to be able to drap these onto a DTM suface so I can have them in 3d. How do I do this?
I want to draw a 3D-polyline and wrap it to a surface so that the elevations in the surface aplies to the polyline. With every elevation difference i want a vertrice to be added to the polyline so that it follows the surface perfectly along the polyline length.
how to convert polyline object (with x, y, z) to TIN SURFACE BECAUSE IF THIS OBJECT STILL POLYLINE OBJECT, I CAN'T RUNNING CATCHMENT AREA, ADD LABEL ETC
I need to convert my surface boundary to a polyline so I can use it to clip another surface. Is there a simpler way than tracing it with the polyline command?
How do I go about extruding an open polyline to create a surface? I am able to extrude a solid 3d from a closed polyline ( by creating a region first) but I cant find a way to do the same for surfaces.The autodesk.autocad.databaseservices.Surface class does not have an extrude method unlike the its solid3d equivalent. I am using autocad 2012 .
I have started to use CIVIL3D 2007 instead of LAND-DESKTOP 3.
My question is: When I used LDD I created a surface, then drew a polyline and by right-clicking chose "Project object".
This option produced many new points along my polyline which I used for my design.
When I tried this with CIVIL 3D I couldn't find this option.
I can create a quick profile, however, this is not good for me because I need the data as a collection of points with coordinates & elevation, and not as an image.
Is there any way to produce a projection on a surface (from a polyline)?
Or getting some information from the quick profile in the way I need?
I have been using AutoCAD to create product designs (baby bottles) for the last three years. I am normally drawing lines, arcs and splines to create the shape, then I use PEDIT to create a closed polyline and REVOLVE to create a SOLID 3D object from that shape.
Couple days ago, AutoCAD is not longer creating 3D solids when I use REVOLVE as usual (even using older files and/or the same shapes or polylines that I have used before to create 3D solids). The result of REVOLVE is "SURFACE (REVOLVE)" (I got that from properties). But, the most uncommon thing is that AutoCAD is revolving fine one or two times per day after many many tries. (normally I am closing and opening files and trying to revolve some stuff many times, using the same process and suddenly it revolves the sahpe as a 3D solid)
I attached a picture showing two objects created using the same group of lines, splines and acrs. One is a solid 3d object and the other one is a surface (revolve) as result of using REVOLVE command. WHY????
I have a proposed surface that has been made by selection polyline with a z elevation as contours. Is it possible to have civil 3d easily change the weeding and supplementing factors to a tighter value after it has already been made?
I am building a Crankshaft. How to build the connecting weights that attach the main journals to the connecting rod journals. I can post a screenshot of the design. I have a extruded face that is a half circle on the top.so I am trying to fillet or cut a section off of the rounded edge. I have tried to build tangent workplanes and projecting geomety, but to no avail.
Is there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?
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.
I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(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.
I designed a layout in PS and sliced the menu/btns as well. My btns are in the left side and in the right is the txt box. Whats my problem is when I add txt (a long txt msg) to the txt box the menu/btns in the left they strech downwards and lots of gap is made between the btns. So i am trying to make that menu remain in that same position and i can add the txt to the right.
