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 .
View 1 RepliesWhen I try to extrude this closed polyline (yes it is closed) I get the message "Cannot sweep or extrude a self-intersecting curve." I do this sort of extrusion all the time (closed polylines with various geometry) and usually have no trouble.

View 5 Replies View RelatedI have tried, such as creating lines in a 3D sketch and projecting the geometry to surface, and creating a work plane, and both don't seem to work for me.... I'm trying to cut out a 5.8mmx14mm rectangle out of a cylinder. When I project the geometry to the cylinder's inner surface, I cannot trim the solid in order to extrude. I've attached the file.

My end goal is to fill in between the grey part and the surface. The surface comes from another part in the assembly, and I used Copy Object to get the surface in this part file. Ideally I would like to do something like Extrude> To Next and select the surface as my terminator. I have done this with success with curved surfaces, but not complex curved surfaces. Does Inventor not handle extruding to complex curves?
Another option I tried was simply extending this part out beyond the surface using the Split feature to trim the part. Again, to no avail. I also tried creating a subassembly of this part and the part the surface is derived from with this part extending beyond the surface, deriving it and subtracting the surface part so I could use Delete Face with the Lump option. No dice there, either.
There was a hole in the side of the surface where I am trying to extrude the part (it is still open on the other side of the surface), but I used Patch and it seemed to fill it in just fine.

i need to create a solid by extruding/offseting a spline surface (attached picture). The problem is, a solid created by simply extruding this surface "outside" would cross itself, so autocad does not allow me to do it (neither extruding, surface offsetting is working) I tried to make a cube then using this surface as a splitting spline - however a solid created this way is flat on z-axis. How can I do this ? Everything is fine with the spline as well as a surface - it's closed one. Obviously the problem is in the fact in the self intersection of the extruded solid. So maybe using it to split a solid is a better approach?

I read on an archived blog somewhere that is was a glitch in autocad2005. I am running 2010- so I don't get it. I really need to extrude these plines
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.

View 3 Replies View RelatedI 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 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 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????
Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.
The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.
I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.
1. Novapoint is quite unstable and crashes alot
2. You cant create profiles out of 3d faces
3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface
4. A large surface made out of 3d-faces demands alot of computer power
So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.

View 1 Replies View RelatedI can draw a closed polyline representing a closed area.
I can then toggle its 'closed' property and it seems to make no difference. area is same, I can extrude or create regions, I can hatch in either case.
in which specific situations we should bother about whether a polyline is closed or not?
I'm trying to create (in 3D workspace), a 3D polyline which starts from the "ground" and goes up the Z axis for 45 units (meters for example), then, the polyline continues "up" but in a 45 degree inclination, and then it goes up further but still 45 degrees from the last segment.
I attached a picture of this to the post, the top line is the one I want to create, and the bottom one is what I get.
The thing is that the 3dpoly command doesn't let me set the line on the Z plane, unless I fix it in ortho mode, and even after I do the first segment that way, the next one stays fixed in either the Z plane or the XY plane, but not in the 45 degree between them that I want....
P.S. - when I click the 3d polyline command, there are no options in the command area, just "specify first point...." - is this what should appear?
As part of a larger job we have surveyed the top of a dry stone wall. The client now wants that we make a solid for him from the surveyed points with a height of 2000mm (the drawing units are in millimetres).
A 3d polyline was created from the lines joining the points and I have that in the attached drawing.
I'm not looking for someone to create the wall, but I'm looking for the method to do it, as it will certainly crop up again with this new client. I've tried many ways in both AutoCAD and Civil 3D but just can't create the solid.
I'm currently trying to use the draw > point > measure tool to create a set of points around a polyline but I can't seem to get them to start at a point that I want. When I try and create the points they start from a random place.
View 3 Replies View RelatedI drew a very complicated 2-D plot this afternoon. The most majority of the plot is composed of different straight lines, arcs. Then I used the polyline function to join them together to form a closed single polyline (Modify->object->polyline).
Later on I want to change something in part of the polyline. Then I used the 'pedit' again, I chose 'open'. But the whole polyline won't break into its original segments. I tried through all the menus, just cannot find the right tool for this purpose.
Does it mean I have to start over from scratch to redraw the whole plot?

My selection set consists of dbpoints that exists on my drawing and they are more or less in line
I create a new point3dcollection with this db points
I want to create a 3d polyline based on this point3d collection
My problem is : how to sort this point3d collection based on a picked start point and picked end point?
The only idea I have is:
from start point i calculate the distance to each point3d from collection and based on the results i sort the point3d collection based on distances.
