I have discovered a 3D polyline cant be joined to a 2D polyline and when i exploded 3Dpline then flattened it ,as recommended elsewhere on this forum,it seems its shrunk in length.The NC router I have access to has to use 2D polyline for the path of the cutter.wish i could simply fed the 3D object into the NC router software and that was all i had to do.
View 9 RepliesI used it to clear out the old vertex information, and then add new vertex points.All works on the screen until you use the undo command then all the vertex points are lost. Just created new polylines and deleted the old to fix it. Not ideal as I was storing the ObjectId’s in Xrecords, which now have to be updated with the new id’s

You said that there is no need to flatten, but each method I have tried does not produce a polyline with curves.
I tried:
survfig.BaseCurve
survfig.BaseCurve.GetProjectedCurve
survig.BaseCurve.GetOrthoprojectedCurve
If if manually flatten the figure using a dummy suface with the AeccFeatureElevsFromSurf command, the polyline derived from survfig.BaseCurve will then have actual arc segments.
Is there another method or a way to flatten the figure programatically first?
what is the command shortcut for creating circle from tan tan tan method????
View 7 Replies View RelatedAs 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 trying to create a Solid 3d that is the extrusion solid af a closed polyline by a given height
I select the polyline that i do this
Solid3d s = new Solid3d();
s.CreateExtrudedSolid(selectedPolyline, new Vector3d(0, 0, 20), new SweepOptions());
but Autocad throw an Invalid Input exception.
I've had a problem for a while now trying to extrude a 3d polyline into a 3d solid. The polyline is on different planes which is one cause of why it won't work. Instead of extruding into a solid it only does the sides making it a mesh rather than a solid. If its on one plane I know it will work.
View 2 Replies View RelatedI got a macro job for creation the drawing for a part. I got a lot of problem.
1/ The first one is move view:
I already create a view (e.g. oIsoView), now I want to move it to the left.
I find the DrawingView.Position method, how can I use this method? I try many time, but it's not successful yet.
Do I need to use the SelectSet method??????
I have polylines and changed the width to 3/4" and now the Plines are not solid (filled like a hatch) anymore? They are splined as well. I must have changed a setting somewhere and did not know it. AutoCAD 2012.

View 3 Replies View RelatedHow are people modeling curb inlet bypass flow? When I first got into using SSA, I looked on-line through some AU handouts and blogs etc. I learned to model on-grade inlets using direct bypass links. I would create one that linked upstream and downstream inlets. It appears that hydrodynamic routing is the preferred option for modeling pipe networks with storage nodes, and the direct links don't work due to error 134. It would seem that the logical fix for this is to model all gutter bypass as user defined open channel and create a channel section that matches the road and gutter section. Is that correct? Also, how does the software view a direct link versus open channel?
View 5 Replies View RelatedMany times, we run several individual wires from one device to another. They are not grouped in a cable jacket or anything just individual wires. I was wondering if there is anyway to make the wire routing look a little neater as right now I have to tweak each wire one by one and many times it looks like crap. Can I use a segment for this and then just turn off the visibility of the segment or something? I just want the wires to look neat running from one place to another and there must be a way to do this?
View 6 Replies View RelatedI've got a DWG file generated from a software called 12D. It contains a polyline model of an embankment. I've imported it into Max and wanted to create 3D solids out of it so I can further manipulate this model and render.
I'm struggling to convert it into a 3D solid. I have tried the extrude and loft modifiers, but unable to get them to loft or extrude along the poly lines.
So I' thinking I may recreate the whole object from scratch vertex by vertex. How I can create a solid without recreating the whole object?
Attached a part of it for example here: [URL] ......
I am aware of creating a polyline and using .AddVertexAt() to give the points, my question is if I want to create a polyline in acad I generally will pick a point and then type out @10.5<0 or something similar of that nature to pick my next point. Is it possible to add vertices to a polyline in .Net giving it the distance and angle of one point2d to the next point2d?
Example:
acPoly.AddVertexAt(0, New Point2d(0,0),0,0,0)
acPoly.AddvertexAt(0, New Point2d(1,0),0,0,0)
but instead?
acPoly.AddVertexAt(0, New Point2d(0,0),0,0,0)
acPoly.AddVertex ( use code equivalent of New Point2d = @10.5<0 from point at 0 index)
I would like to create a polyline in a plane that is not WCS. I am able to do so with the 3D polyline. My problem is that 3D polyline does not allow for a Bulge in the polyline.

I am trying to cut out a logo from a 3D solid. Essentially the thing I'm trying to 'cut' is a box, simple. However, the logo I has is reasonably complicated and a conversion to DWG from an Illustrator file.
I have tried creating the whole thing as a surface, no luck
Tried exploding it into both lines, polylines and splines, no luck
The nearest I get is a long winded way round. Im having to joins the splines, then convert to polyline, then convert to surface, then thicken the surface. This would be ok, but there's lots of text and so on.
I just wondered if there's a simple way of doing it that I've missed? Such as "cut these 2D lines out of this 3D shape" command and then delete the sliced out pieces I don't want.
I've read 2013 is going to include line labeling capabilities by selecting 2 points rather than selecting linework. Is there going to be a way to label an area without creating a closed polyline or parcel, where it works the way a hatch works. So if I selecting in the middle of multiple individual intersecting lines, it labels the area.
View 9 Replies View RelatedI'm using AutoCAD Mechanical 2010 and received a .DXF file that contains 'solid' objects. Unfortunately the next tool in my workflow doesn't understand 'solids' only polylines (and a few other basic shapes like circles, lines, etc). Is there some way to convert the object in AutoCAD?
I tried the 'boundary' command but when it asks to 'Pick Points' and I click inside the solid, it always gives the error 'Valid hatch boundary not found'.
What am I missing here?

I'm trying to create a solid body from a non uniform 3d frame Actually I bought this model and it turned out to be hollow inside. How to make it a complete single solid body? [This model is a part of human bone]
I'm having trouble creating a solid from different surfaces.
I already tried the surface stick, but it seems that it is still not a solid. (How can I check this?) The part is still yellow. If I try to apply the sculpt feature it says:
Modeling failure: A valid body cannot be constructed based on the selected inputs.
It 's a quiet complex shape. You find here: [URL].....
I have the 3d model of a ship, but it has no surfaces or solids, just lines. I want to create some solids based on those lines.
It's better if i attach the dwg to the post and explain what i want to do:
- in the file attached there are some lines marked with red and blue
- i want to create a solid/3dobject by extruding/lofting the red lines along the blue lines.
In the drawing only a few lines are colored, for better understanding. I tried with loft, but it only creates some surfaces. The point is that i need a solid or a 3d object.

My ultimate aim for this small drawing is to convert it to an .STL file. For this the shape needs to be a solid or watertight mesh. I've attached the drawing in CAD - it's very basic! I just want to create a solid shape, using the surface, with a flat base up to the lines drawn on. Or even just a surrounding mesh so that the shape can be exported as a .STL. I just can't figure out how to do it!

How do I create this quickly?
whats the difference between creating a width using layers and using polyline width?
