AutoCAD Civil 3D :: Intersection Lines Between Two Surfaces?

Oct 15, 2013

I wonder how to get intersection lines between two surfaces in Civil3D API. It seems that the "MinimumDistBetweenSurfaces" command in Civil3D can do this work. But I can't find corresponding API.

AutoCAD Civil 3D :: Feature Lines / Surfaces And Object Viewer

Jul 19, 2013

When I use Object Viewer to look at just feature lines and surfaces, the feature lines do not appear at the same elevation as the surface as I shift the view around.  Why is that- especially since I am looking at the surface I created from those same feature lines? 

is that a feature, intended to make it easier to discern the feature lines in Object Viewer?  Or a quirk of my video card?

AutoCAD Civil 3D :: Create Intersection Design Using Intersection Tools

Mar 6, 2013

I am trying to create an intersection design using the Intersection Tools in C3D 2012.  I followed the steps in the tutorials, created a corridor on the major road, splitted the regions, created the intersection and added it to the major road corridor, and connect the regions with the intersection portion. 

I used the same assembly throughout the design just for simplicity, however, i notice that there are gaps of curb between the curb return section and the through section (as outline in red rectangles).

AutoCad :: Can't Get Intersection Between 2 Lines

Feb 9, 2013

I'm trying to find the point where 2 lines intersect. I extend both lines so they cross. But when I try to draw a point over where they cross & select intersection on the snap menu, it will not snap to where the 2 lines cross. I've attached the drawing.

AutoCAD .NET :: Calculate Intersection Between 2 Lines

Nov 19, 2012

I'm using AutoCAD 2013 x64 and VS2012 Express with ObjectARX 2013. Now I want to calculate the (projected) intersection point of 2 (intersecting) lines in

After selecting the lines I have this line1.IntersectWith(line2, Intersect.OnBothOperands, intpts, 0, 0) 

In Visual studio express 2012 I get the following warning for the above line of

warning BC40000: 'Public Sub IntersectWith(entityPointer As Autodesk.AutoCAD.DatabaseServices.Entity, intersectType As Autodesk.AutoCAD.DatabaseServices.Intersect, points As Autodesk.AutoCAD.Geometry.Point3dCollection, thisGraphicSystemMarker As Long, otherGraphicSystemMarker As Long)' is obsolete: 'Use the overload taking IntPtr instead.'.

So, if I'm reading this correctly, this method is outdated and I should use an other method to calculate the intersection. But I really don't know what 'Use the overload taking IntPtr instead' means.

One of the things I found is a function that contains this line of Dim inters As Point3d = line1.IntersectWith(line2)(0). This one looks almost the same, but doesn't give me the warning when I compile the code, but this method crashes AutoCAD when there is no intersection between the lines. This is despite a try catch block that surrounds the code.

For now I just want to use lines, but I need to expand the code so it will also work with circles, arcs and polylines.

AutoCad 3D :: 3D Lines To Surfaces?

Oct 24, 2012

I regularely work with CMS (cavity Monitor Survey) data that is typically provided to me as a collection of triangular 3D faces that represent the interior surface of an open cavity within rock.

These files typically have 30,000 to 80,000 faces.

The last time I requested a survey the consultant indicated that their scanner was out of the country for repairs, but that they could generate a similar model by a different method.

What they did is shot many survey points then manually drew lines between them to give the outward appearance of the the normal deliverable. To the surveyors credit, he drew 3,800 lines to generate this wireframe.

My problem is that I normally have to slice the scans to provide planar outlines to our design engineers... and I can't slice lines.

Any way to generate these surfaces automatically? Is there a lisp out there for this? Essentially I would like to shrinkwrap it.

Working in AutoCAD 2000, but also have MicroStation V8 and MineCAD. MineCAD has a Tessellation function that is partially successful, but tends to join points together incorrectly and "fills" my cavity with random surfaces.

AutoCAD Architecture :: Trim Lines Of Apparent Intersection?

Jul 3, 2012

I'm using ACA 2008 and used to be able to pick two lines that didn't physically cross each other and use the trim command to trim them based on where they would cross if they extended to each other.  But it doesn't seem to do it anymore.

Best way I can describe it is it used to trim at the apparent interest ion of where they would come together.  I'm sure there's some easy fix to this, just don't know where it's at.

AutoCAD Civil 3D :: Intersection With Medians

Jan 14, 2013

I am "trying" to design a intersection that contains four lane divided road. Northbound and Southbound lanes are 2% normal crown with a curbed median. I have alignments for each crown. The intersecting road is not crowned. This road is a retrofit so I am limited quite a bit so the intersection wizard is out. We're going old school with this one.

AutoCAD Civil 3D :: Aligning Different Subassemblies At Intersection?

Jul 23, 2013

issue with my Corridor.  It involves the intersection of a main road alignment and a secondary road. Thing is my main road has a 6' shoulder whereas my secondary road doesn't have a shoulder at all. I used the Intersection Wizard to create the Intersection, but the two templates don't align. Without the shoulder the ditches don't line up. I tried drawing a polyline between the two ditches and targeting it and that worked, but then realized that going from 6' shoulder to no shoulder wasn't working either so when I tried to target a polyline from the 6' shoulder to the edge of pavement all kind of stuff happened that didn't make sense to me.

AutoCAD Civil 3D :: Intersection On Looped Corridor

Mar 12, 2013

I have a site access road that extends from highway into site and then loops around and intersects with itself. Would like to keep this as one alignment in order to make Super Elev and master alignment easy to control across project team.

Issue is, we would like to use Intersection wizard at the intersection but cannot, as we ony have one alignment. We could model the intersection the old way, using kerb returns with design profiles, but as the design is still in early stages the intersection is likely to be frequently revised.

how we could utilise intersection wizard in this scenario?

AutoCAD Civil 3D :: Intersection - Curb Return

Feb 7, 2011

C3D 2010 user

I have a problem modeling intersection. This is first time I am modeling intersection. I have gone thru' and actually did all intersection tutorials offered by C3D and naturally I felt like I am ready for it.

But in real world I am not. I am trying to model intersection and I keep getting error as "Value on Wrong side of alignment to profile". I looked at target mapping and thinks so that all is okay (may be not). I am attaching snapshot of error message as well as plan view. I wanted to forward actual dwg but size is too large to post.

Point to note:This is Left lane driving setting. I realized this after I created alignment/profile/assemblies but before I tried intersection modeling. 

I did 8 iterations before this post.

AutoCAD Civil 3D :: Intersection Surface Error

My corridor surface randomly bounces from top links to bottom links through the intersections even though I specified top links only and my corridor is modelling correctly.

Previously I just deleted the surface and recreated it with no errors but it doesn't seem to work now. This happens with both manually created intersections and ones created with the intersection tool.

AutoCAD Civil 3D :: Intersection Of 2 Corridors On Curve

Dec 26, 2013

I have a mainline corridor which is intersecting with a side road corridor that is curving towards the mainline. After the PT of the curve, the two alignments are parallel and I am using an offset assembly here for the sections. What is the best way to handle the area where the two corridors are coming together. As far as I've been able to tell, I cannot use an offset assembly through the curve. There will be a ditch between the two that needs to be shown someway or another. I've attached a screen shot.

AutoCAD Civil 3D :: Create T Intersection With X Alignment

Jun 20, 2012

The street is a 'T'.  The alignment is extended... Sta 0+00 starts 100' back and the intersection at centerlines starts at 1+00.  The alignment is masked between 0+00 and 1+00, but that obviously doesn't make a difference for the intersection wizard.

The intersection wizard does not give me a choice, it just presumes a 4-way intersection.  How do a do/choose a 3-way 'T' intersection in this case?
