AutoCAD 2013 :: Distinction Between Intersection And Apparent Intersection In Snaps

Sep 15, 2012

What distinction is between “intersection” and “apparent intersection” in snaps,. I’m not sure what difference is between the “intersection” and “apparent intersection” in snaps.

AutoCAD Inventor :: Apparent Intersection Not Working?

Jan 22, 2013

Having problems dimensioning to an apparent intersection in an IDW?

Once I hover over both lines to show the intersect and both line do intersect but it should turn green, it's not, it just keeps yellow.

It is placing the dim in the right place but it's also not drawing in the intersect lines.

It was working last month as I have a drawing to prove it.This is on a few machines.

Also moving dimension is a problem. Sometimes they will not reattach after moving one end.

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 :: 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 Inventor :: Ordinate Dimension To Apparent Intersection? (but Not Using Ordinate Set)

Jun 11, 2013

There was a message on here about using Ordinate Set to create an ordinate dimension to an apparent intersection and I've managed to do that, but is there a way to use just Ordinate to dimension to an apparent intersection? I've tried dragging and right click menu but no luck.

I'm using Inventor Professional 2012.

AutoCAD 2013 :: How To Constrain Object Based On Intersection Of Two Other Objects

Nov 12, 2013

Is it possible to constrain the location of one object based on the intersection of two other objects (for example, force the midpoint of one line to be at the intersection of two other lines?)

The reason I want to do this is specific to Civil 3D.

I accidentally turned something on in Autocad, and I want it to go away, I have no idea what it's called or how to get it gone.  It's akin to the "select other" window in Inventor when you select at the intersection of several objects.

How do I make this go away?

AutoCAD .NET :: Why Only 1 Intersection Point Instead Of 2

AutoCAD .NET :: Divide Polylines By Intersection?

Jun 26, 2013

I have drawing with lots of pol)lines which are intersecting themselves.

I would like to divide all selected lines by the point of intersection. 

I have this

[CommandMethod("BRA", CommandFlags.UsePickSet | CommandFlags.Redraw)] public static void TestIntersectAllLines() {
Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument; Database db = doc.Database; Editor ed = doc.Editor;


But it seems to doesn't work properly - some lines are not erasing, some are not intersecting in each point.

AutoCAD 2010 :: Point Of Intersection

May 9, 2013

Isn't there a command that allows you to pick 2 lines and snap to the point of intersection when dimensioning an object with a fillet/chamfer? Typically I o-track it with apparent intersection with no issues, but its a little more difficult when your working with sloped lines, tracking doesnt like to follow angled lines. (Maybe its inventor that I'm think of that can do this?)

AutoCAD Civil 3D :: 4 Way Intersection Targeting

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 Civil 3D :: Relocate An Intersection

What is the best way to relocate and intersection (created with the wizard) from 43+00 to 40+50? I dragged the alignment but the return baselines don't seem to come along for the ride. Would it be better to bite the bullet and redo it?

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 Map 3D :: How To Do Multi Line Intersection

Aug 11, 2011

I have a drawing file in AutoCADMap 3D 2011 consists of some administrative boundaries and city boundaries. Now I have roads of multi line style in the same drawing. When I completed the drawing I noticed there were missing intersections and I wanted all the roads to look something like the drawing shown below.

Please look into the word file thats how I wanted to do intersection in my drawing. Is it possible to do this action in one command or tool.

This is how my drawing looks like. This is how I want the drawing to be.

AutoCAD Inventor :: Dimension To Intersection

Sep 5, 2012

When I place a centerline (or include a workplane from the ipt) is there ANY way to dimension to the intersection of this centerline and the edge of an object?

Like in this image above, I would like a horizontal dim between the vertical centerline and the intersection of the centerline and the edge of the part.I know that I can create a sketch on the view and project geometry/draw geometry... but that is such a pita.

AutoCAD .NET :: Why Intersection Point Does Not Lie On The Curve

Aug 4, 2013

I find intersection of two curves with interop
Dim Zinters As Object = DuvarObj.IntersectWith(MainObj, AcExtendOption.acExtendNone)
then pass the intersection points pt1 and pt2 to managed code to get length of the curve between two intersection points , but I realized that sometimes decimal numbers maybe 10th after comma is different than the curve's start or end points. And so the code below throws error, since point pt1 or pt2 is not exactly on the curve, but they are the intersection points excatly.

What can I do?
Dim dist1 As Double = ent.GetDistanceAtParameter(ent.GetParameterAtPoint(pt1))Dim dist2 As Double = ent.GetDistanceAtParameter(ent.GetParameterAtPoint(pt2))

AutoCAD 2010 :: Can't Snap To Intersection Point

Jul 10, 2012

Form Autocad 2000 to 2012, there is always with this problem. It happens sometimes in object snap, it does not work to snap a intersection point (two crossed lines) when drawing a line or arc or others. For sure, these two lines are in the same plan and can be filleted or chamfered. So I turned on the Apparent intersection, it works with apparent intersection point, I am not sure if this apparent intersection will cause other problem. I am working on pure 2-D drawing, do not want to get any 3D objects inside the drawing.

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?
