AutoCAD Inventor :: Find Intersection Point Between Line Segment And Workplane
Aug 31, 2011
I have to create a hole (extrude) in a wall part in my assembly document where a stack will be installed.
To determine where, I verify if a line segment pass through the wall (XY Plane).
But I get an error with the command: IntersectWithLine
Here's my
Public Function IntersectionPoint(ByVal app As Inventor.Application,
ByVal wp As Inventor.WorkPlane) As Inventor.Point
Dim oTransGeom As Inventor.TransientGeometry = app.TransientGeometry
Dim startPoint As Inventor.Point = oTransGeom.CreatePoint(Me.StartVertex.X,
[Code] ......
I am trying to create a workplane by a point and a line. I can do this maually, but have not been able to reproduce this in code.
BTW: I realize I can create a fixed workplane by using the point, the edge, and an edge perpendicular to the edge, but I cannot have this as a fixed workplane.
I am trying to create surface elevation labels along a polyline and I am having an issue with the label anchor point. I have created a line label style that uses a reference text to produce the elevation from a specified surface, however when I insert the label the default anchor point for the label is in the center of the line segment and that is where the reference text is taking the surface elevation. I am looking for the elevation of the surface at the start of each line segment, and I do not know how I can make it stop defaulting to the center of the line segment.
Attached is an overview of what my labels look like, where the anchor point is, and the layout properties within my label style. I am using C3D 2012.
Is it possible to select lines (maybe up to 6 lines) around an intersection point with a reference line. There is one intersection point and the lines are around it. And also, both the intersecting lines are in different layers.
How to get the ObjectARX's ArxDbg tool working on autocad 2012. ObjectARX 2010 sample project fails to open in VS2010 express.
I'm trying to figure a "fast" algorithm to obtain the amount of material (in linear distance) between 2 points within an assembly i.e. if I draw a line between any two points P1 & P2 in an assembly, what is the length of this segment that goes through material and what is the length that goes trough empty space?
For now I'm creating a thin cylinder as a new part, place it with one end at P1 and the other end at P2, calculate the interference volume of this body with the rest of the assembly and divide this number by the total volume of the cylinder. but has some problems:
1. It is VERY slow, and I want to call this function lots of times. 3. Is not accurate due to the finite diameter of the cylinder. 2. If the assembly has some interferences, the result is wrong (accounting same volume more than once)
I want to find the intersection point between a cylindrical curve and faces in a body. I have the start point an start vector and a rotational velocity. With this values it should be possible to create this cylindrical curve.
Is there a function in inventor which I can use?
Currently I am using the function "FindUsingRay". But I thing that there is only the possibility to fire a linear function through the body.
Today I found the command "FindUsingVector":
Sub FindUsingVector(OriginPoint As Point, Direction As UnitVector, ObjectTypes As SelectionFilterEnum(), ByRef UseCylinder As [defaultvalue(-1)] Boolean, ByRef ProximityTolerance As [optional] VARIANT, ByRef VisibleObjectsOnly As [defaultvalue(-1)] Boolean, ByRef LocationPoints As [optional] VARIANT,
I did not find any information in the "Autodesk Programming help". what is the difference between this both functions?
Is the argument "UseCylinder" for a switch into cylindrical coordinate system?
I have feature line with elevations that represents bottom of ditch and want to go UP 3:1 slope. also i have edge of road feature line that is higher than ditch and want to go 2% down until it hits side of the ditch that is 3:1. Any easiest way in civil 3d to create intersection line between ditch bottom going up 3:1 and edge of road going down 2%?
When I check with DIST command both the ends of the line are with distance 0.00000000 to the region. But when I apply intersectwith method to them I get only 1 intersection. This is a sample only, I face this issue regularly.

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?)
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))
I would like to use iLogic to find the location of the points of a line, determine if the line is approximately vertical, and apply a vertical constraint if it is vertical.
Here is the code process I envision:
1. Automatically select a straight line.
2. Find the location of its end points.
3. Compare the X-value of the end points to see if they are vertically aligned (or almost so).
4. If they are vertically aligned, apply a vertical constraint.
5. Select next line and repeat.
Is this possible with iLogic? I don't see any way of calling a line's sketch points or finding their location.
I'm running 2002 and I have a drawing with an array of lines (forms a grid ceiling, actually). With OSNAP on I cannot grab the intersection of these lines, however, it does work on other lines in the drawing, as it usually does.
I am writing a routine that will place a piece of text at a specified point along a polyline. My problem is to determine the angle for the text. It needs to be the same as the segment of the polyline that it falls on. Just can't get my head around how to get that angle?
I can get a list of the vertex point of the polyline, but how do I determine the segment the point falls on?
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.
I Posted This problem twice but it doesn't showed in the forum. I don't know why, whatever, My problem is making Array with a circle and a line[same as to radius]. When i use array between them to create 9 more lines, some lines are becomes bigger then the original line. why this happen? I attach a file to be understand clearly. Zoom the intersection point of lines and the circle.
I have a subdivision plat that I'm working on with a curved lot line. When I label this particular lot line, Civil 3D labels it like it's two different segments. In other words, instead of labeling the line as a 100 foot long arc with a radius of 100 feet, it labels it as a 60 foot arc and a 40 foot arc. I can't figure out how to combine the two segments.
All of the lots lines were created from polyline objects, and there was no break in the original line work (nor is there any indication of a break in this location when I select it).
When I draw a line at the origin, it does not find the origin and snap to it, or auto apply the horizontal constraint when near horizontal. Or if I draw an L the lines are not connected. That is, I can pull one line away from the other. I can not find the settingsto correct this behavior. What's up?
I'm trying to get the "Y" intersection of a line I construct and a given polyline using the following code.The debugger stops at this line that calls the function
The error message is "MissingMethodException was unhandled by user code"

I want to put my iFeature on my workplane,but i can't.However, if I change my PlaneInput = oFace , it can work perfectly.My program is below:
Private WithEvents oInteraction As InteractionEvents Private WithEvents oselect As SelectEvents Private Sub UserForm_Initialize() Set oInteraction = ThisApplication.CommandManager.CreateInteractionEvents Set oselect = oInteraction.SelectEvents
Say I'm projecting some 3D polylines to a profile view I have, and the 3D polylines cross the alignment defining the profile view. Is there a way to format the projections such that the point of intersection is identified, and that the points will be updated if I change either the alignment or the 3D polylines?
I have a bunch of lines that are created with multiple segments. I'd like to annotate the total length. I can't figure out to do this without labelling each segment along the line using Line and Curve commands. How do I get one annotation that only shows the total of all the sements?
I made a 3D box shape in AutoCAD. I would like to draw a line on one of the surfaces of the box. Also I know you can use the the linear tool under Annotations to display dimensions of 2D lines. But I don't know how to do it so that it that shows the dimension on a vertical axis as shown in the picture below.
