AutoCAD Inventor :: Cannot Set Values Of A Sketch Point
Jan 17, 2012
I'm trying to contrain the end points of 2 lines using iLogic. I know the end points but I cannot get the values into the SketchPoint object. The real odd thing is I can create the lines no problem. I tried it 2 different ways shown below. The first way gives me this error..."Object reference not set to an instance of an object.". The second says "Unable to cast COM object.."
Dim oTG As TransientGeometry
oTG = ThisApplication.TransientGeometry
Dim EntityEndPt As SketchPoint
EndPtX = 0 * 2.54
EndPtY = 3 * 2.54
‘Code Fails Here!
EntityStartPt.Geometry.X = EndPtX

I was trying to query some sketch points data from a profile Path using code as below. However the program stopped without telling the reason.
Code below:
i = 0;
foreach (ProfileEntity oSourceProfileEntity in oProfilePath) { switch (oProfilePath[i].SketchEntity.Type) { case ObjectTypeEnum.kSketchArcObject: { SketchArc srcSkArc = default(SketchArc); srcSkArc = (SketchArc) oSourceProfileEntity.SketchEntity; // error points[i] = srcSkArc.StartSketchPoint.Geometry; break; } default: { SketchLine srcSkLine = default(SketchLine); srcSkLine =(SketchLine) oProfilePath[i].SketchEntity; // error points[i] = srcSkLine.StartSketchPoint.Geometry; break; } } i++; }

I use vb.net draw a cube frame (just point and add edge to link points) in 3dsketch. But at the corner, I got only one edge, the others are filled that is a arc is inserted between the 2nd & 3rd edge to the corner point. There is no second edge is extended to that point.
Just wondering why I got the result. There is no fillet command in my code.

How would one add a sketch-point to a midpoint of an arc? For a SketchLine its easy...
oSketch.GeometricConstraints.AddMidpoint oSketchPoint, oSketchLine
However, I can't see how to do the same operation to find the midpoint of a SketchArc. The interface of course has a selection filter for this so I assume the API can do the same?

The screen shot below shows three coincident constraints and a projection icon on the origin.
looks like a projection icon - what does it mean?
I want to delete the three coincident constraints. But when I delete the coincident constraints there is no Sketch origin center point (the sketch origin center point is a square-yellow dot at the x-y intersection). How to delete or move the three coincident constraints with out deleting the sketch origin center point?

I have this assembly shown in the pic. below. I'm trying to create a point or axis in the blue corner points (to attaches something later on) but it just won't let me choose it for some reason. I know that it's possible to to do that (almost sure I already done this trivial thing in inventor.)
Any reason it's not letting me choose the sketch points/line to in order to create points or axis(s)?

I cannot make a plane parallel to a surface and through a sketch point.
I can't also select the sketch point or line in order to make an axis. the sketch point, line from the sketch or anything from a sketch isn't selectable.

It goes f.e. like this:
I draw a line (no constrains) and I can move it by grabing an end or whole line by click&hold mouse button, great.
But after couple minutes of work with part and sketches I can't grab anything. Even on new created sketches and new lines. Click and drag just open rectangle selection. Oh, between these phases there is a phase when 2nd click&hold works...
When I open/create another part it is normall, but this one I must close and open again.

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 know why you cant loop select and offset the rectangle but surley if you are going to take the time to listen to users and create requested tools, you should do it well?

Unfortunately, it's chock full of proprietary customer data, so I can't share the parts or the assembly. But I can pretty well explain what needs to happen, and I've attached a JPG that shows a bit of what I'm doing.
I need to design a bracket to hold an RPM sensor at a certain gap to a spiral bevel gear. I've got a huge assembly model (non-Inventor) from the customer, as well as the model for the sensor. My plan is to start a master IAM, insert the customer assembly, insert the sensor and constrain him, and draw the various hardware I need around the sensor.
So I start by making a work plane that matches the bevel angle and is in a location so the end of my sensor will be flush to that plane. Create a sketch on that plane, then project 2 relevant axes to create the appropriate "origin" from which my location will be based. Place a point on one line, at a certain radial distance and constrain my point.
So now I've got a point and a plane that are where I want my sensing face and my centerline axis to be. What now? I was thinking that I'd create a work axis "normal to plane through a point", but this workflow isn't available in the assembly environment. I can't constrain a solid to a sketch point, so I really don't know what to do at this point in order to put the part where I need it.

I have been searching for a macro to export the start and end point of a line coordinates to excel, but I can only find information on how to export 3D Points.
Is it possible to program a macro that allows me to export the start and end point of various lines in a sketch?
The objective of this is to connect an excel file which is updated when I create a line with it correspondent points, then i could not only import these x,y,z coordinates from excel to inventor but I whould be able to update my spreedsheet whenever I change my sketch.

What is the best way to insert a c3d point with assigned values. For example, I want to insert a point with the style curb stop, on a certain layer with a certain label. Going through thr insert point tool is not very user friendly for users looking to add points, not assign properties. Can this operation be added to the tool palettes? I am not familar with creating my own.

I've created a shared sketch and have used it with various features. Sometime those features are suppressed. The model works fine but the shared sketch generates a sketch doctor error because the feature that created it has been suppressed. Is there anyway to make the sketch suppressed so it doesn't trigger a sketch doctor error? Inventor 2013

How do I duplicate the 2D line work from a part level sketch into a drawing level (overlay) sketch?
I started a simple 2D piping system diagram sketch by opening a new part file and using a sketch to stick draw the system schematic including some annotations. Then I opened a new drawing file and made a base view of the part file to bring a view of the original sketch into the drawing.
I realize now that it would have been much easier to have created the schematic directly in a 2D sketch at the drawing level, which would have made editing the annotations much easier at the drawing level, and there is really no need for the part file to exist. I have no intention of creating a 3D model or "real" part in the .ipt file, was just using it as a jumping off point to sketch.
I was thinking that I could correct my error in judgment by just copying the sketch and pasting it into a new sketch on the drawing, but it doesn't want to work that way. I have tried copying both the whole sketch at the browser level, and the entire sketch contents (all of the lines and annotations) from the opened part sketch, but when I attempt to paste either of those into the drawing, paste does not seem to be an option. I'd rather not have to draw the whole thing again, as in typical fashion, my once simple sketch has grown in proportion and complexity from its simple beginning.

First we imported an ".igs" file to inventor, which produced "wires". Then by promoting the wires it produced a 3-d sketch.
The model is in one plane and 2-D, and we are trying to use Ansys 2-D analysis, but in-order to do so it needs to be in a 2-D sketch.
The model is too large to be redrawn on a 2-D plane, how to convert it to a 2-D sketch

When I edit certain sketched some other sketches disappear. see attached.
This is causing modelling to slow down as I can not project lines from the sketch that has disappeared.

I'm having trouble with constaints, I'd like to constrain my sketch to a point in another sketch on a different plane. Is this posible in Inventor? If so how? If Inventor works differently how would you get a points in one sketch to be linked to points another?

I need to find a way how to insert a point or a * on the center point of a hole and put it on a different layer. The reason for this is - I am a CAD tech for a welding shop and we cut parts out of steel and we use the dxf file format for our plasma table to cut parts. For example : if i have a 1 inch thick plate and want to put a 3/4'' hole in the plate the hole will be distorted because the hole is smaller than the material thickness. For these situation we can use the plasma table to burn a point or a dot on the center point of the hole. But to do this the point or dot must be on a different layer in the dxf.

I have an attribute blocks and this att block has two tag values , is there a simple code for to change 1st tag values automaticly according to 2nd values ?
for example :
1st tag (50x50) - 2nd tag ( 100 ) ==> 50x50-100
if i enter 201 valuse to 2nd tag then 1 st tag has to change as 100x100
if i enter 501 valuse to 2nd tag then 1 st tag has to change as 150x510
I attached a jpg file for explain much better
