AutoCAD Inventor :: Sketch Origin Center Point
May 6, 2013
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?

After I create a sketch, how do I center it about the origin? The origin is projected, I just can't figure out how to set the sketch about it.

I cannot select origin to constrain sketch with dimension to origin?
I selected Sketch,
expanded origin,
selected mywork plan (xy)
drew rectangle,
input dims,
right click for marking menu,
selected dimensions,
Origin is yellow,
cannot select it and then edge of rect to set dim that will center sketch on origin? Just like the videos show, but cannot select origin>

How is this accomplished in Inventor? The 3D sketch environment seems intentionally crippled. Many of the constrains are not available, and the "include geometery" command refuses to include the origin (or any other planes and axis for that matter).

I'm wondering if there is a way to annotate from the origin without having a long diminsion line to the center. (see image) I want it like the 'linear diameter' but not with double my size. I always have to annotate the projection from center and this would be easy much more easy to do.

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 have just installed Inventor 2012 and am experiencing a bizarre problem with placing content center parts. When I start a new assembly, and place a content center part, I would expect it to locate itself central to the assembly origin. What actually happens is that it grounds itself wherever I click on the screen. This doesn't happen with parts that I have created myself.
Is there a bug in the system or maybe an option that I have unknowingly switched off?

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 made a bunch of lines, then used the bend command to make curves where they intersected. I'm trying to put lines connecting A to C and B to D. How do I constrain the ends of the lines to the center of the curves?

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.

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

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?

In Photoshop / Illustrator, when I create a polygon, and rotate it around it's center point it wobbles. When I scribe it inside of a perfect circle, and rotate it around the circle's center point it rotates smoothly. Basically proving that (at least according to these Adobe products) that the center point of a circle is different than the center point of a polygon scribed inside of it.
An image – the dots in the center are the corresponding center points according to Adobe:

This is incorrect according to basic math. Is Adobe aware of this bug?

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?

I made a complex assembly from Solidworks few years ago. I imported it to Inventor 2012. How can I find the coordinate of the center point of the: a) parts/sub-assemblies, b) the complex assembly as a whole? Under Application Options, I have already checked: Sketch->Display->Coordinate system indicator. Under the assembly tree, I can go to the Origin of each sub-assembly/part and make the corresponding Center Point visible. However, I want the x,y,z values.
I copied and pasted a sub-assembly/part to a new assumbly file and then used VRMLout to export. When I imported the .wrl files to another application, the location of the parts/subassembies are not correct. I think they all became (0,0,0).

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.

way to redefine a point that was placed in a model with a "Center of Loop of Edges" command? Inventor doesn't seem to recognize type of placement unless it's been selected from the Point drop-down menu, but picking this in the midst of a redefine only creates a new point, it doesn't redefine the original point.
As it is, I've been forced to just delete the original point, create a new one and go from there.

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.

How do you hide the origin point using autocad ordinate dimensioning. When I zoom extents there is a point at the origin and is some way from the actual drawing?
