AutoCAD Inventor :: Can't Use Sketch To Create Point Or Axis
Oct 4, 2011
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)?

Is it possible to automatically project the x-axis, z-axis or z-axis onto the sketch plane?
I.e. every time you open a new sketch the corresponding lateral and vertical axis will be projected onto the sketch.

I am using projected and sketched geometry (2D sketches) in assembly space to create lines/ points that I intend to use to define planes and axes. The problem I have is that nearly all the geometry I create (lines and points in 2D sketches) is not "selectable" when I try to create planes or axes. I cannot even put a work points "on top of" my sketch points. Why are my sketches not usable in the assembly space? Since the components in my model are just two extruded rings I don't have any linear edges I can select to make this work/ define planes.

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++; }

As a background....I am coming off of 10+ years using Catia (that's the software the company used) and have moved to a company that uses Inventor instead. I have used inventor for the past year.
In the past (Catia) it seemed pretty intuitive to create the vertical and horizontal during the creation of the sketch in such a way that would reflect the way you would want it defined as a view in a drawing. As well as controlling the preferred screen view (vertical +’ve to the top of the screen and horizontal +’ve to the right of the screen)
As per a previous post....I have tried the "Edit Coordinate System" but find it difficult to control the Vertical and Horizontal axis independent of each other.......
I understand that "functionally" there is no issue...but it becomes quite disorienting in a complex model when going to edit a sketch and the model spins around, showing the sketch in an orientation that doesn't relate to the models features, or "sketch related" features.
It becomes especially difficult/confusing when modifying/checking other peoples models as well.
I just wanted to support the need for this functionality. In the end it just enhances the flexibility of the software and maintain some amount of definable company standard work procedures for modelling.
Maybe it hasn't been included in the software because of proprietary reasons? I would hope there is a reason.....it seems like there are people out there who would utilize it.

How does Inventor decide how to orient the axis for a new sketch? Sometimes, when I create a sketch on a face of a feature, the sketch sometimes rotates to an odd angle (Untitled.png). I can create a sketch on a different, parallel surface and the sketch doesn't go to odd angles. Why does Inventor do this?
How do I edit the orientation? I've attached the part that I'm having the issue in. When I try to create a sketch on the face of the loft, the x/y does things I don't understand.

how to lock sketch features onto an axis or any other reference point. Also, how to bring in reference features (like in ProE)
I am trying to extrude a figure off of one that has already been sketched, and the wrong lines keep moving when I change the dimensions.

i a'm using Inventor routed 2011 and am having a issue with a revolve. I created an axis with a sketch in the part. Than i created a plane that does not pass through that axis. i sketch on that plane than try to revolve using the axis. it gives me an error. what i have is a arm3+"w x 28"l that is pivoting in the in the center and about 9" from the end it tapers out .5". The bottom is the cutting edge that i need to revolve onto a weldment for matching to keep a tight seal.

In my sketch I want to move a smaller circle that is within a circle along the Z-axis. I've put the image below to avoid confusion. I am using Inventor 2012.

I am creating a part that consists of a series of intermediate Lofts. The various Loft termination profiles are sketched on a series of stacked planes, most of which are parallel to one another. I have a Work Axis (oriented at an angle off of true vertical) that penetrates all of these sketch planes, essentially forming a "central axis" for my part. Most, but not all, of my sketch planes are normal (perpendicular) to that axis.
I want to use my "central axis" as a reference point in each of my sketches, i.e., the point where the axis intersects the sketch plane. I am having a minor difficulty.
When I project my central axis into a sketch whose plane is normal (perpendicular) to the axis, Inventor displays a reference point where the axis penetrates the plane and I can dimension my sketch geometry relative to that point. Conversely, no such point is displayed when I project the axis into a sketch plane that is NOT normal to the axis.
Is this correct behavior? To have a dimension able point on my "non-normal" sketch planes, must I create explicit Work Points to mark the intersection between my Axis and such planes, and then project those points into the related sketches?

I just installed a student version of Inventor Pro on my comptuer. I have used this and several other similar software packages before. My problem: when I open a new part file, it takes me to a gray screen. No coordinate axes, view cube, nothing. When I click "Create 2D Sketch," still nothing. Same gray screen. If I draw a line, it doesn't show anything.
I've gone to View -> Object Visibility, and everything seems to be checked off as it should be. I've also clicked User Interface, and it shows the View Cube among other things as being selected.
The software didn't prompt me for an activation key, not sure if that may be relevant to the problem?

I very often find that I would like to create a work plane defined by an axis and a point such that the plane is spanned by the point and the axis. But the only possible way seems to be to create a plane through the point and perpendicular to the axis.

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?

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 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 am trying to create a wheel that can be rotate about the horizontal axis. It should have a hole for axle to fit through. However, when I try to do this it will not let me select the horizontal axis to rotate about. I also tried to rotate about a center line that I created but it wouldn't do that either..

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.

i try to make an animation. I create a cylinder and i want to rotate it by longitudinal axis. i click 'components', select the cylinder and after i click 'position' to select the axis that axis system appears in the right side of the cylinder not in the middle. If i continue whit this settings the cylinder will rotate by a circle not by his longitudinal axis. How can i move that axis sistem in the middle of the cylinder? I can drag it but can't place it exactly in the middle.
