AutoCAD Inventor :: How To Create Sketch Geometry Used To Define Planes / Axis And Points
Nov 6, 2012
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 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?

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 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 need to create about 100 off points in a sketch.
I have the x and Y co-ordinates in a excel spread sheet. Is there any simple way to create the points other than manually entering thru precise input.

I need to downscale whole assembly if its possible. If not, its no problem for me to downscale every single part separately (apx. 30pcs) and then put it together again but I need to downscale it with all its modeling history - sketches, planes and other geometry. I can't select them when using DERIVE function.

They are all gone in my parts and assemblies. Only are they visible in the browser when I open a particular part or assembly of the parent. Need them for constraints .

I want to draw a line between the two sketches visible on the image below. The line should be in the plane visible. The starting point of the line should be from wherever the top sketch intersects the plane of the current sketch. The finnish point of the line should be wherever a line of the bottom sketch intersects the current sketch plane.
There is no tooltip appearing that would allow me to quickly "attach" the starting line to the correct position. Is there such an aid, and how do i turn it on?

Is it possible to split a 3d line with planes.
I am not able to find a Split method on Sketchline3d.
{Code}
Sub Split_Lines()
If ThisApplication.Documents.Count = 0 Then Exit Sub
If ThisApplication.ActiveDocument.DocumentType <> kPartDocumentObject Then Exit Sub
' Check to make sure a sketch is active.
If Not TypeOf ThisApplication.ActiveEditObject Is Sketch3D Then
MsgBox "A sketch must be active."
Exit Sub
End If

Basically, I have two workplanes which are parallel to each other and offset by a certain distance. As illustrated in the picture below, I'd like to constrain points from each plane to have the same vertical alignment as those from the other plane (horizontal too, I suppose, but the horizontal dimension will be the same anyways).

I have an alignment for a natural gas pipeline.
I want to use the 'Create Points at Alignment Geometry' tool in order to label only the PIs. However, when I use the tool it creates two points (one called PI and one called CPI) at each vertex of the alignment. How can I fix this issue and toggle the creation of the various other geometry points?

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.

Is there a way to quickly remove all geometric elements that have been projected upon a sketch?
I don't want to remove the constraints that lock them. I want to remove the elements that basically have that constraint.

We just upgraded from 2011 to 2013 and we are having SERIOUS problems with our projected sketch geometry in parts not updating. We have only done this about 1.1 million times over the past four years and now every one of our skeleton models we touch is failing to update and causing a whole mess of delays.
I looked through the Application options for sketching and didn't see anything.

I have an existing sketch and a new sketch onto which I want to project some lines from the existing sketch.
The panes of both sketches do not run parrallel.
Normally a projection is created by imaginary projection lines from the existing sketch to the new sketch perpendicular to the new sketch.
But now and want to project the existing sketch with imaginary projection lines that are perpendicular to the existing sketch.

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.

Is there a way to hide project geometry from model sketch? I am modeling a sheetmetal part where I need to sketch centermaks, part number etc. for laser cutting. I want to use xy planes for symmetry reasons when sketching, but I don't want them to appear in dxf. This is a problem if I create a dxf directly from the model.
Usually I create dxf files from drawing by adding new sheet where I create flat pattern view from the spesific part (excluding machinigs etc, only thermal cut boundaries visible). In the drawing I am allso able to show model sketches and hide unwanted project geometry. Is it possible to include these sketches to dxf?

In an assembly document, if you want to project a sketch from one part into another, you go through these steps:
- select the part
- edit the part
- create a 2D sketch
- select the plane
- select project geometry
- select the sketch in the other part
- finish sketch
This creates a reference to the original sketch, so if I move the original sketch the new sketch will also move when I hit Assemble.
I am trying to do the same through the API, so I create a proxy for the original sketch and a proxy for the new sketch. I then use the AddByProjectingEntity method on the new sketch proxy passing the original sketch proxy.
This works for projecting the sketch, but it doesn't create the reference, so if I move the original sketch the new one doesn't move, even if I hit Assemble. How to create this link between the two sketches?

I wish to delete all project geometry in the active drawingsketch with 1 click
But unsure how to get to these constraints.
Are these geometricConstraints?
What I have now doesnt work:
Select Case ThisDoc.Document.DocumentType
Case 12292:
Case Else: MsgBox("Current Document not a drawing document")
Exit Sub
End Select

I am unable to select Sketch geometry via a crossing window to project to a new sketch.
While in the new sketch if I select " Project Geometry " I am only able to select one line at a time. quite tedious for some of my larger projects.
I can not honestly say that this feature was available in previous releases but it seems to me it was. Am I missing a variable somewhere?

I'm using Inventor 2012, and experiencing some trouble with certain types of projected geometry that I'm using in a sketch associated with a view in an .IDW file - but only when the view involves a break (or breaks).
I'm generating section views to show the layout of hole details at various axial locations along the part. When placing a section line, I can't "pick up" any appropriate locating geometry from the view. So, after creating the view (using just a vertical section line), I edit the sketch that defines the section line. Project some geometry (the edges of the holes, in the attached example), draw some additional geometry constrained to that, then constrain the section line to that. That works fine; if I move the view around, the section lines stay attached to it. This is what is shown in the attached "before break" picture.
When I apply a break to the drawing, though, the section lines don't follow the changing view. They stay right there, as if the view had not been broken at all. This is what's shown in the attached "after break" picture. Move the view around, and they track with it - but always staying the same "real" distance apart from each other. It is as if that projected geometry were completely ignoring the break.
I observe something similar if I start with an IDW view with one or more breaks, then create a sketch associated with the view. If I project geometry, some of it projects where it should, but other geometry projects elsewhere on the page - as if no breaks were present in the view.
The part I've shown here is something I put together as a simplified example of what I'm observing. The part I'm actually trying to detail is more complicated (many more details), and much longer (so breaks are a requirement to put it on paper).

Attached are two parts and an iFeature that I keep in the "Punch" folder and use as a punch. It is common that clearance holes need to turn into slots and vice versa. The centerpoint is the perfect locator for both. The problem is I have not found a good way to place an iFeature slot on a centerpoint as easy as I do an iPunch. This means I have to convert the part to sheet metal and then back again.
Is there an easy way to place a slot, or a similar slot like this with an iFeature? ie as easy as the Hole Feature or iPunch Feature?
The other thing I do is add an axis and plane thought the center points to aid in constraining. If I remember correctly it was not possible to include work geometry in an iFeature (at least with version 10)

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?
