AutoCAD Inventor :: Compare Two Faces
Jan 4, 2013
I would like to compare two faces to see if they are the same face. I have three faces and a hole feature on one of the three faces. I am trying to determine what face the hole is on(top, right, left). I can get the face the hole feature was created on as:
Set oHoleFace = oHoleFeature.PlacementDefinition.Parent.Sketch.PlanarEntity
I can get the three face objects I need to check for the hole on.
Set oTopFace = oExtrudeFeatures.Item(1).Faces.Item(13)
Set oRightFace = oExtrudeFeatures.Item(1).Faces.Item(3)
Set oLeftFace = oExtrudeFeatures.Item(1).Faces.Item(12)
Can I compare faces or do I need to use vectors? I tried comparing the InternalName of the faces but this seems to fail when there is more than 1 hole center within a hole feature.

i got Inventor recently, and i've been working on a model of a longboard just to teach myself how to use the tools in Inventor. right now i'm trying to color areas for the griptape pattern so i drew the 2D pattern and projected it onto the 3D model of the longboard. but when i tried to split the faces of the model along the projected pattern only a few of the projected lines split the faces. for other faces i kept getting these errors:
Create parting line failed Crane.ipt: Errors occurred during update Split11: Could not build this Split The attempted operation did not produce a meaningful result. Try with different inputs.

We had customized styles in Inventor 12 Then installed 13 and had some conflicts using the 12 styles. The person who customized the styles is no longer with us so I dont know what all was changed. Our work stations point to a styles network location so we are all on the same page. I would like to know if there is a way to compare the default styles to the custom files so I know what was changed. Then I would keep a log book of style changes as they occur and update the style of the next release b4 company wide installation. Or perhaps there is a better way??

I have a problem with getting an Inventor model into Revit. It's not the import of the model that's the problem, but the way the model displays in Revit. (It displays fine in AutoCAD, 3ds max etc - just not Revit.)
Here's the part file - it's just a simple box with a couple of split-face features on it to generate a pattern.
If I take the model into Revit, I can only see the pattern if I select the object.
Deselect the object and the pattern vanishes. Here's an unselected/selected screenshot from Revit:

I am trying to put a deck layout decal onto a surface. When selecting the decal command, inventor will only allow me to select the bottom surface and not the top one where I want the decal. is this achievable.
I can do it by flipping the normal and putting on a mirrored image for my decal but that seems like a lot of work
if you create a new part with a cube, sketch onto one of the surfaces and add an image, the decal will only attach to one of the availiable 2 surfaces

how to cut or split more than one face of a surface model in one go. The only way (it seems) is to use the Trim command for every face you need to trim, whereas I want to choose the cutting tool (a plane or face) and then choose a whole lot of faces (by holding CTRL and clicking the faces) and trim them all in one go. Is this possible? I can do this in Fusion, but Fusion is way too slow on my PC compared to Inventor.
I also tried extruding a sketch through the surfaces to cut them, but it doesn't work (Inventor complains that there aren't any solids to cut).

I have seen selection filter and apply selction of faces and edges.
I want to leverage this further. In a part, is it possible to simply drag a window and have inventor select all faces?

I've attached the file (Inventor 2013). The sketch shown is a raised lip I'd like to have around a future opening. I actually want that sketch to wrap all the way around the body, but taper down to 0 in the rear as there are to be hinge plates. This is going to be a grill/smoker and there needs to be a 3/8" raised lip at the future seam of the top and bottom. Shown in the model is just the top portion.

How can I thicken/offset an entire part without having to select all the faces individually? The 'chain select' option is not good enough for selecting all faces/surfaces that meet and form an edge with no fillet.
Is there still no way of doing this in 2012?

In the initial part of the simulation promotional video [URL]....
the internal space of the valve is selected by first selecting faces, then selecting Part Priority and then Isolation, producing the combined total flow volume space. Despite repeating this procedure many times I find I am unable to create and isolate the required volume space. The inner surfaces of the valve are selected but when selecting Part Priority, part of the valve solid part highlights and the selected inner valve surfaces disappear.
I have managed to derived the volume space by subtracting a new derived part, however the example provided in the video suggests the process of defining the air space can be achieved a lot quicker.

I would love for the day that ADSK allows users to assign materials to faces and surfaces at the assembly level. I know this can be done at the part level but this practice has it's flaws when trying to have an accurate BOM and Parts List as well as other "issues" when using that method.
Take a plated part for example. At my company our structure of a plated part would look something like this:
raw material - machined part - plated part. I'm sure it;s the same at many other manufacturing companies.
Typically we will have a material spec sheet for the raw material. We will have an IPT and INV dwg of the machined part file. We then place the machine part (IPT) into an IAM to become the plated part. We do this workflow because if we chance any geometry to the child (machined part) it will update and reflect a tthe parent IAM level (plated part). This also keeps out parts list and BOM structure in-line with our MRP system. So this workflow works great for us.
However there is an issue doing it that way. Inventor doesn't allow to assign materials to faces at the assembly level which seems just wrong to me. I kind of understand why they did that but it sure would be nice to be able to assign materials to faces in IAM files. Yes I know I could acheive this by using Derived Component but then my parts list and BOM structure does not reflect the base part. It only reflects the Derived part in my Parts List. Is there a way I'm missing to alter or change the Parts List to pull info of title, part number, etc of the base part rather than the Derived?
Ideally I'd just love for one day INV to allow material assignment to faces and surfaces in the assembly level. It looks rather strange on our drawings where we do a section view of the top l;evel assembly and see parts that are technically made of brass but look to be made of chrome or zinc plating instead because of how we had to assign material to the entire body of the component at the assembly level.

I've currently written an application for SolidWorks that reads file that geometry in the form of faces (ie. 3 or 4 double values that represent triangular and quadirilateral faces). I am trying to create the same application to work for Autodesk Inventor, but I am having some issues.
First, I am basing my code off from the examples given in the help files. There's a lot of pointers to objects being to get to the Face creation portion, this seems to be slowing my appliation down considerable compared to the SolidWorks counterpart. SolidWorks API has a modelling method called CreatePlanarSurfaceDLL that allows me to provide an array of doubles representing the vertex points in order (x, y, Z) for each point, so the array looks like this for a triangle (P1.X, P1.Y, P1.Z, P2.X, P2.Y, P2.Z, P3.X, P3.Y, P3.Z). Is there anything similar in the Inventor API to simply the process?
Secondly, when using the example, they all have a known "shape" and therefor there are a definied number of vertices, edges, faces, etc. And when adding the faces, the known points / vertices are used. In my case, each face contains information for it's 3 or 4 vertices. I created these using the prescribed methods, but when the final surface body feature is created, and a repair is performed on it, it shows a lot of duplicate edges and vertices. Do I need to take the time and filter out all of the duplicate vertices, and point to a single vertex that may represent a vertext used by up to 3 or 4 faces?

I have an STL (mesh file) file that I converted into DXF file, and then imported into Inventor.
The file contains a surface (meshed) I would like to create a thickness for each face. Since, the number of faces is very large, I cannot do it manually, is there an option/ trick to select them all, or perhaps a different way to create a thickness to the meshed surface.

I'm trying to sweep six circles along 6 3d sketches however I receive the 'The attempted operation had problems trimming and discarding faces. Try again with different outputs.
I have been suffering with the above error message and i am at my wits end. I've tried tracing the the geometry, played dot to dot joining up the points but to no avail. Some sweeps work and others don't.

So it isn't a major issue but I know how measure used to show a blue line when measuring between two faces or points that it measured (by default the closest distance) but ever since installing 2014 I no longer see those lines. Any setting somewhere or if that was just removed completely?

I have created some curved straightening vanes to go inside a large square duct 90 degree elbow. Each vane starts with a 6" long straight section the its follows a fixed radius through 90 degrees. When I "unfold" the part the resulting face becomes two separate faces. When i right click to export as dxf i can only export one face or the other. How can I combine this into a single face to export?

After reading the documentation for IV 2013, I'm not sure if it's possible to create a midplane between parallel faces of two different parts or not. I've tried using the workplane buttons in both the 3D Model and the Assembly tabs with no joy.

When I make a loft, from a 12x12 square to an 8" circle (12" high for the sake of arguement), the corners of the square kind of loft up to the circle where it's corners would be...leaving a sharp break between the planes
Is there a way to make it look like the sheet metal lofted flange appears? So that the corners of the square drift to the quadrants of the circle, making a smooth transition?

I have a multi-body part and want to find the both faces which divide the bodys. The first face I pick with the "SelectSet" command.The second one the program should find on its own.
If I pick a boundary face, it should give an error.
One attempt is to create a point on the first face and use the "LocateUsingPoint". But is there a more elegant way for this task?
(Unfortunately there are little examples of the topic multi-body parts.)

How to get postion of faces of part when place on idw drawing file???
Do we need to use (ThisApplication.MeasureTools.GetMinimumDistance(oTG.CreatePoint2d(0, 0), oFa.PointOnFace)?
If we use that we will get distance but how to get face postion on idw. do we need to use edges?? or lines?

As you can see, there is an entire face of the pipe missing. When I highlight over it (2nd picture) it thinks it is there. This has happened on lots of content center parts. There has been a few issues where this has happened with some of our downloaded user content (in our custom content center) even to the point of disappearing entirely.
This has happened across multiple (identical) machines. However, it doesn't seem to be reproducible on demand.

I quite often import hardware models downloaded form various mfg or supplier websites. McMaster Carr for example provides a great deal of hardware models. While they offer native formats for SW they do not do this for IV (not many places do)
Since the [imported] models often open up with default properties, I change the material to something that closely represents the actual hardware or item. In some cases, there are certain portions of the item that are in reality colored or textured differently and I sometimes want to duplicate that for aesthetics and a more accurate view for people that use my assembly files.
In SW, it was always real easy to select just a face (regardless of whether the surface was part of an entire part, a feature, an imported solid body, etc. I could always change the properties of just a face or slection of faces. Since it was a standard pc of hardware, I had no concern about updates.
I have a part file that contains two imported solid bodies. If I select just a single face and try to change the color of it, it changes the entire part. Not what I want.

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 am trying to use the sheet metal functionality to generate a flat pattern of insulation that is wrapped around a tank. The insulation essentially consists of a rolled cylinder with tabs at the cylinder ends that are to be folded inward to cover the end plates. I can't seem to find a way to make this happen as every time I am able to generate the tabs in the folded model they don't unfold into the flat pattern.
I am using Inventor 2010.

I have a shrinkwrapped file. Now the link is broken from the actual assembly and the orginal assembly is now gone. Now in this shrinkwrapped file, there is a portion that I want to isolate. Is there any way to delete / remove the other parts that i dont need? Extruding, sculpting and delete faces dont work. So far the only thing I can do is add extrusions to the part but not remove.
