AutoCAD Inventor :: Controlling Sketch X And Y Axis?
Jan 8, 2013
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.

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.

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 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 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.

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 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 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 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.

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.

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++; }

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 have an assembly drawing which requires a break in the drawing view due to its height. The drawing view scales accoring to the change in height (so it remains the same physical height on the drawing), however I need to be able to increase/decrease the height (or value) of the break linearly to the height of the assembly.
I had a look at the ilogic 'break sample' and tried to adapt it to my needs, however, i couldnt get it working. I am using Inventor 2012.

1) I have assembly containing pipe and a flange. I want flange size to correspond pipe size. In other words, when parametrically change pipe size, flange size to be updated automatically. ( do i need to have two parts - pipe and flange, or it can be one assembly without need to create parts?)
2) Is it possible to control type of flange (slip-on, weld-neck.. etc) by parameters or need to make different assemblies for different flange type?
3) Then when flange and pipe sizes are updated would like to make overall length of that assembly whole number (since hub length changes with the flange size). how to round that overall length to integer?

I've been running into issues in IV 2010 with the shading where I need to show a part in a perspective view on my IDWs and depending on the angle I rotate to the majority of the part is shown in shadow. It's frustrating because I need to show a feature in that particular orientation, but the whole part looks dark.
Especially when I am showing left and right mirrored parts. One side always seems to end up dark. FYI I almost never show the material as a texture map in my part drawings so I use white as the color default because I am simply trying to get across the shape of the part in a shaded 3D view. These don't really serve as renderings to me per say. Is there any way to control the light source direction for custom views in terms of shading? Could I make it more of an ambient light or similar to the Global Light Style in Inventor Studio.

I have a browser display issue that occurrs sometimes when imported parts are inserted into an assembly model. Before dropping some imported parts into my assembly model I changed the filename to something corresponding to our part numbering system. When the part is dropped into the model, the name of the instance displayed in the assembly browser is the same as that originally used by the originator of the model.
I know I can change the name in the browser by editing the name field in the occurrance tab; but I'd need to do this for each instance. What iproperty field (or other property field) should I edit at the part level so that the revised part name is used in the assembly browser whenever that part is inserted into an assembly?

I have made a family of weldments. I am having trouble controlling the visibility of the weld symbols when I place one of these members. On some members the welds are shown and on others they are not. I know that I can turn off all the welds (View>Object Visibility> Weld Symbols) but there are other weld symbols in the assembly that I need/want to leave visible. In the image below all three weldments have the same welds, but the weld symbol of only the one is shown when I place it in an iam.
In each member of the iassembly, I have unchecked the visibility under the Welds node, but some are still visible when i place them, so that must not be controlling it. Sure would be good if visibility of welds were controlled by view representation.

I have common parts (custom frame member) that I use repeatedly in assemblies that I don't need to show in a parts list. Is there a way to control this so they don't show up in a parts list? Currently I go into the parts list and turn them off before exporting the list.

Many times I see that these types of irregular shapes which comprise of spline curve are created with very less or no dimensions, so I want to know how this spline curve was created and can be controlled, if I want to create it in an exact manner what dimension I should use ?

I am setting up a family of parts that consist of a round disc with a fixed OD and a circular pattern of notches cut into the OD. The notches must go to a certain depth from the center, so those parameters are set. My problem is that I need to control the amount of material left between the notches, along the OD, after the pattern is done. Given the fixed parameters of the major OD, minor OD (3.5" in this case) and number of notches, the only way to control the amount of material between notches is to change the angle. When I set up the sketch to do the notches, I can only get a fully constrained sketch if I assign a specific angle to the notch. I need to be able to set it up so that the angle of the notch varies so the end result is a specifc amount of material left after the circular patter is completed.
In the attached PDF, I show what I have done so far. In this case the OD of the part is 4" and the diameter of the notch at it's closest to the center is 3.5". So basically, I end up with a driven parameter of 0.443. If I assign this value the parameter of d14, I need to make it equal to a ratio of another parameter (let's call it d15) so that d14 = d15*2.. This can only be accomplished by changing the angle.
In my family, the major OD and minor OD remain the same, but the angle must change to retain a specific amount of material between the notches when the number of notches is increased or decreased.
Is there an iLogic rule I can write to control this?

I have a part and I need to scale it in the Z-axis only. It is impossible for me to rework the base geometry directly.
I have made some attempts to figure out how to do this on my own but all have failed:Thicken/OffsetCopy Object + Move Bodies + Combine (wouldn’t let me create a solid with Copy Object)Rectangular Pattern + Combine (works but not the desired result. adds a constant offset to the part, not % based, humongous model size)Derived component (uniform scaling only, prefer to modify the original file for file structure reasons)
