AutoCAD Inventor :: Unable To Extrude Sketch Profiles
Mar 23, 2012
I made a sketch. In order to make a hole in the middle of the "triangle", I had to create a tangent circle based on the triangle edges. And then make a new circle (to be the hole I need) and constrain it to the first tangent circle.
This way, if I change the size of the triangle, the hole I need (the inner one) will always stay in the middle of the triangle.
Anyway, when I try to extrude the different profiles of my sketch, something strange happens. As soon as I select the middle circle (not the inner one), 2 of the side outbreak's lose their extrusion.
Second question I have is why did my sketch (except for 2 blue lines) turn from blue to green after fixing loop problems?
(Screenshot’s and sketch file are included.)

Sometimes after I have created a sketch I can not extrude it, sometimes it wont let me click on the profile, other times it will only let me cut away material not add it like I would like. I am sure it has something to do with something fundamental I am doing wrong within the sketch, but I am not sure what.

See attached image file. I can't select just the profile sketch to cut extrude. It only selects the whole face (surface). I have this issue on (2) different workstations and on various parts along the way.

Inventor 2013: It seems that in this version, selecting profiles for extrusion is buggy. I have many times now (sketches based on either projected geometry, new sketches with all rectangles drawn, all lines, or rectangle with offset. ) been unable to choose the profile I wish. It seems there is some sort of Island detection (or lack of it) See attached. I wish to extrude the center rectangle only, but can not...
Every time I end up with either retracing the outlines or create another sketch on top of the complete extrusion and then subtract.

I know my subject is somewhat mis-named, because I gather that you cannot really extrude from a 3D sketch, however I am looking for a way to accomplish what extruding a cut from a 3D sketch would accomplish.
The problem is this: I have a simple 2D sketch that I've projected onto a curved surface (imagine a square projected onto the outside of a hollow cylinder). Now that I have a 3D sketch on the surface of the cylinder, I want to use that sketch as a "cookie cutter" through one wall of the cylinder.
If I were to simply extrude the cut from the 2D sketch, the "cookie" is wider at the edges than at the center. I want the cut to be perpendicular to the projected 3D sketch at all points.
I've attached a simple example that illustrates my problem.

I'm using a template file (part with just a drawing in it) for the basis of a few parts.
In one of these parts I use the template sketch for an extrude. After that I would like to use it again for some other extrude.
But I can not reference the drawing again. Normally I can 'share'a sketch. But somehow a sketch from a template file can not be shared. How can I use the template sketch for a second extrude?

I am trying to extrude sketch 3 to the Extrusion 1 but keep getting Error....is this the wrong way to create?
Also the Extrusion 2 cut out for centre hole does not seem completely round.....
Could this part be made using better techniques.....how can i create this part with better steps

I'm just wondering is there a possibility to select all closed profiles from a sketch to make an extrusion or revolve with a shortkey instead doing that manually with the mouse for each profile? Something like CTRL+A

I am looking for the best way to place multiple columns in a single part file (as independant parts). I want to do this to accurately represent a steel structure that we purchase with a single part number. The structure is purchased and not modified so I figured a single part file would be better than an assembly file with multiple parts.
I thought the best way would be to extrude a 2D wide flange beam profile. However I would like to just pick the profile from a database (content center?) instead of going through the hassle of sketching each profile manually.

I am using inventor 2011 to make an assembly, and No matter wether I sketch off a face or a plane, I cannot get get my sketches to extrude, inventor wants to make cuts when there is nothing to cut. Not sure what I am doing wrong, becasue when I try doing the same thing on a new part it works just fine.

I'm trying to extrude a logo through a shape I have already created, however, "the attempted operation did not produce meaningful intersection edges from the face-face intersection. Try with different outputs."
I'm using Autodesk Inventor 2014.

This is a problem I've had on 7 pc's:
All of the pc's are I7's 8gig Windows 7
The problem is, while making a sketch and trying to hatch it, it's locks up the system. Completely using up all of the resources to the point I have to unplug the pc/hot boot it.
This has been happening on both Inventor 2012 and 2011. (doesn't matter which version of Inventor .. Suite/Prof, Ultimate etc)
I'm thinking it has to be a Windows update that is messing it up, as it worked in the past.

I have this dwg that i've imported into a part sketch. All except one layer won't come it. So i have made a dwg with only the culprit layer, see attached. Why nothing gets imported into a inventor 2012 sketch.
BTW all layer from my main dwg file gets imported into on single layer even tho i'm not using the option to do that. It is not a big deal compared to that layer not being imported.
try to import it and let me know if it works, my autocad and inventor are patched SP1

I have three sketches. Two are 2D sketches and the third is a 3D sketch created by the intersection of two surfaces created from the previous two 2D sketches. The order of the browser is as follows:
Sketch1
Sketch2
Revolution (surface)
Extrusion (surface)
3D Sketch 1
When I go back to edit Sketch 2, Sketch 1 is always showing...regardless of whether or not I turn on/off visibility. The visibility toggle has no effect. Sketch 2 has no projected geometry from Sketch 1.

I have draw in DWG the front view of a ship's frame. I've closed the loop in inventor and extruded the object but I am unable to sketch on most of the surface to complete the side view..??
I can only sketch on one section the upper and lower sections it won't allow me too.
The top should be offset to the right but I am unable to draw the sketch onto the fame.

This is the first I've noticed this, but a sketch in an assembly does not allow to show the dimensions as an expression? In a .ipt sketch you can right click and the pop-up menu has an option to show the dimensions in different forms. I do not get this in an assembly sketch.
I do not know if this is me or not. It's just curious that it does not do that.

I have a sketch reference that is giving a cross part failure error. I am unable to select the reference in the browser so I cant delete it or update it.
How to get rid of it. Deleting the sketch and starting again will be a disaster.
Using 2011SP2 XP64.

When I use a tool such as 'move'/'select base point' in the sketch environment, I used to be able to select line midpoints.
Is this no longer possible? My constraint options seem to be fine.

I've just started working on a frame generator assembly I was modelling earlier this year; I can't seem to modify the base 3D sketch. The feature which looks like the original 3D sketch is now called the "Reference Skeleton" and I am unable to modify it at all.
I am working on a copy of the original part as I "save as" the whole master assembly when I was last working on the model. I don't know if this would have effected anything.

I am not able to extrude closed polyline shapes. I get the following message:
Cannot create solid from open curve.
Cannot sweep or extrude non-planar objects.
Unable to extrude the selected object.
Other folks have opened my drawing – some can extrude, some get the same or similar message. I’ve tried re-building the shapes to extrude. It worked with one thing this morning and now it won’t extrude again.

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
