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.
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.
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 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?
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.
I am a beginner when a extrude a feature and select a part surface for new sketch now i want is to offset that surface but i can,t there is + sign with mouse icon and something like fully constrained is written in down the window.
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'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'm making a tube that is connected on another tube. I did this by skeleton modeling, for my tube extrusion i used Extrude To surface.
Is there any way to get the length of that extrude?
I know its possible to get the sweep length like this. Is there a way to get the extrude length as well?
'Set a reference to the active part document

I cannot extrude a 2D shape that is drawn by lines.It appears to be linked but is not .I can see the problem saying not a closed loop or a constraint but don't know how to fix it.
So I started on this project recently and was not the original modeler. This section of pipe has some problems where I'm guessing a sweep went wrong. I've tried everything I know to do to try to fix this section but haven't had any luck.
- This model has no tree and is shown as one soild "base"
- I tried to extrude cut the bad section
- I tried spliting the bad section
- I exported the file as an IGES and then tried to remove bad section
I'm sure there are some other round about ways I tried that I can't think of but in the end nothing has worked.
I'm using the extrude tool so that the rectangle that I'm extruding (downwards) will taper (and become thinner at the bottom). However, when I do this, even as a fraction (.01) it seems to get bigger at the bottom. How do I make it thinner at the bottom, not bigger?
I was watching on of the "Sales" videos on Autodesk.com. I saw them extruding a part surface to another surface of an imported part. I have a need to do this. When I try to extrude my part, I cant pick the surface that I need it to go to.
The video I am watching is here. Its titled "Native Translators". They show the surface being extruded at about the 0:53 mark.
The problem that I have is while working in the assembly, I double click on my part to edit it in the assembly. Next I chose Extrude and "To Next", but I am unable to pick the surface I need it to go to. The surface is in another part that is in the assembly. The part I am trying to extrude is adaptive, like in the video.
I did notice that in the video, when they pick the "to Next", the add/cut/intersect is greyed out.
Right now I am trying to model a concrete embed plate. The design calls for 1/2" round steel embeds at the contour of the line in the attached image. What is the best way to extrude this line into a 1/2" DIA dowel? I have tried the revolve command and sweep command without any luck... I know the sweep command would probably work the best but I can't seem to draw a 1/2" dia circle perpendicular to the line.
I'm fairly new to the world of CAD, and I was just working on a phone case for my friend when I tried to extrude geometry text, but couldn't because the OK and Apply options were greyed out. I tried embossing and making a hole, but they were greyed out for them too. I tried messing with the settings to see if I could fix it, but I still couldn't. I'm really confused right now, I remember doing something similar for a case I made for myself.?
I am creating a fan wheel (see attached). The fan blade needs to be extruded to the inside surface of a 2 piece cone assembly. To make it even more difficult, the inner portion of the blade needs to be cut at an angle so that the extrusion ends at the cones. See attached pdf reference sketch. The result for the flat pattern blade edge should be two parabolic curves.
