View 7 Replies View RelatedI'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
View 2 Replies View RelatedI 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 want to query the depth of an extrude feature in a model from a drawing file - I've got access to the feature from the drawing file, but I'm struggling to find the correct method to query the extrude depth.
I can see I can get Faces / StartFaces / EndFaces from which I could do some evaluation on - however, StartFaces.Count is 0 (not sure why) EndFaces.Count is 1 (seems logical) and Faces.Count is 9 on a simple rectangular extrusion of depth 10mm.
In reality the extrusion could be any shape, any depth and either a set depth or through all.
Am I on the right tracks with evaluating the Faces collections? Or is there an easier way to get the depth ?
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.
View 9 Replies View RelatedI'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?
How to check the direction of an existing extrude feature
kPositiveExtentDirection
kNegativeExtentDirection
kSymmetricExtentDirection
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.)
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

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.

View 1 Replies View RelatedI'm a new 2009 Inventor user (use mostly Solidworks for other jobs) and how to make the model update after I modify a feature sketch (e.g. I only add one more circle/hole to a sketch used for a somple extrusion, but the extra hole doesn't appear on the model). Tried all update-related commands but no luck so far. If I delete the feature and recreate it again everything works fine, but I stuff up all other features and mates that use the reference geometry...
View 2 Replies View RelatedI have a simple ipt file (attached)
It is a simple rectangular plate with 13 holes through on a pitch circle.
I have used a "circle" to construct the "Pitch Circle" and a "line" to construct the top dead centre of the circle.
I have then added a circle to use as a hole feature and used the circular pattern to make the holes equi-spaced around the circle.
This circle is then extruded "Through All".
My question is, How can I eliminate the construction "Circles" and "Lines" from the following code, only allowing sketch entites that are directly associated to an extruded feature to be accepted?
Public Function WriteDxfSketchEntities(Doc As PartDocument, sketch As PlanarSketch) As Boolean
Dim partCompDef As PartComponentDefinition

I just want to notice the Autodesk guys that when editing a hole feature in an assembly, then the sketch is hidden so that is not possible to pick more centerpoints. I noticed this when working with a sheet metal part, I don't know if its the same with a regular part.

I need to disable the "Set sketch scale by the first dimension" feature.
The feature is nice under normal circumstances, but in my case i need to insert a dxf sketch and then draw around it in inventor. When i start to dimensioning the sketch then it scales the inserted part.
That aint so good.
is there a way to use vb to add closed sketch loops to an existing feature?
I am trying to create a parametric template for a fan guard assembly, complete with drawings.
I am using an arrangement of circles defined using some linear sketch patterns as the cross-section of a revolved feature. Using ilogic/vb, I want to automate the number and spacing of items in the linear pattern, and then update the loops selected for the revolved feature.
I have found code on this forum (courtesy of Curtis Waguespack) that I can use to select all closed loops and create a feature. I can apply this code to create a NEW revolved feature, but I haven't been able to figure out how to use it to UPDATE an existing feature.
I need the feature to UPDATE rather than create new to maintain links in my assemblies and drawings.
Is it possible to fill an area with hatch patterns in a feature sketch (ipt sketch), not in idw sketch?
I want to show a safety screen (wire mesh) in a 3D model, in order to reduce the file size, I do not want to do solid wire mesh in the model, but the sketch only. I was drawing one by one line and make a hatch cross lines in the sketch, it took me lots of time to draw these lines.
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 am trying to create a part that has a spherical feature. The spherical feature is "sliced" on the front and back to create a flat surface (see Compound Rest Handle Isometric image). Should I use workplanes to slice the sphere? What is an efficient process the slice the sphere. See Compound Rest Handle Front and Compound Rest Handle Back images and compare to the final result in the Compound Rest Handle Isometric image).

View 3 Replies View RelatedI created a 12-sided polygon shape in the sketch mode. I created one line, fully constrained it and then used the circular pattern to finish the shape. Why can't I extrude the shape?
I have attached the file. It's a pretty basic shape. I don't understand why it wouldn't work...
creating a named sketch block (in an ipt) containing entities that I have created in the same sub? I'm doing this from Excel, in Inventor 2010.
What I have:

note that i've also taken a shortcut with the arcs, and the circle. I did try to create them using the same naming convention as the lines, but... I failed to implement it successfully.Also, I can not quite figure out how to constrain all the start/end points together.
I created a 2D planar sketch, now I need to create a 3D sketch and Helical curves, but as I enter into the 3D sketch mode, I cannot perform any functions, all my tool bar options are grayed out?
I am running 2014 Pro Design Suite.
I created an assembly of parts and then converted my assembly to a weldment. I then realized that I need to create a sketch and make an edit to my assembly. The sketch command is greyed out however. I did some trouble shooting and realized that once I converted it, it no longer allows me to make edits. Is there anyway I can get around this? do I now have to re-create the entire assembly to make this edit at the assembly level? If so this would really suck since it is a rather large assembly. I see saving as a new IAM doesn't work as well.
View 5 Replies View RelatedI 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 am trying to create a sketch on a face for an extrusion. The sketch has a text box. I am having trouble excluding the text in a sketch otherwise all the closed geometries of the text get extruded.
I created an objectCollection and excluded the TextBox objects. Still not working.
I am not sure exactly why this is a limited feature of Inventor 2011 but when you want to select a sketch to create a boundary patch you have to select each part of the sketch in sequence. It's a pretty laborious task. I am looking to a way to automate this using i logic.
View 5 Replies View RelatedIn 5.3 I can create reference dimensions in sketch mode to my hearts content. They became very valuable as I would use them to determine placement of multiple features. Now, in IV 7, I have alot of trouble creating reference dimensions from adjacent features on the same surface. I have to change the way I'm working now and it has stumped me on a few occasions. is there a "new" feature I need to enable or is this the cost of progress?
