AutoCAD Inventor :: Add Closed Sketch Loops To Existing Feature?

Nov 26, 2012

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.

AutoCAD Inventor :: Getting Closed Loops From Polylines In DWG Files

Feb 26, 2012

I am trying to import a complex curve from autocad lt (in my case an airfoil), to create parts.  I have drawn the curve in autocad lt as a polyline.  Autocad lt treats the curve as a single object, and seems to understand it as a closed loop. 

When I import the curve into Inventor lt, Inventor treats the curve as a series of unconnected line segments.  What can I do in either Autocad lt or Inventor lt to get Inventor to treat the curve as a single object, so that I can then extrude it?

AutoCAD Inventor :: Ensuring That Sketches Are Closed Loops?

Mar 7, 2013

I am making some fairly free form sketches using lots of 3-point arcs that ultimately need to be closed loops so that I can extrude them. Although I have always been letting one arc snap to another at the end of the process I seem to have trouble closing the loop. It does not seem very apparent how to find the points that are not properly closed and I wind up struggling with the Close Loop function. Is there an easy way to tell where the problems are in a profile? I have tried showing all constraints, but that doesn't necessarily give me the clues I need.

AutoCAD Inventor :: Shared Sketch Generates Sketch Doctor Error - Feature Suppressed

Sep 21, 2011

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

AutoCAD Inventor :: Stable Closed Sketch Profile Creation

Sep 16, 2013

Which one of these methods insures that there will be no error, or bug on closing the sketch profile in all the future versions of inventor?  One is simpler than the other (no line on top of line, no need to make extra construction line). I'm fine either way, i just want to know which one is the SAFEST FOR LONG TERM PART FILE STABILITY.

AutoCAD Inventor :: Reattaching Existing Dimension In Sketch

May 15, 2013

I have a part.I use some Parameters of this part as linked to other parts.Once I change any parameter used as linked the other parts will follow it automatically.So I have drive and driven parts.

Now for some reason I need to change some geometry in my drive part in the way my drive dimension must be reattached to other geometry points.

I cannot delete and create the new dimension even with the same name since all my driven parts will lose this linked parameter in either way and this parameter becomes static (Reference Parameter).

I wish I can preserve the existing dimension (parameter) and reattach it to other geometry.

AutoCAD Inventor :: Turn Existing Sketch Into A Symbol?

Jun 2, 2012

ACA2011My dimensions seem to be fickle with regard to snaping. I've got my OSNAPs on, and I can't snap to a structural beam above, nor can I snap to a window sill. I can dim to the mid point of the window sill by using .x & .y filters, and can only snap to the axis line on a beam. Is there a toggle somewhere?

AutoCAD Inventor :: Model Update After Modify Feature Sketch

Feb 27, 2012

I'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...

AutoCAD Inventor :: Only Allow Sketch Entities If Directly Associated To Extruded Feature

Aug 12, 2012

I 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

[Code].....

AutoCAD Inventor :: Sketch Gone When Editing Hole Feature In Assembly

Jan 6, 2012

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.

AutoCAD Inventor :: How To Use Existing Sketch While Making New Part (model)

Aug 12, 2013

I have made a part - a motor that has four holes.

Now I'm trying to make another part, which will be aluminium plate that needs to have holes in exactly same points as the motor. My assembly containts both that parts.

What I'm trying to do is to reference in sketch a point that comes from different part (motor).

I could do it by hand, make it look that the holes are on top of each other but then there will be an error which doesn't seem professional.

In some tutorial on yt I have only found that using points one can reference the holes more easily, but it didn't show how.

AutoCAD Inventor :: Fill Area With Hatch Patterns In Feature Sketch?

Feb 4, 2013

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.

AutoCAD Inventor :: Sketch Orientation / Can't Dimension To Any Existing Vertices Or Edges

Feb 16, 2009

Why the heck does Inventor arbitrarily orient sketches as it sees fit? I often create my first sketch on the right (YZ) plane and Inventor, stupidly turns the sketch where "RIGHT" in the viewcube reads from top to bottom.

I know all the things to do to AFTER this happens, but it shouldn't happen in the first place. If I turn my sketch so that up is up, like it should be, I then have to remember that vertical is horizontal, which is now vertical. I can't change the sketch coordinate system. It's the first sketch and there is nothing to align it to.

How to prevent the above example from occurring in the first place.

This, and the fact that I can't dimension to any existing vertices or edges without projecting them first, really make me hate using Inventor sometimes. To me, these are huge problems, neither of which Solidworks has. At worst, both of these behaviors should be configurable.

AutoCAD Civil 3D :: Break A Closed Feature Line

Jul 28, 2011

I often use feature lines for parking lots and ponds.  They're great when they work, but they drive me NUTS when they don't - which is a lot of the time.  For parking lots and ponds, my feature lines usually close back on themselves.  That's when I have trouble breaking the feature line.  When I use BREAKFEATURE, I choose two points and this should, in theory, leave a gap in the feature line between those two points.  That's not what happens.  I end up with a huge gap between the first point I picked and a vertex point 5 or 6 vertices away.  It doesn't matter where I pick the breaking points.

I've also tried TRIMFEATURES.  I draw lines across the feature line where I would have chosen the breaking points.  But the portion that I want to remove is the portion that always remains.  It doesn't matter where I select the feature line to be trimmed (inside or outside of the cutting edges).

I think there may something wrong with the feature line itself.  Sometimes, if I erase the original and draw a new one, it will trim just fine.  But that's such a headache, and it doesn't always work.  If I knew what was causing the feature lines to go squirrely,  I would aviod it.  Unfortunately, it seems like breathing the wrong way can screw up a feature line.

AutoCAD Inventor :: Self Intersecting Paths Or Loops Are Invalid For Operation?

Mar 9, 2012

In regards to sweeping, what does the title of the post mean (self intersecting paths or loops are invalid for this operation). I have a 3D sketch consisting of 1 straight line, one spline with 4 points dictated by 'points' and an arc. All have tangential constrains to each other and I am looking to sweep a circle along this path to create a bent wire. I don't have anypictures or files as it is a stand alone computer at the moment.

AutoCAD Inventor :: Copy Part Sketch Into Drawing Sketch

Sep 20, 2012

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.

AutoCAD Inventor :: Converting 3D Sketch To 2D Sketch From IGS File Using Wires?

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
