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.

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?

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.

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.

It happens often that a sketch has redundand points or open loops.
I don't want to run the sketch doctor to clean it up every sketch I create.
In the attached avi you can see the few steps that I use to create a sketch. I don't understand why at the end it has problems.

Why does this code fragment not work? (Within an active part sketch, with some sketched geometry.)
I'm just trying to close the loops to have valid extrusion profiles.
Dim iCounter As Integer
Dim icounter2 As Integer
Dim oSPoint1 As SketchPoint
Dim oSPoint2 As SketchPoint
Dim xVal1 As Double
[Code]....

I am trying to modify a hoop instead of having a half circle, i half to cut the hoop short and add a flange, instead of starting over, is there a command I can use that I can create a flange and join the hoop and flange at the intersect..... the hoop was made using the fold feature...

is there a command or workflow to split all intersecting surfaces? currently we build surface models and split manually or open in autocad, explode, overkill, breakall, then export the lines for rebuilding in an FE package.
Ideally we would like to export straight from inventor with one hit i would like to do the 5 splits below the EOP marker automatically

I have a rectangular chute, tapering in width and height, and intersecting, at an angle, with a round duct. I can't seem to find a way to determine the cut-out in the round duct.
Because the chute tapers projecting the size onto a flat plane to then project onto the round duct doesn't work.

I'm trying to find the intersecting points of a part that connects to the outside surface of a cylinder shaped part.
What is the best way to go about this? I have attached some images that hopefully illustrate my problem.

I want to create a solid using VB and loft definition.
I creat each time different planes that have a constant distance in x dimension and a steady rotation each time φ (deg).
On each each plane i sketch the same profile and that is happened for 360 deg.
The problem is that Loft is not made because a line of the profile must follow a line tragectory and all other points must follow a circular tragectory. Also, there is a problem from 180 deg to 360 because there is intersection of profiles.
The result must be a solid similar to snail shell but all the same solid, as a cylindar whith a half sphere in the bottom.

I need to trim a part that intersects with many other parts in several different sub-assemblies - on an angle.
**Attached is an image of my problem.
Split tool is disabled. It is only usable once I drill down into the assembly/part - it will not select the other cutting objects higher up the browser stack.They become ghosted.
What I need is a tool that projects intersection lines. Does Inventor have something like this? Standard projection lines on the part is not working because the cutting objects are not 90 degrees angled to the part to be cut.
This may be easy,.. I am just not seeing a way to do this with out a bunch of work-a-rounds.

We build ASME chambers that have ports and tubes that intersect at various angles. When these tubes intersect at a standard angle, center on I have no problem creating the sheet metal layouts for the tubes. The attached PDF shows one intersecting at two differnet angles, off axis.
he sheet metal layout fo the tube part? I have modeled it pretty well, I just can't figure unfolding the tube portion. The head is a buy out item, we have that.
I have to ascertain two things ultimately, the hole size/layout (easy) and the tube (stumped).

I am working on Sweeping three helix profiles around a cylinder to create a screw thread. When I sweep the profile, Inventor gives me the error messages:
"The attempted operation would create a self-intersecting surfaces. Try with different inputs".
or
"The attempted operation did not produce meaningful intersection edges from the face-face intersection. Try with different inputs".
However, this is exactly what I need to create the helix profile I require and eventually increase the size of the Extrusion Sweep profile to 80mm. When I increase the sweep profile to 80mm I get the same error message about the self intersecting surfaces.

I want to draw operation drawings, I think, ı must do this like that; I must draw one ipt, and later I must draw drawings from this ipt, and idw's
1.drawing (operation); rectangular prism,
2.drawing (operation); rectangular prism and rectangular cutting,
3.drawing (operation); rectangular prism, rectangular cutting and hole,
4.drawing (operation); rectangular prism, rectangular cutting, hole and hexagon cutting,
when I change dimensions of rectangular prism, all four operation drawings must change, so I can't change location of end of part in idw's browser, but I can change location of end of part in ipt's browser, I want to change location of end of part in idw's browser, can I do this? or alternative solution...
I don't want to make, four ipt for each operations... I added a picture...

I keep getting this message when opening an assembly;
Internal error in persistence operation (Can't load segment PmResultSegment via a RSeRef when loading segment PmDCSegment)
The solution is to find the corrupted part and restore it.
My problem is that the assembly (and 5 subassemblies) consists of over 150 parts, which is way to many to just start recreating parts at random...
Is there a way to pin-point which parts ruins my model ?

I am using Cable and Harness (Autodesk Inventor 2012 64 bit on Win7 64bit) and when trying to create the segment I only get the error message "The sweep operation failed for the harness segment Segment1 Adjust the segment geometry and try again". It does not matter what data for diameter and bend radius I am using under "Harness properties", it never works. When checking the "Bend radius" for violation it says nothing. I am attaching the files.

I'm trying to create a model of a Golf club head. I need it to be hollow but I am unable to do this using the shell operation or by creating a surface and thickening the faces. I created the geometry by lofting a series of sketches. I think the nature of the geometry may be causing the problem.

After a slice operation i have to make a sketch and complete lines.
For example, if i slice in the middle of a threaded hole, in the slice i don't see the thread lines, i just see as if there was a hole.

I derived in a part and I am trying to use a sketch from it in my new part.
I am trying to revolve my sketch and when I do I get this error.
I am using a English version, and I cant read chinese at all. Design doctor shows no errors, but this will not revolve. Tried Extruding and get the same error. When I try to revolve, it shows a preview of my part correctly, but when I click apply in the revolve dialog, that is when I get this error.
The files are attached and here is a video of my steps. In the zip file, the -M8.ipt needs the EOF marker moved all the way to the bottom.

i get an error message telling (invalid thread data table. Please check Thread.xls file.i tried to reinstall the windows and the autodesk inventor but the error keep appearing.
1.my os is windows xp sv2 32 bit
2. inventor version is 2011 32 bit i also had the same problem with 2010
3. i tried to reinstall without any antivirus on my pc but i still have the same problem
4. what's a UAC?
5. yes i've office 2007 installed & i had tried with office 2003 but also the same problem.
1 the first time i used, i made the bolted connection once, but at the second time i kept having this issue.
2 my last trial was installing a freh copy of the windows then install office and the inventor only but nothing changed
3 i tried to install the inventor on another pc but i also had the same issue
4 i searched the c drive for the file THREAD.xls, and i found three of it and i guess they are fine.

I have inventor 2012 and I´m having trouble doing a cut boolean operation to two solids. One is a revolved elipse, so it´s a kind of egg, and the other one is an extruded rectangle.
I want to cut the egg in the rectangular solid, so I can obtain a rectangular solid with an empty egg space inside. I tried to use the "derived" command, so I derived the egg from the rectangular solid, and used the combine command, but with no success. Right now I have two separated solids on the same file (the egg and the extruded rectangle).

I am having an issue with saving our own dwg file in inventor 2014 & 2014.
When I open a new one of our dwg template files and try to say I get an error that says
"the current operation requires data from document 'xxx' but it cannot be found"
This doesnt happen when trying to save an inventor dwg template file and it has only happened since releases 2013 & 2014. If I open one of our files that was created before release 2013 I can save these with no problem.
I was hoping the issue would resolve itself when upgrading to 2014, but It hasnt, so it must be in a setting that I migrated across.
We have other users using 2013 and are not experiencing the same problem. In fact if they save one of our template files on their machine I am then able to open and save it on my machine!
