AutoCAD Inventor :: Compound Miter On A Tube

Sep 20, 2012

I have several parts to get cut for one of our customers.

The provided the pdf I have attached, and I need to create and .ipt so we can cut it on our tube laser.

This is getting the better of me on how I would put my work planes in order to get the correct angles.

How to accomplish this?

AutoCad 3D :: Creating Tube Miter Correctly

Mar 9, 2012

To draw the cope end I subtract one tube from the other, this creates a taper from wall thickness t at the intersection of the inner tube face to zero at the intersection of the outer wall face. This loss of wall thickness is not ideal. To get rid of this less than full thickness material I create a slicing plane through intersection of non-cut tube 1 and the inner wall of the tube to be cut, I establish this point by drawing a 2D cross section.

I realize this a bit of a hack and it never works out spot on as the slicing plan never seems to match exactly the intersection point of the 3D tube inner wall.

I have tried to get a work around. i.e. :

- drawing a tube inner radius only subtracting from that then shelling-this only re creates the taper.

-offsetting the intersection edge of the inner wall and trying to project onto outer at 90deg-this does not offset correctly due to the complex geometry.


1. How to create a mitre maintaining full wall thickness. 90 degree intersections.
2. How to create a mitre maintaining full wall thickness. Non 90 degree intersections.
3. How to create a mitre maintaining full wall thickness. Tubes angled in 2 planes i.e. : for triangular space truss.
4. How to create a mitre maintaining full wall thickness. Tubes angled in 2 planes centers lines not coincident ie internal members offset to enable 2/3 to meet at same node.
5. How to deal with the above when using non round tubes.

AutoCAD Inventor :: Calculating Tube Length (not Tube And Piping)?

Mar 16, 2013

I have a question about calculating the maximum tube length. Why do i ask this, because you can just measure it on drawing?

I'm building a parametric model for building simple storage tanks, and the goal is to get a complete BOM out of the model without any difficulties.

I have 4 possibilities of tube positioning on the tank. (see image)

1. A tube that stands in the center of the axis of the main tank.

2. A tube that stands in the center of the axis of the main tank, but under an angle

3. A tube that doesn't stand in the center of the axis of the main tank.

4. A tube that doesn't stand in the center of the axis of the main tank, but under an angle

These 4 possibilities can be flush with the inside of the tank or not.

Is there a easy way to determinate the longest point from the front of the tube? This longest measurement will be the length i need to get into my description for the BOM.

AutoCAD Inventor :: Repair Tube Constraints In Tube And Pipe?

May 27, 2013

How do I repair a tubing constraint?

I use tubing in inventor, I always attached tube to whatever fittings I am using and everything is fine but if something gets moved that the end of the tube loses its contraint I'm ready to jump off a cliff!

Is there any way to get the end of the 3D sketch contrained to the fitting again?

Up until now I have always had to deleted the route and started over. Inventor Pro 2014

AutoCAD Inventor :: Miter CC Custom Parts

May 1, 2013

I am looking for a way to miter two pieces of rectangular hollow section.

I have placed the parts from the content center as custom parts, now I am looking for a way to perform a miter on the them where they intersect.

I am aware I can perform the miter if the sections had been created through frame generator but I was wondering if miter could be used outside the fg environment.

AutoCAD Inventor :: Maintaining Direction Of A Miter Bisecting Two Lines

May 15, 2012

I am trying to miter the joints in an assembly being used for iCopy. Currently there is a driver sketch which has lines bisecting each corner at 45 degrees. However, what happens is that when the top line of the sketch is dragged across the bottom line of the sketch or the left line is dragged across the right so that the rectangle inverts itself, the line no longer bisects the angle. See the attached pictures for details.

This sketch shown is a master sketch used to drive part length and end details in an assembly. The blue lines are extruded into surfaces which define the parts using a "Between two planes" extrusion.

The sketch is unconstrained in four ways: overall width, overall height, vertical and horizontal movement. This is done to accomodate its use in as a flexible assembly in an iCopy command. What happens is that when the user applies the iCopy points from the wrong side of a sketch plane in the parent assembly, the sketch flips itself and resizes the assembly but the miters are inverted.

AutoCAD Inventor :: Emboss Patterns On Compound Surfaces

Sep 24, 2013

I'm stuck on a few different emboss cases. The following examples are just dumbed-down models to learn from.  If it matters - I'm actually embossing patterns on more complicated parts - not text on primitive shapes.

Case 1:  Emboss across several surfaces.  Please see attached file "Wrap Emboss 1".  I can wrap to a face - but not all three faces on the solid that I want my "TEST TEST TEST" message to span across.  My embossed text goes off into space - it doesn't wrap around the edge of the solid as desired. 

Case 2: Emboss text (or some other arbitrary shape) onto a single (but compound) surface.  Please see file "Compound Emboss 2".  If the curvature of the part isn't significant - there are a few ways to fake/trick out the model to get a passable result.  BUT - when the curvature of the surface is significant relative to size of the text/pattern to be embossed - I haven't yet found a solution that doesn't wildly distort the embossed feature.  As the surface of the part is compound - I can't use the "Wrap to Face" option without an error.  The resulting embossed feature is unacceptable.

AutoCAD Inventor :: Dimensioning Compound Angles Using Current View?

I'm having problems getting Inventor to dimension using the current view option on an assembly.  I ungrounded the assembly and constrained it to the angled work planes that I needed so I have to use the current view option, but when I try to dimension to the intersection of the angles, it won't give me a dimension.I'm using Inventor 2011.

AutoCAD Inventor :: How To Show A Hole Drilled At Compound Angle

Sep 6, 2013

In the attached part, I am trying to show a hole drilled at a compound angle. I have attached a pic of what the part is supposed to look like. I am having trouble laying out the plane on a compound angle. The hole should be centered on the width of the flat and drilled through. 15° angle one way and 20° another way.

The ipt file attached is really messy in attemps to acheive the compound angle.

I am using Autodesk Inventor 2013.

AutoCAD Inventor :: Tube And Pipe Errors

Sep 25, 2013

I inherited this assembly from another user.  In making some dimensional changes the pipe runs have now errored.Not having ever taken any training courses in T&P, my knowledge is just based on simple straight forward runs.

This on the other hand is bit more complicated.  As you can see from the image I have this one run that has errors.My question is with the violation, is there anyway to pinpoint exacty what the violating member is?

AutoCAD Inventor :: Tube And Pipe Constraining

May 10, 2013

I'm just getting started using the Tube and Pipe environment for some of my work, and I've got what I'm hoping is a simple question with a simple answer. In the picture attached I've got a 1" pipe dropping down into a 8" pipe which I've disabled because it's a standard part right now and I want to replace it with a tube & pipe run. The thing I seem to have the hardest time doing when routing my pipes is aligning/offsetting my nodes with existing geometry in the assembly. In this case I want the end of the 8" pipe to be 12" offset from the centerline of the 1" pipe, and for the 8" pipe's centerline to be 12" below the bottom of the mezzanine's I-beam (as the standard part it is now). What's the best way to do this in the Tube and Pipe environment?

I tried "Include Geometry" from the "Create" panel but that only lets me create planes, which won't work with offsetting from the 1" centerline. However, SOMETIMES (it's a big sometimes) ALL of the options in the "3D Sketch" tab are available. When that's the case, I can go to the "3D Model" tab and create workpoints, axes, and planes. Sometimes, though, they're not all available, and I'm not able to place anything but planes. How I can change it so I can always use all the geometry of my assembly?

Also I'd like to know if constraing fittings and point-snapping routes to my assembly geometry in this way is the best way to do Tube and Pipe routes. Will doing this allow my routes to update if the assembly changes?

AutoCAD Inventor :: Copy Tube And Pipe Run

Sep 24, 2010

I have just completed an assembly and in this assy. I have a tube and pipe run. The original frame holding this pipe was 1m*1m*2m. We are now building a smaller unit with the same design. The pipe run is exactly the same except for the pipe diameter.

I tried to save as the pipe run to a new name and change pipe diameter but it gives me this error seen below. Do I have to make the whole run again? If i change run I have now to what I need for smaller frame I lose original sizes for first frame size.

Problems encountered while saving the document.

Save failed because the following files have been modified and must be saved together with Cooling_Skid_Type_I.Tube and Pipe Runs.iam:

AutoCAD Inventor :: Tube And Pipe ISOGEN Via PCF

Jan 18, 2012

Inventor Tube & Pipe can output ISOGEN files (*.pcf) for manipulation into piping isometrics via 3rd party software. I have done this and the pcf format is very poor on detail that it contains about each fitting. It required hours of manually re-writing the pcf file to get it to produce a result that was "good enough".

The Alias Isogen tool is rubbish - it crashes often, it does not make the changes that one has told it to etc. etc.

I eventually found Autodesk Plant 3D has an amazing piping capability (but it is 2D pretending to be 3D - so it cannot save as parametric solids) - however - it produces great piping isometrics. On studying the pcf from Inventor vs the pcf from Plant 3D for equivalent routes it is clear that Inventor is years behind in their piping functionality.

1. Does Inventor have plans to e.g. make their pcf compatible with Plant 3D so that we can process isometrics in that?

2. Any handy tool to manipulate pcf's to add e.g. welds, supports, notes, insulation, bolts, nipples/sockets/weldolets etc. to produce a comprehensive iso drawing?

AutoCAD Inventor :: Changing Tube Size

Nov 6, 2013

I am having a problem changing my tube sizes. Basically when I create a new route and populate the route, I want to be able to change the size without adding hundreds of sizes to the library. So I right click on the tube and select change size. The when I select a different size and select apply nothing happens? I push update and still nothing happens?

When I try to change the tubing size again it shows the size that I change it to but the tube doesn't visually change? I have noticed the same with the hose. What I also noticed is when you change the size on pipes it does change. How it is possible to change the piping sizes by right clicking on it and select change size when this function doesn't seem to work on the tube and hose?
