AutoCAD Inventor :: Self Intersecting Surfaces Helix Profile Sweep

Oct 8, 2012

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 am working with Autodesk Inventor Professional 2011, 64bit, 8gb RAM, Windows 7, Intel Core i7-2860QM.

AutoCad 3D :: Unable To Sweep Object When Attempting Helical Sweep For Pipe Thread

Dec 22, 2012

I am attempting to model an internal 1/8"-27 NPT thread, both the through hole and the tapered part of the hole are modeled, but after I draw the helix and the polygon and orient the polygon to the helix correctly, (or even if I don't, I have tried it) it keeps saying unable to sweep object. I am using Sweep with Alignment with the No option. If I select the polygon first, then click sweep, it works, but rotates the polygon so that what I get ends up looking nothing like a thread profile.

I have tried reducing the polygon radius down to a ridiculously small value, thinking it might have been interference due to a possible trig miscalculation, but with no success, still have the same issue. FYI, I am using a .037" turn height for 27 TPI and a polygon radius of .0214", with a helix small end radius of .177" and large end radius of .189".

AutoCad 3D :: Unable To Sweep The Cutting Tool

Sep 4, 2011

I want to sweep the "cutting tool" through the helix to create a inner thread of my nut. When i set "Align" to "NO" it refuses to sweep. If i set "Align" to "Yes" it works perfectly but the result is of course totally wrong.

AutoCAD 2010 :: Unable To Sweep 1 Selected Object?

Jul 28, 2012

I've been following the Convert 2D to 3D video that is given in the Help section of AutoCAD 2012, and whenever I try to sweep the handle using the same methods that were used in the video it says that it is unable to sweep 1 selected object (when I select the path). I've attached the DWG file.

Also, when I went to use the 3D align feature I did exactly as the video did, but my handle wouldn't align with the side of the mug. It kept lining up with the side but never between the top and bottom of the mug like you'd expect. I kept having to move it to get it down where it needed to be.

AutoCAD Inventor :: Unable To Edit Hatch Region

Sep 27, 2011

I successfully created multiple hatch regions in a sketch on a section view in a drawing.  I want to change or delete one of the hatch regions, but am unsuccessful.  I clicked on Fill/Hatch Region and then selected the region that already has a hatch defined, but the dialog box does not show that these is a hatch defined. 

If I click the hatch button it creates another hatch over the top of the current one and does not allow the current one to be deleted or changed.  Of the four regions in my sketch, one works and the other three do not.

AutoCad 3D :: Create Series Of Trays In Shape Of Letters - Unable To Sweep 1 Selected Object

Aug 14, 2013

I need to create a series of "trays" that are in the shape of letters. I am having some success with certain letters, but zero success with others.

I am creating these letters using a curve brought in from illustrator, and sweeping the profile that I want to use around the curve to create the outside.I am then using presspull to create the base of the tray.

However, sometimes the sweep command will simply say "unable to sweep 1 selected object" with no explanation as to why.

Sometimes I will get the shape that I want, but it is facing the wrong way, and I cannot fix it. Other times it will simply stall and then delete both the curve and the profile.

AutoCAD 2013 :: 3D Wire From Helix

Nov 8, 2012

Haven't used AC in a while and hoping this is a simple question, trying to take a polyline (in this case a coil shape) and add a diameter to the line. This 3D object will then be imported to COMSOL for some thermal expansion modeling.

Is there an easy way to do this?

AutoCAD Inventor :: Templates For Auger Helix

Nov 29, 2012

I am working on a project that involves a screw conveyer(auger) with a 3" od, 1.5"/flight and a 0.800" ctr shaft.  I modeled it without any difficulty using the "helix" function in a 3-d sketch & then swept a rectal around that path.  The problem is, I need paper templates to layout the pattern on the steel.  In the past I have made use of the "flat pattern" feature to print paper templates for tube notching and such, but that function prompts me with an error message "no surface to flatten"  Attached is the full screw(augShaft9in.ipt), a single flight and 2/3 of a flight(i dont think a full flight will flatten & not overlap). Need to getting these patterns printed.

AutoCad 3D :: How To Join Helix Onto 90 Degree Bend

Oct 16, 2012

I'm trying to join a helix onto a 90 degree bend but I can't get the 2 ends to marry up.

I am self taught so I don't know all the commands but I understand the concept from using Maya / 3Ds Max in the past.

Also why do I see the diagonal lines at the end of the 90 degree?

AutoCAD 2013 :: Loft Triangle Around Path Of Helix?

Jun 11, 2013

I am trying to loft a triangle around the path of a helix. I want the top point of the triangle to be facing in such that the ouside surface is flat (in the veritcal direction) for the entire helix and I have the two triangle cross sections oriented to do as much.  Whenever I try loft it, autocad associates sides of the triangle that aren't supposed to connect causing the triangle to twist along the path.  Is there a way that I can easily tell autocad which sides I want to connect?

I create a helix, two turns, base diameter = top diameter = 3, helix height (each turn) = 2.

Why when I look it from the top view, its shape is not a perfect circle?

Should it be a perfect circle when it looks from the top view, isn't it?

AutoCAD 2013 :: Using Helix To Make Thread And Matching Bolt?

Apr 8, 2012

I have a helix I've made, and I want to turn it into a thread in a hole I've already made. 

I'd also like to make a matching bolt to fit the said thread. Keep in mind my thread speficics are not importan this is all merely for a proof of concept. 

I do know know if auto cad offer a say to make a bolt and so on w/o too much work -but I've attached the said file and the helix I'm concerned with is in the "threads" layer.

AutoCAD Inventor :: Variable Pitch Helix By Equation Curve

Jun 20, 2012

You can create a variable pitch helix by using the Equation Curve feature introduced in Inventor 2013.

Create a new 3D Sketch. Start the Equation Curve command.

Here are equations that I use to create helical curves. Many other variations exist.

Cartesian coordinates:

x(t) = radius * sin(360 * num_turns * t) 
y(t) = radius * cos(360 * num_turns * t)
z(t) = height * t

[Code]....

When you sweep a profile along a helical path, use the plane normal sweep (instead of perpendicular sweep) to orient profiles suitable for coil or spring.  In the example below, the sweep path is a constant radius, variable pitch helix.

AutoCAD Inventor :: Helical Gear Tooth Profile / Get The Right Helix Angle With Coil Tool?

Dec 8, 2012

I have generated a gear set using inventor. Now I would like to 3d print the gears. I have uesd the export tooth shape to get the true tooth profile. now I am attempting to use the coil feature to generate the helical tooth. The problem im running into is in the coil tool I can only give it a Revolution and height dimension. The hight is the width of the gear, but I am having a problem converting the helix angle to the "Revolution" perameter. I have read other posts and they say that it is Helix angle / 360. I have tried that and then compared it to the original gear generated by inventor and it is not even close. I need to do this on in internal gear and match it to an external gear.

AutoCAD Civil 3D :: Surface Not Extending To All Included Points

Jun 25, 2013

2013 version. Long story short, I am having problems with pressure networks in my drawing so to simplify things I want to just show the top of the current watermain in my profiles because we are not doing anything with the water main, though it needs to be shown in the profile. To do this I created some points where the watermain is and made their elevation 1.8m lover than the existing surface at those points (due to the 1.8m of cover the watermain has).

I then created a surface using those points and an outer boundary surrounding the points. For some reason the surface stops at one point and doesn't continue to the rest (about 5 more points). So when I create my profile the surface stops short. The points are included in the point group the surface uses, and the outer boundary doesn't cut them out either. Not sure why the surface isn't referencing those points.

AutoCAD Civil 3D :: 2014 - Point Group (NO DISPLAY) Does Not Appear To Be Included

I just started work in Civil 3D 2014 and was going about creating different point groups for some volume calculations so I could create different surfaces.  I noticed after creating my first point group that the NO DISPLAY group could not been seen in the Prospector under Point Group.  Now in previous editions there has always been a NO Display Group so you can easily view your different groups.  Is this something they changed in Civil 3D 2014 or was the installations faulty?
