AutoCAD 2010 :: Sweeping Threads In A Hole
Nov 7, 2012
How to use sweep to successfully put threads in a hole. Attached is the drawing with a helical coil and an object in two different orientations (A and B). To the right of that, you can see the path they took for each. The object rotated from the original position before following the path. Tried changing the position of the object to sweep, but either it sweeps it 180 degrees from what it is already doing (still wrong) or the program says it is invalid and won't do anything till I put it back in the original rotational position and try again.

My part does everything I want with threads but the other option I need to program is a straight hole with no threads. I assume I can do this with Param for the existing hole but not sure what it would be called? Is there a list or method of determining what these parameters are called so I'll be able to find them in the future?

I have an assembly that is made up of 3 unique parts ( 5 parts total). These parts and there features are to be laser cut, then assembled and welded along the outer perimeter in the small chamfer. I have designed the parts to have 5/16 holes, which will be later tapped to 3/8"-16 UNC after assembly.
Once these parts are assembled, I don't understand how I can change the holes to reflect this. Meaning I want the parts to be pre-drilled(laser cut) with 5/16 holes, but I want the assembly to then have 3/8-16UNC holes.
The hole command will not let me select the existing hole features in the assembly and add threads. What is the consequence of inserting a 'new' hole with 3/8-16UNC threads over the existing 5/16" holes in the assembly?
Is my workflow incorrect? should I have the parts modeled with the tapped holes and just make a note on the drawing to not tap these holes until assembly? how does that affect the laser cutting?

I am modeling an ASME pressure vessel with a 2:1 semi elliptical head upon which there must be a couple of lines of .375" trace tubing. I created a 3dpolyine that is the center line of this tubing, and joined all the segments into one so as to be able to sweep the whole thing and make one solid of the tubing run, but it simply will not sweep. I get a message this it is "unable to sweep the selected object." If I break the 3dpolyline, I can sweep parts of it, but the more complex the line segment, I again get the error message. I have attached a copy of the tubing centerlines.
The one on the left is the joined 3dpolyline, the one on the right is the 3dpolylines unjoined. (These were achieved using an intersection command of a rotated surface--the head profile--and an extruded surface--the tube tracing plan layout.) I have done this before, but only with the unjoined 3dpolyline, as in the right-hand example, but that is very time consuming as each segment must be swept. But I recently acquired a third-party LISP routine that joins the 3dpolylines into one. I'm thinking there must be a limitation on data of the 3dpolyline preventing the sweep, and wondering if there is a setting or system variable that will allow the more complex 3dpolyline to be swept.

I am trying to create a tube by sweeping a circle along a spline. I read many of the previous discussion threads on the topic but I still have some issues.
I first created my spline and transformed it in a polyline (some people recommended to do it). Then I created the circle. Finally I sweep the circle along the path.
The issues are the following:
1) when I look at the tube using the 2D wireframe mode, I can see that the primitives are not completely regular. In some points there are weird intersections and I don't know how I can fix them.
2) I hoped the tube was solid. However, when I exported (as .IGS) it and see in another program, I realized that it has only two circular caps at the extremities of the tube, but inside it is hollow.
I tried to transform it in solid or mesh or whatever, but it always gives me an error, saying that the object cannot be converted.

I've got a template with a set of Object defaults for an Inch drawing and a set for a Metric drawing. I've just noticed that within my metric set, if I insert a hole table with tapped holes, the font on the tapped holes doesn't match the other hole types. I'm searched around, but all the settings for the hole table style reference the same text style. (Please see the attached image.)
So is there a way to set a certain hole type to have a certain font or size within a hole table? Because if there is, I'd obviously like to remove it..... But I can't seem to figure out where the issue is.

I am trying to add a hole to an existing hole chart. I drop the part into a new drawing, set the ordinate "zero", and add a hole chart by selecting a few holes. When I attempt to edit the chart: click chart, right click "edit", click add hole, select new holes, right click to create, the "create" selection is greyed out and all I have to choose from is cancel. I searched the forum here but could not find a reference to this a know issue. Am I doing something wrong or is this a glitch of 2013.
We are running win7 x64 machines and this happens on both the 2013 Ultimate and Premium editions of the product.

I have had this problem intermittently for a few weeks since going to Inventor 2013 SP1.1. I have a part within an assembly and that part has holes created in it before assembling it with other parts. Now when I try and create a hole table in a drawing of the assembly I cannot select hole edges and the hole table is blank when trying to create it automatically from view selection. I originally thought it may be an alignment issue but I have since aligned everything correctly and it still persists. I can create the hole table if I import in just the part into the drawing but it will not allow me to create the table on the whole assembly.
I can also create the hole table if I use "centred pattern" and create cross hairs on all of the holes however it does not give me correct annotations for the holes as shown in attachment and I can manually change the annotations but seriously this should not be required. As shown in the screen shot it reads as A1 down to K1 instead of A1 to A10. .

Question: Is it possible to control the Hole Dimensions called out on the Hole Chart? As in controling leading/trailing zeros for main hole dim, alt home dim and tolerances? Can you combine the Main Dim with the Alt dim in a single column, separated with parentheses? (same with tolerance?)

I would like to use the hole command to place a hole in a part. When I place the hole it won't allow me to use one of the origin planes to locate the hole from. Can I only locate holes off edges?

I have an assembly that contains a part and a hole feature (the hole feature is at the assembly level). Using the api, I'm trying to get the hole location relative to the part's coordinate system in a without using the holeplacementdefinition.distance property, this way I can get the hole location regardless of the way it was defined.

I am trying to create a CAD drawing for the construction of Paddle Pop sticks. It is the basic shape of the Magnum sticks, but it is tricky because it has a 140 diameter taper, from the top of the jig to the bottom. I am trying to make the circle attached to the shape of the stick, and the Sweep the circle around the shape. But when I try to sweep it around, it says "The sweep results in a self-intersecting circle". I am using AutoCAD 2012.
P.S. I have attached the .dwg file so that it makes more sense.

While creating holes in a part, a small counter shows (when you click on a point) of how many holes there are.
Programs:
Solidworks (1998-2011)
Autodesk Inventor (R8 - 2013)
Autodesk AutoCad 2D
Autodesk AutoCad 3D
Catia V5

I'm having a problem sweeping a curved object over a spline. The object will sweep over a straight line...but not on the spline. I keep getting "unable to sweep object(s)" in the command line. I could be doing it all wrong... I've attached the file.

This has to be a bug in the program. I created a part, added a standard 5/8" threaded hold in it. It looks great.
I export to STL thinking that I can print this part on my 3D printer. There are no threads, just a hole. What is wrong with the STL export?

To create realistic threads, I simply sweep the thread profile along a helix with Align set to “no”. (This actually creates the negative of the thread, which must then be subtracted from a cylinder.)
When I attempt to follow the same procedure using a conical helix to produce tapered pipe threads, however, it does not work. When I set Align to “no”, I get an error message saying “cannot sweep the profile”. If I try it with Align set to “yes”, the profile is twisted and the result does not look like threads.
Any way around this issue, or is this a fundamental limitation of AutoCAD?

How to properly model a screw thread around the point of the screw.
I have gotten the coil to taper to the point, however, I'm unable to get thread to terminate properly.
Essentially, the pitch remains the same as it moves down the taper, but the major/minor is diminishing until it terminates cleanly at the point.

I heard that AutoCAD use Mental Ray render. How many maximum parallel threads can use this algorithm? I want buy new graphic station based on dual-socket Intel Xeon (each CPU has 6 cores with Hyper Threading technology). Thereby a computer will be equipped with 24 logical CPUs.
Can AutoCAD 2012 fully utilize such a performance for parallel computing when render?

I have made threads with the standard thread tool (that doesn't seem to make 3D threads but instead pictures of threads) into solid and once I export the STEP file and open it in Solidworks the threads are missing. I have to export the drawing to STEP for machinist that uses Solidworks. How can I include the threads into STEP file?

I have a hole tapped from both sides. I did a hole tapped to a depth but drilled through and added a thread feature at the other end. I had changed the hole (from 7/8-9 to 1-8) but the note on the drawing was attached to the thread feature.
I would like to set it up so that the thread feature will automatically be the same as the thread on the hole. I don't get any errors saying that the hole is the wrong size for the thread, and both ends of the hole look the same (which I find somewhat disturbing).
I need to link the threads together. At the very least it should look wrong, and hopefully complain that it's wrong, but I would much rather have access to these features so I can control them better.
