AutoCAD Inventor :: ILogic To Change Helical Curve In 3D Sketch
Jan 13, 2014I'm building a product configuration which includes some helical curves. I want to find out how I can change the direction of a Helical curve feature in a 3D sketch.
Variables like pitch and diameter are parameters, but the direction isn't.
AutoCAD Inventor :: Create 3D Sketch / Helical Curves
Sep 17, 2013I created a 2D planar sketch, now I need to create a 3D sketch and Helical curves, but as I enter into the 3D sketch mode, I cannot perform any functions, all my tool bar options are grayed out?

AutoCAD Inventor :: Variable Pitch Helix By Equation Curve
Jun 20, 2012You 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 :: ILogic Sketch Curve Counter
Apr 17, 2013Much of our work is structures fabricated from steel plate. One of our practices is to add a note " (SK) " to the description of plates that have a detailed sketch somewhere in the fab drawing set (simple rectangular or circular plates with no additional features do not get these detailed sketches). The actual "detailed sketch" is just a dimensioned drawing view of that plate.
I've been working on automating this process so that Inventor can actually determine for the user whether or not the sketch is required. I have it in certain part templates by default. Other templates add the note automatically through iLogic when certain plate features are selected, or when the model consists of multiple part features.
This leaves one remaining case that the current set of rules can't catch - when the user creates cutouts, notches, etc. by modifying the sketch for the original extrusion. I have determined a method for catching that case, but haven't yet figured out how to program it.
What I want to do is count all of the lines, arcs, and circles in the first model sketch. If that count returns a number other than 4 lines, the note will be added. If any arcs are detected, the note will be added. If any circles are detected with lines also present, the note will be added. There may be other cases that will come up in testing that need to be covered, but I ran into an issue before I got that far. Construction geometry messes up the count - I need a way to exclude it.
Below is the test code I have so far for the counter. what techniques I can use to get construction geometry out of the count. This code doesn't include the provisions for actually adding the note yet - I'm just trying to get the counter working right first. Instead it's just displaying the total count in a message box for test purposes.
oDoc=ThisDoc.Document
oSketch=oDoc.ComponentDefinition.Sketches.Item(1)
LineCount=oSketch.Sketchlines.count
CircleCount=oSketch.SketchCircles.count
ArcCount=oSketch.SketchArcs.count
TotalCount=LineCount+CircleCount+ArcCount
MessageBox.Show("Total Count "&TotalCount, "Title")
AutoCAD Inventor :: 3D Sketch Equation Curve - Creating Coil?
Jul 26, 2013I am trying to create a coil which from above, retains equal and thus parallel pitches whilst at the same time adheres to a semi-circular form in the cross section. You can see from the images attached that the first two revolutions are larger than the semi-circle outline.
These are the values I have used:
Cylindrical
r (t): 134.56924424045517662353735770102mm * t * 0.5
q(t): 1 deg * 360 ul * 3.0 ul * t

tmax: 0.916 ul
AutoCAD Inventor :: Constrain Line To Center Of Curve (3D Sketch)?

View 9 Replies View RelatedAutoCAD Inventor :: Rectangular Pattern With 2 Curve Lengths - 1 Sketch
Sep 19, 2013I would like to use a sketch as the basis for a rectangular pattern which is set up to use the curve length for both directions of the rectangular pattern so that when I update my rectangle in a sketch, the pattern automatically adjusts to the new sketch. I have sketched a rectangle, and used one leg of the rectangle to establish the direction and length of one dimension of the array.
However, when I try and choose the Direction 2, my only options are the entire rectangle or faces- I can no longer select other and choose a single side of the rectangle.
I was able to accomplish what I wanted by using two sketches, with the second sketch simply projecting one leg from the first sketch. Using one sketch just seems inherently safer than trusting projected geometry.Is there a way to accomplish this with one sketch instead?

AutoCAD Inventor :: Does Nvidia GTX 580 Work With GPU Accelerated Ray-tracing In 2013
May 25, 2012I´m running Inventor 2013 under Windows 7 64-bit.
Nvidia GTX 680 did not work with GPU accelerated ray-tracing in Inventor 2013. I replaced it with a GTX 580 GPU card, exact same result. Either I´m just doing something wrong, or it plain does not work.
Are there any consumer grade GPU cards that work with the ray-tracing functionality in Inventor 2013?

View 4 Replies View RelatedAutoCAD Inventor :: Create / Edit Sketch In Assembly
Mar 20, 2012I created an assembly of parts and then converted my assembly to a weldment. I then realized that I need to create a sketch and make an edit to my assembly. The sketch command is greyed out however. I did some trouble shooting and realized that once I converted it, it no longer allows me to make edits. Is there anyway I can get around this? do I now have to re-create the entire assembly to make this edit at the assembly level? If so this would really suck since it is a rather large assembly. I see saving as a new IAM doesn't work as well.

Oct 4, 2011I have this assembly shown in the pic. below. I'm trying to create a point or axis in the blue corner points (to attaches something later on) but it just won't let me choose it for some reason. I know that it's possible to to do that (almost sure I already done this trivial thing in inventor.)
Any reason it's not letting me choose the sketch points/line to in order to create points or axis(s)?

AutoCAD Inventor :: Helical Component Pattern?
Apr 19, 2012I have a sheetmetal assembly with helical shaped parts. I need to place about 50 little brackets and some corresponding rollers along the length of these helical pieces. The spacing is even so a pattern would be perfect, except I don't know how to get it to follow the shape of the part. The brackets are located to slots in the helical parts which were made with a rectangular pattern in the unfolded state. I tried to do a "feature pattern select" but it only saw the rectangular pattern as it is in the unfolded state (a straight line). I then gave up on patterns and started working on manually mating them into place but realized that the geometry of the slot was distorted (theory) and didn't leave me with any useable surfaces.

Not sure if this even possible in the real world sheet metal house to develop the flat pattern.

Jun 5, 2012When showing a gear in an inventor drawing they look good, but showing a helical gear SUCKS! The display, I realize, is very realistic to what you would see if you held the gear in front of you at this view point or that.
Problem is, I put a helical gear drawing on the shop floor and they machinist wonder why I have two rows of teeth on the gear (since it shows the front face and the helix'd gear teeth).
Any way to remove said offending gear teeth?
