I 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?
I am running 2014 Pro Design Suite.
I am trying to create a 3D sketch of a helical curve that has an accelerated pitch.
View 2 Replies View RelatedI'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.
Given a sketch, I wish to get its profile paths (outer, plus inners), for each path, I wish to get their individual curves (line, arc, splines, any type). For lines, I need start and end points, for others, some sample points would do.
For "T" like thin profile shape, following code got me, 1 Profile Path, which had 8 Lines (thus 8 points) and it worked fine.
For Each path As Inventor.ProfilePath In extFeature.Profile
If Not path Is Nothing And path.Count > 0 Then
For Each entity As Inventor.ProfileEntity In path
If entity.CurveType = Curve2dTypeEnum.kLineSegmentCurve2d Then
Dim oSkE As SketchEntity = entity.SketchEntity
Dim oLine As SketchLine = CType(oSkE, SketchLine)
Dim startpt As Inventor.Point2d = oLine.StartSketchPoint.Geometry
Dim endpt As Inventor.Point2d = oLine.EndSketchPoint.Geometry
But same logic does not work (crashes at Casting I guess) for "S" shape as below:
It gives path.Count == 0.
I need to create about 100 off points in a sketch.
I have the x and Y co-ordinates in a excel spread sheet. Is there any simple way to create the points other than manually entering thru precise input.
API enhancement/fix in SP1: Cannot create a radius dimension on circular drawing curves projected from spline edges.Does it in some way trying to refer to the issue with nonplanar arcs turning into splines in drawings saved-as AutoCAD .DWG?

View 3 Replies View RelatedI created a 12-sided polygon shape in the sketch mode. I created one line, fully constrained it and then used the circular pattern to finish the shape. Why can't I extrude the shape?
I have attached the file. It's a pretty basic shape. I don't understand why it wouldn't work...
creating a named sketch block (in an ipt) containing entities that I have created in the same sub? I'm doing this from Excel, in Inventor 2010.
What I have:
Function CreateUncutTagSketchBlock()Dim IVApp As Inventor.ApplicationDim oDoc As DocumentDim oCompDef As ComponentDefinitionDim oSketch As SketchDim oTG As TransientGeometryDim FileName As StringDim Coords(1 To 10) As Point2dDim oSketchCircle As Circle2dDim oSketchArcs(1 To 2)
[code]....
note that i've also taken a shortcut with the arcs, and the circle. I did try to create them using the same naming convention as the lines, but... I failed to implement it successfully.Also, I can not quite figure out how to constrain all the start/end points together.
Why I cannot create a extrude feature for the sketch3.
View 4 Replies View RelatedI 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.
View 5 Replies View RelatedI 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)?

I am trying to create a sketch on a face for an extrusion. The sketch has a text box. I am having trouble excluding the text in a sketch otherwise all the closed geometries of the text get extruded.
I created an objectCollection and excluded the TextBox objects. Still not working.
I am not sure exactly why this is a limited feature of Inventor 2011 but when you want to select a sketch to create a boundary patch you have to select each part of the sketch in sequence. It's a pretty laborious task. I am looking to a way to automate this using i logic.
View 5 Replies View RelatedIn 5.3 I can create reference dimensions in sketch mode to my hearts content. They became very valuable as I would use them to determine placement of multiple features. Now, in IV 7, I have alot of trouble creating reference dimensions from adjacent features on the same surface. I have to change the way I'm working now and it has stumped me on a few occasions. is there a "new" feature I need to enable or is this the cost of progress?

Can i write a Macto that gives me constraint rec block in sketch. This feature already available in Inv12.
I 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.

View 9 Replies View RelatedI'd like to add a sketch to my drawing - a sketch that is independent of any other views. Is it possible to make this sketch have a scale associated with it instead of being 1:1?
Right now I am just overriding all of my dimensions.
I use the same sketch to create a break out view in one type of drawing. I may be blind, but I can't seem to find a way to save that sketch and reuse it when I want to create a break out view.
View 4 Replies View RelatedIm trying to create a shape like the attached image using sheet metal loft from one sketch to the second sketch. No problem doing that but i want to extend the neck on the small end 1 inch like the attached image.
Currently the product is produced using 4 panels brazed together. I want to create the product with 2 bent panels 90 degrees that are split apart from the loft.
Not sure if this even possible in the real world sheet metal house to develop the flat pattern.
I am trying to recreate and 3D model the impeller of a heartmate II LVAD (URL....) but I am having problems with the sweep along the helical path. The profile is the vertical line and the path is the helix. I want to use a surface output for now. I had to use Solidworks to generate a variable pitch helix and import into Inventor.
View 2 Replies View RelatedWhen 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?

Is there an option somewhere to stop Inventor automatically rotating the view when I create or edit a sketch?
View 2 Replies View RelatedI am using projected and sketched geometry (2D sketches) in assembly space to create lines/ points that I intend to use to define planes and axes. The problem I have is that nearly all the geometry I create (lines and points in 2D sketches) is not "selectable" when I try to create planes or axes. I cannot even put a work points "on top of" my sketch points. Why are my sketches not usable in the assembly space? Since the components in my model are just two extruded rings I don't have any linear edges I can select to make this work/ define planes.
View 9 Replies View RelatedI want to draw a line between the two sketches visible on the image below. The line should be in the plane visible. The starting point of the line should be from wherever the top sketch intersects the plane of the current sketch. The finnish point of the line should be wherever a line of the bottom sketch intersects the current sketch plane.
There is no tooltip appearing that would allow me to quickly "attach" the starting line to the correct position. Is there such an aid, and how do i turn it on?
I am having a difficult time centered the helical path (the equation curve) and lofting the two profiles (centered) through the helical path in the axial rotation direction..
View 5 Replies View RelatedAny time I click on "Create 2D sketch" when editing a part in place in an assembly, the view moves to an isometric view. It happens as soon as I click on the button. Is there any way to stop this happening?
This does not happen when I'm editing a part (.ipt) on its own. I'm aware of the "Look at sketch plane on sketch creation" issue: this is not the same thing since it happens as soon as I click on the button, i.e. before I actually create the sketch.
I want the view to remain as it was before I click the button, to keep the things I'm looking at in view.
How to draw in Autodesk inventor Helical Gear using Flex option (this option you can find in SolidWorks) below I put link to SolidWorks where this options allow to preper gear by rotation of existing solid. Where do i find this option in Autodesk?
View 9 Replies View RelatedI'm trying to draw a helical staircase with a bottom plate underneath the steps. Drawing it isn't a problem. I used a sweep with helical curve. Then I converted this part to a sheet metal. But then inventor doesn't want to unfold it. how I have to make a flat pattern from this one with the necessary bending lines?

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.
