Many times I see that these types of irregular shapes which comprise of spline curve are created with very less or no dimensions, so I want to know how this spline curve was created and can be controlled, if I want to create it in an exact manner what dimension I should use ?
View 2 RepliesHow to curve a piece of sheet metal over the outside curved edge of the attached part. I can do it the old fashioned way but was wondering if it could be done in sheet metal which would give me the flat pack automatically (that way there is less chance for errors). There are several of these baffles joined together by a spine and the sheetmetal will eventually go over all of these, and have a few modifications to shape the end profile.
The outer curve is a spline which has changing radius and hence to use a contoured roll would be rather difficult and time consuming (there are also some flat sections at each end of the curves as well).
Autodesk Inventor Professional Student 2013 is the version I'm using.
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 am trying to create a 3D meshed surface from an irregular shaped solid I created using firstly a SPLINE, FILLET, PEDIT, and EXTRUDE. I have a solid in the basic shape now, but I am trying to create a meshed top and bottom (x, y, z,) to change the contours of those surfaces. I have looked at 3DMesh but it asks for (n,M,) coordinates like it is a regular shaped surface (square, rectangle) where one can calculate the required even spacing needed.
My goal is to create in CAD something like a fine art carved piece of wood, with irregular shaping and no straight planes or surfaces.
I have included a basic picture in JPEG format for your review. This is the item from which I am trying in ACAD 2010 to construct into a usable adjustable form so I may parametric for my needs.
While tracing a tree image using splines for a school project i have run into some problems...I am creating a pattern for a plasma cutter.
When i move the points of my spline sometimes it causes the whole spline to randomly move around and twist and turn where there are no points. Also sometimes when i open the drawing some of the spline lines are out of place while the spline points have not moved.I have tried to constrain all the points but it turned into a mess.How can i stop this from happening?
I'm trying to create an external involute spline (ANSI B92.2M) Fillet Root Side Fit 26.9mm x 1 mm x 26 teeth x 38 mm long using the spline generator with Inventor 2012. I created a test shaft"M-182-AMA.ipt" that is Ø26.9 mm x 38 mm long with 1 mm radius on each end of shaft.
I use the following steps:
1. After creating component "M-182-AMA.ipt" I select Design tab>>Power Transmission>>Involute Spline.
2. A window appears that has the caption "Involute Splines Connection Generator".In the Dimensions section I choose "Splines Type: ANSI B92.2M - 37.5 deg, Fillet Root, Side Fit, 26 x 1.00 x 38 x 5H/5h" and change the Length to 38 mm.
3. In the Shaft Groove section I use Create new, and I push the Reference 1 button that turns blue, I then select the od feature from the model and I get an error(see attached pic "error1.jpg).
I changed the 26.9mm od to be 27mm and it still gave me the error.

View 2 Replies View RelatedI've been trying to make gimp-curves-spline get variable (which is number)instead of number and I get error.
For example -when I do:

everything works well as it should be.
but if I do:*(define spoint 15)*
*(gimp-curves-spline drawable 0 6 #(0 0 0 spoint 255 255))*
I get an error: *Error: Item 4 in vector is not a number (argument 4 forfunction gimp-curves-spline) #( 0 0 0 spoint 255 255 )*As you can see, all I did was replacing the number 15 with a variable(which is a number) I also check it is a number by the *number?* type predicate

I have a skeleton with baked motion capture keys on every frame. I'm wondering if there is a method to convert these baked keys to curves, so it will be possible to start cleaning up the animation. I'm fairly new to dealing with mocap. Perhaps there is a method for achieving this in Motion Builder rather than Maya, that I'm not aware of?

View 3 Replies View RelatedQuite often I need to measure shortest surface distance between two points (electrical tracking diatance) as in pic below.

As a background....I am coming off of 10+ years using Catia (that's the software the company used) and have moved to a company that uses Inventor instead. I have used inventor for the past year.
In the past (Catia) it seemed pretty intuitive to create the vertical and horizontal during the creation of the sketch in such a way that would reflect the way you would want it defined as a view in a drawing. As well as controlling the preferred screen view (vertical +’ve to the top of the screen and horizontal +’ve to the right of the screen)
As per a previous post....I have tried the "Edit Coordinate System" but find it difficult to control the Vertical and Horizontal axis independent of each other.......
I understand that "functionally" there is no issue...but it becomes quite disorienting in a complex model when going to edit a sketch and the model spins around, showing the sketch in an orientation that doesn't relate to the models features, or "sketch related" features.
It becomes especially difficult/confusing when modifying/checking other peoples models as well.
I just wanted to support the need for this functionality. In the end it just enhances the flexibility of the software and maintain some amount of definable company standard work procedures for modelling.
Maybe it hasn't been included in the software because of proprietary reasons? I would hope there is a reason.....it seems like there are people out there who would utilize it.
If I want to control a mechanism assembly, like an excavator, on screen with a couple of joysticks, how can this be done?

I have an assembly drawing which requires a break in the drawing view due to its height. The drawing view scales accoring to the change in height (so it remains the same physical height on the drawing), however I need to be able to increase/decrease the height (or value) of the break linearly to the height of the assembly.
I had a look at the ilogic 'break sample' and tried to adapt it to my needs, however, i couldnt get it working. I am using Inventor 2012.
1) I have assembly containing pipe and a flange. I want flange size to correspond pipe size. In other words, when parametrically change pipe size, flange size to be updated automatically. ( do i need to have two parts - pipe and flange, or it can be one assembly without need to create parts?)
2) Is it possible to control type of flange (slip-on, weld-neck.. etc) by parameters or need to make different assemblies for different flange type?
3) Then when flange and pipe sizes are updated would like to make overall length of that assembly whole number (since hub length changes with the flange size). how to round that overall length to integer?
I've been running into issues in IV 2010 with the shading where I need to show a part in a perspective view on my IDWs and depending on the angle I rotate to the majority of the part is shown in shadow. It's frustrating because I need to show a feature in that particular orientation, but the whole part looks dark.
Especially when I am showing left and right mirrored parts. One side always seems to end up dark. FYI I almost never show the material as a texture map in my part drawings so I use white as the color default because I am simply trying to get across the shape of the part in a shaded 3D view. These don't really serve as renderings to me per say. Is there any way to control the light source direction for custom views in terms of shading? Could I make it more of an ambient light or similar to the Global Light Style in Inventor Studio.
I have a browser display issue that occurrs sometimes when imported parts are inserted into an assembly model. Before dropping some imported parts into my assembly model I changed the filename to something corresponding to our part numbering system. When the part is dropped into the model, the name of the instance displayed in the assembly browser is the same as that originally used by the originator of the model.
I know I can change the name in the browser by editing the name field in the occurrance tab; but I'd need to do this for each instance. What iproperty field (or other property field) should I edit at the part level so that the revised part name is used in the assembly browser whenever that part is inserted into an assembly?
I have made a family of weldments. I am having trouble controlling the visibility of the weld symbols when I place one of these members. On some members the welds are shown and on others they are not. I know that I can turn off all the welds (View>Object Visibility> Weld Symbols) but there are other weld symbols in the assembly that I need/want to leave visible. In the image below all three weldments have the same welds, but the weld symbol of only the one is shown when I place it in an iam.
In each member of the iassembly, I have unchecked the visibility under the Welds node, but some are still visible when i place them, so that must not be controlling it. Sure would be good if visibility of welds were controlled by view representation.

I am setting up a family of parts that consist of a round disc with a fixed OD and a circular pattern of notches cut into the OD. The notches must go to a certain depth from the center, so those parameters are set. My problem is that I need to control the amount of material left between the notches, along the OD, after the pattern is done. Given the fixed parameters of the major OD, minor OD (3.5" in this case) and number of notches, the only way to control the amount of material between notches is to change the angle. When I set up the sketch to do the notches, I can only get a fully constrained sketch if I assign a specific angle to the notch. I need to be able to set it up so that the angle of the notch varies so the end result is a specifc amount of material left after the circular patter is completed.
In the attached PDF, I show what I have done so far. In this case the OD of the part is 4" and the diameter of the notch at it's closest to the center is 3.5". So basically, I end up with a driven parameter of 0.443. If I assign this value the parameter of d14, I need to make it equal to a ratio of another parameter (let's call it d15) so that d14 = d15*2.. This can only be accomplished by changing the angle.
In my family, the major OD and minor OD remain the same, but the angle must change to retain a specific amount of material between the notches when the number of notches is increased or decreased.
Is there an iLogic rule I can write to control this?

In Vers 2013, IV finally added the ability to manipulate a [3D] spline by dragging the control handles (way behind the curve on this one).
However, dragging "a" control handle causes several of the other control handles to shift as well. Puts a big limit on the ability to customize yout path. Splines are supposed to be one of the unrestricted free form tools for modeling.
Is there any way to turn this "feature" off ? I need and should be able to have discrete control on each control handle. (I had this way back in SW)
Also, there is no 'axis' for the control points unless you count the const lines that connect the control points and I don't. I should be able to select an axis and be able to shift the direction and level of influence of each side of the control point axis.
