I have a group of Points coming from a step.file. So I don't have their coordinates, excel list or anything else. Just the step file. Around 100 points. There is a line between each 2 consecutive points.
Is there any way to select all the points and create a complete spline? Or even to select all the points and create tangent arcs between all of them?
I need to be able to extract all "X" and "Y" axis points from a "spline" created in a 2D "sketch" and display them in the "Debug" window (for test only).
View 3 Replies View RelatedI am trying to create a 3d surface by importing points from an excel file. I have been using "import points" in the 3d sketch mode, and checked off the box that says "create 3d spline." But this just causes Inventor to freeze and crash. My excel file had about 2000 points, all of which lie on the surface I want to create in Inventor.
Should this method work in theory, and do I just have too many points?
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 3 Replies View RelatedI have a spline that goes through 4 points:-
x1,y1 - x2,y2 - x3,y3 - x4,y4
The spline is of degree 3 and is fixed at points x1, y1 and x4, y4.
What i need is the equation of the spline.
Is there anyway of calculating the equation that represents the spline?
I am working on a little lisp routine to draw splines, but can't get it working. The basic idea is that i first select a set of points that i can feed to my spline command.
(defun c:test2 () (setq pt (getpoint "
define point:")) (setq ptlist nil) (while (not (equal pt nil)) (setq ptlist (cons pt ptlist)) (setq pt (getpoint "
define point:")) ) )
Now i need to draw a spline based on these points. My plan whas to simply use the acad command itself. But this option didn't work.
(command "spline" ptlist "")
Then i tried using the vla-addspline command. But i can't even get this one working .
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.

I 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 know there is a Spline command in the AutoCAD.
Can I create a B-spline which has two endpoints and two control points in AutoCAD similar as the one in the Solidworks?
When I create a curve using spline on the screen I have noticed that often the curve between the points of the spline will become as straight lines. When I click on a point the curve appears again as normal and as I wanted. Any way to stop it from happening? Is this simply a characteristic of AutoCAD or something I am doing wrong? Does the curve appear as desired when plotted? The curves I am referring to are sections of a ships hull.
View 2 Replies View RelatedAs you can see, the nature of my model forbids me from making a 3D solid using LOFT.
The top surface is consisted of 3D polyline and arc, which if "joined" will be become a spline.
The bottom surface can easily be joined into polyline.
If I loft the top and bottom, it'll only give me a LOFTED Surface, which is not I want (wanted a 3D solid).
Basically I have 3dpolylines and some Splines. I would like to create a road file that uses the geometry of these objects to create a single line/crest of road file.

Extruding is not possible because of self intersecting path.
I want to trim both two free ends from the intersection and also close the intersection for extruding this profile. However ....., without displacement of any current point in the perimeter of the closed spline!
I have created a shaft and splined one end of it successfully. The shaft is the same diameter at both ends and I need to spline the other end as well but when I try, I get the following error messages, Cannot create iFeature. Not possible to create shaft groove. Splining the first end went without a hitch but Inventor absolutely refuses to spline the opposite end of the shaft. The shaft diameter is correct for the spline I have chosen (same as the major diameter)
View 1 Replies View RelatedIn 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.
I have a spline that runs through about 70 points to make the perfect line. But when I rotate the sketch the spline turned from green to black and is no longer recognised as a boundary. I then have to delete the black line and re-draw. How do I keep the spline green and usable?
View 3 Replies View RelatedWhen attempting to break the link on a projected spline, the spline type reverts to what appears to be the legacy AutoCAD type of spline (see image).
Is there a way around this other than drawing a new spline on top of the projected geometry and working with the new spline?
The idea was to project the shape, break the link, then ,ove the shape to a new location in preparation for a lofting procedure.
Is there a way to disable visibility of spline end squares, in a sketch?

I am currently attempting to dimension to a spline in an orthographic drawing and running into some issues. I can't seem to find a way to properly dimension rather than making microscopic holes in the piece and that way giving the .idw something to grab on to for dimensioning.

Essentialy, I want to make a closed path from a spline and a straight line— this will become a custom shape that I want to turn into a solid. Is it possible or should I just use the split feature?
In the end, I am trying to make a solid that is similar to a section of this necklace, minus the curved portion that connected them to the necklace, itself.
I am drawing an airfoil profile in Inventor for use in a CFD package. I have a system of points which I am plotting and connecting via the spline function and extruding them to form my blade profile. However, when I open the drawing in the CFD programme, it is recognising the spline as a series of straight lines instead of one continuous enclosed shape. The CFD programme I am using require a negative (i.e a solid drawing of where fluid is flowing). I have attached the inventor file I have created.

View 1 Replies View RelatedI have a client who is replacing a large fleet of machines located in premises throughout the country. In theory the replacement program should be straightforward..... however machine dimensions have increased slightly, new service access doors have been added and user control switches and indicators have moved. I have Inventor Assemblies of the machines to show the door and body changes, but not the complex user interface panel (buttons and switches). If I could only import a sketch of the interface panel, it would look great in an Inventor drawing and I could dimension the all important position of components on the interface panel.
I have PDF drawings of the fascia panels which I can import to Adobe Illustrator and save as a DWG. When I look at the DWG in AutoCAD Mechanical, all looks well. When I import the drawing to Inventor part sketch however lots of spline control vertices appear. I cant delete the control vertices in AutoCAD or the drawing falls to pieces when imported to Inventor.
How then do I hide the vertices from my sketch in Inventor. Am I doing things the hard way? Are there shortcuts to importing PDFs in Inventor?
Inventor 2013 sketch mode is excellent as I only have to change one dimension to scale my sketch. I can also stretch/manipulate the sketch to make up for any errors in the original PDF.
