AutoCAD Inventor :: Alternative Packages Not Recognising Spline
Jan 23, 2013
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.
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.

I have a folder that contains subfolders, then more subfolders. All these folders contain Inventor files. There are few different models there with drawings and related files...
I need to make an exact copy of the folder at different location in Vault. To use Copy Design tool, I would need to do it few times, as there are few totally separate files in the folders.
Now, is there a way of taking main folder with its all contants and just copying/renaming it to other location? It would save me lot of time.
I'm having a minor issue with Autocad 2013 at the moment. I use the Quick Properties box to change a lot of my object properties, but since changing from 2012 to 2013, I have noticed QP doesn't recognise the selection of any objects.
Describe the advantages and of producing drawings electronically using CAD compared to manual drawings and sketching. When describing the CAD packages used in architecture, mention how they can be linked to other software that can aid the design process of construction.
I've done the first part, not so sure about the second part:
" When describing the CAD packages used in architecture, mention how they can be linked to other software that can aid the design process of construction."
I just upgraded my RAM from 2GB - 4GB. I'm using PS CS2 on a Dell Precision 380, with Windows XP Professional, vers 2002. While my computer recognises the upgrade in memory, when I go to 'Preferences' within PS it still tells me that only 2gb is available - any ideas on how I get PS to recognise the extra RAM?
I have an iMac which had 4 gb of ram. Photoshop defaulted the usage to just under 3 gb. I installed another 8 gb of ram but PSE fails to recognise the extra ram so I can only get it to use 3gb. If I reinstall will it recognise all my ram? Will I still have all my photos on the organizer?
Here I enclose file Cam_Profile.ipt, this is a spline curve made from an Excel matrix with 670 points in 3 decimals accuracy (VBA editor) 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)
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?
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.
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?
how to properly create one 8x10 image. Since the picture package dialog box doesn't seem to allow cropping, I get white area along the sides of the completed image when I go to make an 8x10 on an 8x10 sized canvas.
Is there any way around this? I know I could just do it all manually myself, but this is not the point of an "automated" tool.
If photoshop can't do it, are there any other software packages that will let me create custom picture packages and save them as JPGs?
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.
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).
I am totally new to Inventor. I have a lot of experience in Illustrator and Photoshop; what I want to do is possible in those programs, but I have not figured out how to do it in Inventor.
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.
How to pattern a feature along a spline curve so that the resultants are separated by an equal linear distance (chord length), rather than as a function of the spline curve's length?
I 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.
I 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 want continuously to display the loop measuring of a Spline/Arc/Line/Slope (or even have it as a dimension / parameter on a sketch/part) because it change in relation to the block-position that constrains to the slope.
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 ?
How 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.
I am now trying to model a fuselage for an RC plane and am trying to copy a spline from one work plane to a new one and link them together so that if I edit one, it is reflected in the other. Copying and then pasting into the new plane doesn't link the two splines together.
