AutoCAD Inventor :: How To Twist Object Properly
Jun 10, 2013
Essentially, I am attempting to create something similar to this: [URL] .....
But cannot get enough twisting action. I just need to know how to twist an object properly. For example, what I have done is created a two sketches of hexagons on offset planes, and lofted between the two sketches. If I rotate one hexagon sketch slightly, it will result in a twisting effect. However, if I want to get any significant amount of twisting, rotating the sketch does not work. I have tried with a goil, but that gets the entire object (with a sweep, in this case) to spiral.

Is it possible to twist a bar shape. I have the inventor part file as well as a jpeg file of what the device should look like. Is it even possible with inventor or fusion.?

I have the following sheet metal application: A flat bar steel (strip) 40x1mm is bent and twisted around three cylinders. In our process, the strip is running in loop around these cylinders, like a conveyor-belt. At first, it is bent around the first cylinder (blue). Then, it is bent and twisted around the second cylinder (green). Between these cylinders, a flat part is modelled so that the strip will be bent upwards (twisted) around the next cylinder. The same is done between cylinder two and three. In praxis, when I bend the strip, no flat part will be present, because the strip is quite stiff, as it is spring steel. In my Inventor model, no stiffness of the strip is taken into consideration.
I am looking for a better way to model this strip, where stiffness of the material is taken into consideration.

I am trying to model a forged steel table base so I can create some tooling to reproduce it. See the attached photo of the base. I am able to sweep along my 3D projected sketch path but there is a twist at the center that I believe I need a guide rail to control. I have tried to draw a rail but it fails.
I suspect I am not drawing my guide rail correctly as to create the slight twist. I was considering drawing a shallow helix along the 3d sweep path but not sure that this is the best direction to head next. I have attached the .ipt with the sweep (without guide path being used).

I'm drawing some objects in illustrator and when I stroke it, it's clear that the color is not staying or not matching the object. I took a picture of it.. I drew a lot, but this is the first time that it is happening.

I am working with vectors from AI as smartobjects in PS. In CS6 the dropshadow effect started to look weird.It's to dark, offset and to big. If I scale the smartobject in PS the dropshadow changes, too. But it's never as it's supposed to be.Here is a screenshot. Left is AI, middle PS CS5, right CS6. URL....
Is there a setting I have change to make PS CS6 handle smartobjects with effects nicely again?!

I’ve attached an image of what I'm trying to create in 3D .I can make two straight prongs with no problem, but I can’t figure out how to get them to twist around each other as they are in the picture. It’s important that the two prongs are symmetrical and do not merge into one another where they twist.

I'm trying to do a 3d curve stair rail. I had the 3d spline path, I had the polyline rail profile, but after I sweep the profile, it end up being twisted at the end of the rail. Same problem happens when I did a sweep using a helix path, imagine a vertically placed rectangular profile at one end of the path then after using sweep command, the other end was somehow twisted on a certain degree. How can I avoid this twisting problem
See the before and after image. I wanted the rectangle profile to remain vertical throughout the whole sweep

I had IT install our network version of IV 2012. That seemed to install flawlessly. I still have IV 2011 on my machine IV 2011 and will be running it for the time being.
My problem is when I try to get the iProperties I get this error. "Plugin not available or not properly installed. Notify the System Administrator that the installation is incomplete. DTCP"
We tried to repair/reinstall 2011 and then removed it and reinstalled, to no avail. I have not tried 2012 yet, as all our files need to be migrated to 2012.

I have the student version of Inventor 2014 installed on my computer. My O/S is Windows 7 Ultimate 64 bit. I have installed and reinstalled Microsoft Visual Basics three times. But, I am still getting the error "VBA failed to initialize properly".The program was working fine for about a week with no errors reported. Now, every time I try to start a tutorial I get this error.

I am using Inventor 2009 professional and I have to run a stress analysis on a beam. I put the constraints and the forces I need and when I hit the calculate button, the results so up, but when I click on the results, nothing appears. I need to run this calculation and do not want to resort to hand calculations.

In the attached part if I change the value of the length parameter from 19" to 20" Work Axis 1 updates to the 19" location, if I change it back from 20" to 19" it goes to the 20" position.
In the images below, the axis should be in the center of that last slot.

I am trying to link to parameters in sub-components of an assembly, and feed dimensions to them. When I am in my iLogic interface I browse to the the part in the assembly and click the plus sign next to the part I am interested in. I then click the "User Parameters" section under that part and find the parameter I want to change. Now the normal workflow is to double click the parameter and it shows up in your iLogic code like here in this example:
Parameter("MSS_Cabinet1_Frame:1", "Splice_Length2") = Cab1_SpliceLength2
Well when I try to do this now, I get this:
MSS_Cabinet1_Frame.iam.Splice_Length2
So obviously something got messed up in my machine and iLogic is no longer formating the code properly. It only happens on my machine here, everyone else in our department still works fine. I have also determined that it is happening on all files new and old.
My fear right now is that I may have to re-install Inventor and I do not want to have to do that. I do have a call in with tech support through my local reseller, but who knows how long that will take.

I am working on creating a male mold for a canoe. I first designed the cross sections for the canoe and then began converting them to the mold cross sections. When I try to loft the cross sections I have converted so far, they all loft as I intended until I get to the rear of the canoe (sketch 8). The issue typically arises in gunwale section (the part that appears to be a notch in the sides). Everytime I loft, one of the gunwales splits/twists in an undesired fashion (in the image below the right gunwale is incorrectly twisted).
I do not understand why this is happening for a few reason:
1. The canoe cross sections lofted as planned, and I only added simple boxy shapes to those cross sections.
2. Each cross section is symmetrical (or at least from what I can tell they are).
3. The cross sections that are lofting improperly all have the same number of segments and are in very similar shapes.
I have attached the file of the cross sections and another file of an improper loft.

I have created a SketchLine entity and trying to add aligned dimension by calling DimensionConstraints::AddTwoPointDistance(). It adds the dimension with inside arrowhead (see attached CurrentWorking.jpg), however, it would be nice if the dimension is added with outside arrowhead (see attached Expected.jpg).
if there is any API to toggle the dimension arrowhead accordingly.

I am having to model a spiral slide in sections, and the top piece has this weird angled lip where the opening distorts. Im simply trying to take the face of the extruded part (in three sections) and loft it to the sketch on a different plane. And use the sketched curve as the centerline.

I'm having problems with the crop feature in an Inventor idw. Having cropped my view I then go into the browser to edit the crop (edit sketch), the lines on the crop window will not move and I am unable to edit the selection, why is this not working ? Occasionaly I can move / resize one or two of the crop boundry lines but never all of them.

I have an assignment in school in which we are going to calculate the number of needed rivets and their dimensions to join two pieces of aluminum with the dimensions 5x50x200mm together.
I've created the sheet metal and imported two of them into an assembly along with 8 rivets from the content center with the appropiete dimensions. In comes my problem. I planned on running a stress analysis and pasting the pictures of the results in my report. However, I have a feeling that the stress analysis tool isn't working as it should.
No matter what force I'm applying to the sheet metals, and no matter what material I assign to the different parts, including the rivets, the results, the deformation and force applied to the rivets, are roughly the same.
I've applied a force of 12700N to the two short sides of the sheet metals:
The two sheet metals are also fixed on the opposite side of the forces:

If Inventor is on the screen when the pc locks (win+L) Inventor will not display properly after unocking the pc. Moving the mouse around will change what is highlighted in the feature tree and things like that, but I cannot at all see the actual object I am working on. Changing from one open component to another does not work. I have to restart each time this happens. I have updated both Inventor and my display drivers to a supported version.

how do you get the scale to show up properly in the title block? I've been searching and finding nothing on this issue, with exception of Autodesk personnel telling users to use the scale display on the views. I know it's not the "Autodesk way" of doing things, but my company has been putting the main view scale in the title block for over 30 years.
I've been using Patrick de Stobbeleir's "iProperty Collection" utility since Inv11, and it does the job. The thing that bugs me, though, is that I can't figure out how to get the FirstViewScale:x custom properties to work intelligently in my title blocks. I just use the property FirstViewScale in my title block, which displays the scale of the first view put down...no matter what the sheet.
how I can use the FirstViewScale:x property in title blocks such that x is the sheet number? So far we just have the first sheet use the FirstViewScale, and then subsequent sheets use a prompted entry (I know it's an ugly work-around).

I was working with ilogic, Adding a new rule and all of a sudden I got an error and when I double click on a parameter to add it to the code, the format changed.
It used to look like this when I added a parameter: Parameter("vertical seperation:1", "partitionthickness")
but now when I double click on a parameter I get this: vertical seperation.ipt.partitionthickness
Also when I right click on a parameter and select display current state, It does the same thing, for some reason the code does not display like it used to.
I got an error when this first happened and I tried reproduce the error again but it did not appear again. This affected all my parts and even in different projects.
I re installed inventor because I thought there might be a file link broken but it did not fix it.

When I paste an item in the assembly, the item is thrown off in space. It places it so far away that it is not even in the view window. I have to stop what I doing, do a find in window and then drag it close to where I need it. Then I can start constraining it.
Why does it not place the item at my coursor location like it used to?
I am using SP1.
