AutoCAD Inventor :: Using Parameters To Control Pattern Features?
Jul 22, 2013
I have entered in all the available sizes and have the outer frame of the louver adjusting nicely.Now where I am running into trouble is setting up the louvers and the louver spacing. I have been playing around with the parameters for awhile now and I just can't wrap my head around some things.
Example one:
in the picture below,
HEIGHT is selected on 18 in
I have created an user parameter called LOUVER_QTY which is set to subtract 1.6 in off HEIGHT = 16.4, then I divide that by 2.05 and the result is supposed to equal 8 but it is showing 3.149606. But when I assign LOUVER = LOUVER_QTY it is showing 8
For the most part this file works fine, but when the Height is changed to 56 in, the last bottom louver runs through the bottom of the frame.
I know that I have to change the spacing from a direct input (2.05) to a equation based on height to fix the spacing, but I can't grasp how these parameters are working, why are they red(errors)
Also I don't know how to set up the parameters to set the correct number of occurrences in the rectangular pattern to control the amount of louvers. Something related to to the spacing of the pattern and the selected height.

As you see in the template photo (the photo was scanned by Microsoft Security Essentials, healthy) I wanted to extrude my circle, and I made 28 pieces with circular pattern feature; now, do I have to choose all the pieces by one by to be able to choose all?
The sum of the problem: while using the Circular Pattern feature or rectangular pattern feature in Inventor, sometimes I want to extrude (join) or cut the drawings that I made (augmented) with using circular pattern feature, rectangular pattern feature. in this case do I have to choose all the augmented members one by one (for instance I make 42 augmented members), it can take a lot of time.?

Is there a way to write a set of rules so that I can switch Work Features On and Off via a Text Parameter.I have an assembly made up of a number of parts used hundreds of times within in various sub-assemblies. If I make a particular sub-assembly 'Invisible' then subsequently 'Visible,' all work features that had previously been set to be 'Invisible' are switched to 'Visible' also.
Likewise if I simple want to set a particular Work Features' Visibility in one particular sub-assembly, I would like to be able to do this via a Text Parameter rather than having to laboriously scroll down the Assembly switching the visibility of features on and off.
At the moment if I turn the visibility of say a Work Plane On in a sub-assembly then all sub-assemblies deploying the same part switch the visibility of that Work Plane on too. Hence I cannot see my work for Work Planes.Obviously the Global Switch under View is of no avail,
So I would like to be able to create a Text Parameter for each sub assembly and in turn each Work Feature with a Yes/No Visibility switch controlled via a set of Rules in iLogic.

As my Inventor endeavors continue, I would like to take a template of a part I made and use Excel to change the parts dimensions. Essentially make it so if we need a 20 Tonne Lift Lug, I just punch in the necessary values in Excel and have the part update.

From iLogic i got a lot of information. And i want to configure or display this in a form.
But without having to make parameters for everything.
Example:
Display the stocknumber of an ipart/iassembly.
Configure the parameters from a part in the main assembly.

I have a part made where various parameters in it.
Now I place the part in a assy and from there i want the parameters to control the part.
I do this now by the same parameters from the part to add in the assy by typing the parameters manually in the assy.
Is there a way that you can define parameters retrieved from the part about the assy without retyping and therefore can make mistakes?

My flat pattern of a sheet metal part fails when I added strenthening Press ribs to the middle of the part using an iFeature.
I know Inventor is not capable of flattening embossed sheetmetal but is there a way to still get the flat pattern & ignore the formed areas?
Seems to me I was able to add some model features in the past like bosses, extruded holes KO's etc & I could still make a flat pattern.
I know I can use derived part to do it but that adds complications.

Is there a way to "skip" features i'm creating a pattern by?Meaning, similar to this option in Proe and Solidworks, is it possible to choose some of the holes i'm copying, so they won't be created?

I would like to insert 2 or more of the same subassemblies into an assembly, yet have each subassembly a different size.
When I do this currently when I change the parameter for one of the subassemblies all the subassemblies are changed.

I am trying to control the parameters contained in a part that is not in my assembly. May sound odd, but I am using the multi body part modeling feature to create all of my bodies in a single part file, then making these components/sub assemblies, and pulling them into my assembly. However, I do not want to have the "control part" in my assembly, I just want it to drive the parts. I cannot figure out how to access these parameters without having the part included in the assembly...

I would like to generate a rectangular pattern of extruded tubes which have an internal radius that is proportional to the distance to the centre point of the pattern. Or in other words tubes which are narrower in the centre, and wider at the exterior. Is there a way to do this without resorting to creating each tube individually?
More generally, is there a way to parameterise a feature dimension/parameter so that it is a function of spatial position?

Let's say that I'm making a simple L bracket. I'm going to form it, and machine the holes in both ends *after* forming. So I don't want the holes to show in my flat pattern.
On the few threads I found, the consensus seemed to be that you may have to have the part file contain no holes and put them in as assembly. So I just accepted this that it must not be able to be done.
Then I ran across a piece of promo literature online from AutoDesk that made mention of the ability to create "postform" features that obviously are created after the forming process.

Switched to the flat pattern of my sheetmetal part and created a sketch.
My intention is/was to control the values of the sketch parameter values using ilogic.
I cannot access these parameters through the ilogic parameter interface or the ilogic rule editor.
I am using ilogic with Inventor 2009 / Inventor 2010 Certified Professional

Is there a way to setup Field entry text in a Table that will control Dimensional Constraint Parameters in a model?
I basically want the control of the Parameters Manager to be in table form on the drawing that is usable and printable.

I would like to be able to control the fire rating a door must have through a yes / no parameters. I have created a shared parameter for all the different codes and then I have loaded them into the family, now I just want it to work so that when a rating is checked the name will be in "Fire Rating".
EI0 selected when the door is not fire rated.
As can be seen in the picture, I found out how it can be doneif there are 3 checkboxes.

How can I make a circular pattern of a single occurence of a rectangular pattern?
A shaft has a rectangular pattern of holes (along its axis) on its surface. I want to pattern the 4th occurence of this hole pattern as a circular pattern? Can I do it in Autodesk. I can not select the a specific occurance of a patterned feature to pattern it again.

Is it possible to take a feature created by a pattern and reuse it to create another pattern? I have a circular part on which I have created a linear pattern (using the rectangular pattern feature) of holes, 6 in total listed as 3 ccurrences. if we number the holes 1-6, I would like to make a circular pattern based off holes 2 and 5. I have been unable to figure out how to select the individual "occurrence" related to the hole once in the pattern feature. If I create the circular pattern first and then the linear and try to suppress the others it supresses both holes in the occurrence.

I am creating an assembly with my base part being a weldment. I've added other components that mount to my base part. Now I need to add fasteners to the mating components. I have added my first fastener and now want to pattern the said fastener using the "Pattern Component" and by using the "Feature Pattern Select" option and selecting "Associated Feature Pattern". At this point I have already selected the component that I want to pattern and selected the "Associated Feature Pattern" to select my base pattern. The only problem is that I am unable to select the pattern desired.
A note on how my Weldment was constructed -The holes were created in the "machining" step of the weldment, not in the individual part before it was placed in the weldment assembly.
If I move the hole feature and its pattern to the individual part and then place it in the weldment assembly, I can then create an "Associated Feature Pattern" in my assembly file.Why can I NOT create the associated pattern when my hole features are created in the weldment assembly? Or am I missing something?

I have an assembly which I am using as a icopy component. In the assembly I have the adaptive sketch which os used for the icopy function and a part which is adaptive to the sketch. I then have the part pattern itself in the assembly. The problem is the pattern will not update when changes are made unless I edit the pattern. The pattern references parameters from the sketch so that when the sketch changes the pattern should change. It works but the pattern will not update unless i open the pattern to edit it. Is there a vb function which will force the pattern to update when a change is made? I tried the update document vb functions but no change. I will try to get a sample together that is a smaller file size so you can see what I am talking about.

I want different features on and off with iLogic.
I have a text parameter with a choice menu of 1,2, and 3
This I want some features on and off.
If I pass the parameter I get a message: No feature found with the name. Mvg Jos

when in simulation, if you suppress a feature is it totally taken out of the simulations workings?
I.e. if I was working on a project like some weighing scales and I had a load of objects on the scales and I then suppressed some of the objects, will the scales rise up a little to counteract the reduced weight?

I am working on a standard part that has different configurations depending on user inputs into a GUI. Once the user enters all the required parameters, the part is in its final form with all unnecessary features suppressed. I am looking for a way to automate the delete of the suppressed features using a rule and i Logic before the user saves the file.
The main reason for doing this is to reduce the file size of the part once it is saved because this same template will be used for hundreds of parts and I don't want to waste unnecessary storage space on suppressed features.

I am making a multiview drawing with isometric of a certain sheet metal part. Due to manufacturing reasons, they have to make the part longer than necessary to get a bend in it then I will have them shear off the extra. Is there a way I can show the multiview and flat pattern WITH the extra material and show the isometric WITHOUT that extra? In the model I remove the excess with a cut but I don't know how to suppress a feature for one view and not another.

I am trying to hide an extruded cut in one view of my .idw. I have tried supressing in one view but this does not work. I need to show a before and after of this cut in the same model. I can not make two models because this is a controlled document.

Inventor 2010 / I'm finding myself scrolling up and down the browser bar quite a lot to get to the Solid Bodies folder for example, and I was wondering if it was possible to group features into folders or something to make the journey quicker, with the benefit of also being able to just organize things a bit better.
