AutoCAD Inventor :: Way To Make Parametric Assembly
Jan 5, 2012
find out a way to make some sort of parametric assembly.
Where I work, we make conveyors and those conveyors need legs. Those legs are all built the same except for the height and width. They are made of 2 tubes with a cross shaft between them + bolts, washer, plastic end cap.Is it possible to create some sort of iassembly or ipart for this? When creating a conveyor I would like to choose the height and width of those legs when I import them into the assembly.

I am currently working on a parametric assembly using i Logic to control the size of the components as well as patterns. However, I have hit a road block in trying to figure out how to write a rule for resizing the last roof sheet in this assembly pictured below to be even with the frame. The rule below is what controls the roof sheet pattern based on the frame length. The problem I am continually running into is how do you modify a part which is in an element within the pattern without having it affect the rest of the parts in the pattern since they all refer to part. I can get since it is hard to find information on i Logic.
Roof_Pattern_Spacing = Roof_Sheet_Width
Roof_Pattern_Count=Ceil(Parameter("Length")/Parameter("Sheet Metal Roof Section:1", "Roof_Sheet_Width"))
(Note: The red line symbolizes where I would like to have the roof sheet end.)

I have created a parametric, multibody master part file to derive parts from it, and then put them in an assembly. See attached file. Now, I need 3 different versions of this setup (with different values of the parameter 'bending_angle').
What is the best way to do it? If I derive parts from it, they always follow the *actual* status of their master file. Is there some method to do this: "derive from this file, with parameter bending_angle=55deg", but keep the dependency relation, i.e. if I modify something on the master file, the derived part fill follow the modifications (with the value of bending_angle=55deg)

My assembly has grown (about 50 parts) to where I need to consolodate some parts into subassemblies for reuse and alternate iterations of the basic design.
When I import the original parts into a new assembly, all of the constrains I created are not there of course.
I've tried creating a new empty part and then deriving a new part from the assembly, but I can't add, delete or edit any parts.
I looked at using Shrinkwrap, Substitutes, iParts, Multi-body Parts, and Multiple Solids but I remain confused.
In retrospect, maybe I should have created the subassemblies between the part and assembly stage but I didn't.

I have an assembly (ex: test1.iam) that have many parts.
There are 2 of them, that I what to make only one assembly, and I would like them to stay in same the position as in test1.iam.
How do I do that?

what kind of work flow I can use to make an assembly adaptive as possible..I need to make a machine fixture that requires cut outs for three parts. The fixture is made from a 8" x 5" x 0.19" thk piece of UHMW. I've made the "blank" and it features the work planes I need to place the three parts that the cut outs are derived from.
At first I just started the assembly and placed the parts where they should be and then used sketched outlines to define the cuts. However, since the parts are there they get "cut" as well.
I was wondering if I could make adaptive sketches linked to these parts and then import THEM into the correct plane. I could then use them to define the cuts.

I have the Silicon crystal (as attached herewith along with he parts and the assembly). It is a simple and small structure which I created from 3D Cartesian coordinates. Now, I need to repeat this structure in X Y plane to make a bigger structure.

I have an assembly that includes iPart.
For example there are:
C: Part1
C: Part1 Part1-01
C: Part1 Part1-02 ...
C: Part2
C: Part2 Part2-01
C: Part2 Part2-02 ...
I need a macro to make the change in the assembly. You need to replace Part1-04 to Part2-04. Which method should apply for this?

Is there a way to have inventor make each part in an assembly have a different color? I like to work in assemblies like this because it is easier to tell the parts from each other. It's just time-consuming to go through and change everything if the assembly was designed with realistic colors. I am thinking there might be a macro for this, but I don't have much experience with macros so idk.
(extra brownie points if the method has the capability of reverting back to realistic colors)

I have a sketch on a component. That component is being used in an assembly. The assembly drawing (.idw) does not show the sketch on that component. I have made them visible on the component, but don't want it visible on the assembly model. (only the assembly drawing)

When I double-click on a component in an assembly to edit it, the rest of the assembly becomes transparent (or translucent is a more accurate term). Is there a way to create a visual style (or use some other method) to make the entire assembly translucent like this, just as I'm working with the assembly performing all the usual assembly-type operations? For example, I can operate under the "Shaded" visual style, or the "Wireframe" visual style, or the "Monochrome" visual style.
Is there some way to work with a "Translucent" visual style so that I can see the internals of my assembly as I'm placing parts, applying constraints, etc.?

I'm trying to find the most elegant (okay... any) way of making a simple half lap joint. Basically I just want it to update based on a thickness parameter or when the sketches update.

I'm having a really difficult time maintaining my parameters when making changes to the part I've made in the attachment. The control parameters for this part are:
-100 mm distance between 15mm circles
-1 of the 15 mm holes
-30 mm hole
I am new to inventor but I would also like to be able to set up my constraints correctly. I'm also not sure if my sketches are ideal for this part either. I usually get an error concerning my fillets from the base to the center support beam when I try to change the 100 to 75.

I have a big assembly. It used to have aprox 280kB.
I have created the five flexible assemblies and it grew up to 2100KB and became
quite slow even with a lot of supressed parts.
The question is: should I blame the flexible stuff for this slowup?

I have a parametric assembly and some of the parts in this assembly require a "Break". When the part dramatically reduces in size the part view disappears as the part is now located in the "Break". Delete the "Break", re apply the "Break".
I would like to be able to constrain a Break to the part, either a sketch on the view or maybe from Workplanes in the part.

We are a transport engineering firm in Queensland and I would like to develop a spreadsheet that can formulate cross member distances and recalculate to add or remove cross members.
The basis of this is the overall size of the body we are building.
For example: The maximum width of a body in Australia is 2.5metres overall. Our cross members would be 6 mm shorter than the overall width of the body to allow for 3mm end caps to cover the open ends of the cross members. So the length of the cross member is width minus 6, or , parametrically the length is (overall width - (endcap thickness x2))
The body length is the tricky one. We have a maximum spacing on the cross members. This will vary from size of body to size of body. EG the spacing on the small 2 tonne body will be different to the spacing on the 12 tonne body etc. So lets say we want to have maximum spacing of 450mm and a minimu spacing of 300mm between centrelines of the cross members. The overall length of the body will also determine the number of cross members required.
On top of this there is the front and rear coaming to take into consideration.
So the formula would be ((overall length - front coaming - rear coaming) divided by cross member spacing)) then a check to see if the last space is what and then can we change the cross member size to take up that space without going over the maximum space. We would also need to take into account the width of the cross member section as well in this calculation.
EG if we have 150mm left at the end we could increase the cross member centres slightly to take up this additional space without going over the maximum space allowable.

I'm trying to make an oil pump from an inventor assembly file. Whenever I import the assembly, 3DS only recognizes the assembly as one object, so I had to import each part. Whenever I try to do a link constraint, it rotates the object in the wrong direction.

I have a part that has protrusions. When i mate that part up to another part that second part needs to have cutouts/holes to receive those protrusions.
i mainly use it in sheetmetal parts. and use the rectangular protrusions on de contour to mate up with corresponding cutouts in the other sheet. this works with positioning and also makes for a nice weld spot/area.
But also for making holes to accommodate a mold pin used in custom punch dies. I want the intervening part to receive a corresponding (propperly tolleranced) hole automatically. Much like a bolted connection does.
same for parts like circlips. i want them to automatically generate the seat in the part it's mated to. Rather than using the axle generator.
Ofcourse one can place the parts and do an in assembly interpart projection and go from there, but i want the part to generate the (predifined) modification to the other part. It would save time and also reduces problems as the parts are moved about or even removed.

I'm looking for the best way to create a separate assembly out of various component parts in an existing assembly so that the whole thing can be placed in an assembly as you would a part, I know it's possible to demote components within an assembly but are there any other methods similar / better ?

We have an iLogic assembly with to parts in it. Maybe to cylindrical parts. The iLogic rules should do the following.
1. Start a Rule after open document.
2. This Rule starts a Rule in the first cylindrical component.
3. This Rule ask the user for a diameter.
4. The assembly gives this new parameter value to the second component
5. Then the assembly calls another rule in the second component to change it with the new parameter
Everything is working fine when the following combinations are taking place:
1. I open up the assembly out of vault or from a local drive or an accessible server drive
2. I insert the assembly as sub assembly in another assembly from a local drive or an accessible server drive
It don't work with the following situation:
- I insert the assembly as sub assembly in another assembly out of vault
Then the user becomes the dialog "Choose a diameter" twice.
I don't know why, but I have the idea it has something to do with the functionality of inventor to insert a component more than once. If you insert a component in an assembly Inventor gives you the opportunity to add more than one occurence after each other.
change that behaviour? Maybe a switch to change that inventor "add more than one occurence" behaviour.

I have encountered a problem with the Tube and Pipe styles.
As you can see, I have a rack assembly with a custom tube and pipe style. A wire as a tube in orange, and a tube support in white. Both have their seperate colorations at a style in the tube and pipe styles editor
When placing the rack assembly into the main assembly, it reverts to the coppor coloration I changed from the original style.
Steps I've taken:
Exported the styles .xml and Imported the styles into the master tubeandpipe.iam
Imported the user created .xml styles into the main assembly file nothing seems to work

I am trying to find the interior volume of an assembly (when am I not?!?!) by subtracting the assembly from a block that surrounds the most of it. Somewhere the assembly has a "leak" and I have been trying to use the Cross Section Analysis to track down where the inside lump is connected to the outside lump to be subtracted. Is there a less time consuming way to dynamically drag a plane across and get cross sectional views?
Even better is there a simple way to animate the analysis plane moving across the block so I can hopefully just watch and pause it when I find a leak?

it is possible to make a constraint that utilized a parameter of a part within the assembly.
For example, if I wanted to use the thickness of a plate, which I defined in the part, could I call that parameter in a constraint?

I want to be able to control the location/position of a component in an assembly. This is easy enough through the iProperties/Occurrence tab and then adjust the location of the X,Y, and Z offsets. Is this possible using iLogic? I have been unable to find a function to access via iLogic. Ultimately I am trying to translate a component about an axis not a pattern.

I have a two part duct fire damper assembly. The IDW has the combined two part assembly, which I know how to turn the CoG on, so that it can be dimensioned. The problem is each piece will more than likely be hoisted separately so I would like to show the CoG for each piece, not the combined master assy.is there a way to do this?

I would like to see if there is a routine that allows my iLogic code to detect if my assembly contains another assembly within it. If my assebly contains assemblies then I don't want "MyRule" to run. Else if it does then I want "MyRule" to run.

My Assembly has two possible positions for my piston.
I would like to show both piston positions (top and bottom) in one drawing file; however, in different drawing views.
I have tried using LOD and Drawing View Representations, but it is my understanding that neither of these are meant to be used in this way.
