AutoCAD Inventor :: Demote Solid Bodies To Sub Assemblies
Dec 5, 2012
I have an assembly file for a fan casing. We reuse this model and scale it up and doen depending on the size of fan.
For transportation we split the caing into several parts and join using flanges. The number and angle of splits changes depending on the job and geometry.
To model this we share a sketch through the parts and use the split solid command to split them.
I would like to able to create sub assemblies from the main assembly so that drawings and masses can be obtained for the sub assemblies. However, the 'Demote' command does not allow you pick individual solids from a multi solid part.
I have tried creating new parts from the split solids but these are not in the correct location as they are not constrained correctly.
Is there a way to use the Demote command as I am proposing? or is there a different method to split my parts?

I'm trying to split a single solid body into 2 solid bodies. The problem is that the body I'm trying to split consists of two separate pieces. I can split a body when it is a single piece no problem, but I'm having the problem when the two pieces are not joined at all.
When I try and split it on the origin plane it gives this error:
"Creating parting line failed. Could not build this Split"
When I try and split it on a work plane lying on one of the pieces it gives this error:
"Creating parting line failed. Modeling failure in ASM. Redefine inputs."
Or, another variation on this erorr:
"Creating parting line failed. Split feature could not create two bodies. Change the Split Tool so that split feature can create two bodies."

I have a model with solid bodies. I have used the combine feature to make cuts outs in some plates. The geometry is complex to model so Extrude cannot be used for cuts.
The body used for the combine can be at different angles and sizes. Due to this some of the combine features will not be needed or have no effect. This leads to the error message:
" The feature as specified did not change the number of faces (and may not have affected the part). Accept the feature that resulted, or use Edit Sketch or Edit Feature to change the feature definition." Is there anyway to suppress this feature automatically using i Logic?

Is it possible, via VB, to modify solidbodies color ?
Actually, I need to modify part color. But in some cases, the part color and the solidbody color are not the same. So I need to modify the Solidbody color, to match the part color.
I found the bodies in ComponentDefinition.SurfaceBodies, but I can't find something like ComponentDefinition.SurfaceBodies.Item(1).color.

Open the attached file 207665-124.ipt. how their is only one Solid Body, but the iam needs to be updated because the user added one more part to the assembly. As soon as it updates now instead of one Solid Body I have 2. I don't want 2 and this is not typical. Even if I derive the 207665-120 into a brand new part file, it is only one body. What is causing this to seperate into 2 bodies? I tried to re-create this from scratch and can't, but he has several files like this that need updates and the 2 bodies causes problems with the holes.

Open this picture. In the end it would end up looking something like that lamp shade. I got one part down so is there a way to get a bunch of those around instead of redrawing it?

I have a pressure vessel which I am trying to analyse. Whenever I convert the solid into 'thin bodies', it loses some of the data. For example, a fillet and a supporting ring (refer to pic attached). I haven't been able to find any 'shell element' settings to adjust.
Also, I need to manually add contacts otherwise the vessel seperates into multiple bodies.
Even though the solid model is in contact, the 'midsurface' shell seperates it. Refer to part file attached.
I briefly tried to run the analysis as a solid model, but gave up as it was taking forever just to mesh.

I'm creating a template part to line the inside of a wall with wall boards. All the boards are drawn as an array of seperate solid bodies which are to be made into components once the windows and appertures have been extruded out.
The problem is when the wall changes to a shorter length and then back again. the solids are re-created and the extrusion e.g. Window1 does not have the new solids in it's effected solids list, so I get an error.
Is there a way to set the extrusions "effected solids" (Not sure if that's the correct term) to all the solids all the time through iLogic or the API?

I have a Hole that cuts through 2 solid bodies, a gasket and a cover plate. I want to pattern the hole in BOTH solids at the same time, but the pattern feature dialog box will only let me select one solid at a time. I could pattern the hole in one solid before projecting to the other, but the quantity of the holes can change. When the quantity of the holes changes only the holes from the initial pattern are projected. For instance if I have 10 hole initially and it increases to 12 the 2 new holes do not project to the second solid body.

I'm trying to do a stress analysis on assembly with a mixture of thin bodies and solid bodies. The problem is that when I create the automatic contacts they are created as either all thin body or all solid body contacts. This of course causes the analysis to fail. It appears that there is no way to make a thin body contact become a solid body contact or vice versa.
I tried to run the entire thing as solid bodies but the I had to stop the analysis after 18 hours of continuous processing. (and a memory upgrade)

I'm currently using the "Make components" feature to convert solid bodies into parts. This works great, but we use this method to construct angular roof structures, and after the parts have been made the parts have angular relationships to the .ipt files UCS co-ordinates. It would be very useful if I could align the longest edge of the part (Which is a timber truss) with the x axis in the model space and "lay" the plank flat on the X-Y plane.

I've created an assembly by using "Make Components" from a part comprised of solid bodies. If I suppress a feature in the "Control Part.ipt" (the part that holds all the solid bodies) it removed the part from the assembly, but it does not remove it from the BOM. What do I have to do to make the BOM follow what the assembly looks like?

We are going from Solid Works to Inventor as our main CAD program and will be converting files to .ipt and .i am. We are moving our file structure into the vault as it is, with some commonly-used components in their own folders. When I convert an assembly, it only grabs the parts that are in the same folder as the assembly. Is there a way to have it look in other folders for components or to have it ask me to locate ones that are not in the assembly folder?

I'm trying to create an ilogic rule that will look within the folders of an assembly and take the contents of each of those folders and demote them to separate sub-assemblies.
ie. Assembly1 contains NewFolder 1. NewFolder 1 contains Part1:1 and Part2:1. Upon executing the ilogic rule, I would like Assembly1 to contain NewFolder 1 and within NewFolder 1, Assembly1-01. Assembly1-01 contains Part1:1 and Part2:1. I would like this ilogic rule to look within each successive folder within Assembly1 and demote them according to their position in the browser such that NewFolder 1 - at the top of the browser list - contains Assembly-01, NewFolder 2 contains Assembly-02, etc.
I currently copy a master assembly with browser folders that contain parts and sub-assemblies to a secondary assembly where I manually demote the contents of the folders to sub-assemblies. When I create a drawing for our machine assembly department, the demoted sub-assemblies to isolate only those parts - nuts, bolts and the pieces they fit to - so it is easier for the assembly department when putting a machine together.
Is it possible, using ilogic, to demote folder contents to sub-assemblies with an assembly document?

I am working in an Inventor Assembly .iam, I have about 250 fasteners (screws) that are constrained to a flat washer and lock washer. I would like to put them in as a single unit (sub assembly if you will) and then promote or explode them in the top level so that my bom has 250 screws, 250 washers, and 250 lock washers all at the same level, not associated to one another except thru the constraints that were entered in the original assembly. I have tried Promote but that doesn't work because it removes the washers from the original file and I end up with only 1 instance of the assembly. Am I approaching this incorrectly? Is there a better way? I run across this scenario with different components quite often.

If you have created a sub assembly and inserted it into an upper level assemby, is there a way to bust up the sub assembly at that level?
The issue arising is the individual components need to be called out on the upper level, but in the drawing are all showing up as the same balloon.

I found a VBA-code on internet which turn off all work features (plane, axis, points) in all documents in an assembly.
I want to modify it so it turns of all surface bodies instead. I use skeleton modelling where i only want to keep the solids visible and not the surfaces. When I run this iLogic rule all solids get turned off instead of surface bodies.
This code works (when edited) for axis, points, planes, allworkfeatures etc.
'catch and skip errorsOn Error Resume Next'define the active assemblyDim oAssyDoc As AssemblyDocumentoAssyDoc = ThisApplication.ActiveDocument 'get user input as True or FalsewfBoolean = InputRadioBox("Turn all Work Features On/Off", "On", "Off", False, "iLogic")'Check all referenced docs Dim oDoc As Inventor.DocumentFor Each oDoc In oAssyDoc.AllReferencedDocuments 'set surface bodies visibility For Each oSurfaceBodies In oDoc.ComponentDefinition.SurfaceBodies oSurfaceBodies.Visible = wfBoolean Next Next'update the filesInventorVb.DocumentUpdate()

I am now modeling elements for silicone formwork for casting elements of epoxy resien.
I would like to schow idea of this formwork. For this I would like to make part representing silicone part of this formwork. It is contained in aluminium "cover" for convenience of use.
In assembly I have placed may model, and aluminium elements representing "cover" of formwork.
I am trying now to model silicon but it is quite hard. I can not use "derivered part" method to substract model and cover elements from some big block body because coordinate systems do not mach in all elements.
In Part there is "combine" function but it only works with bodies mabe within this part.
Is it possible to substract one placed in assembly from anothe part in this assemby?

what I do need clarification on is the statement in this warning "One or more bodies which are thing being treated as solids". Does this mean that the bodies that were detected fall under the criteria for being a Midsurface or Offset and that the user has the opportunity to apply these commands in order to make the analysis more accurate? So if I were to ignore this and continue with my analysis, the members will still be treated as a solid and not as a shell and/or surface (which is what the Midsurface/Offset command produces)? The members I am using that have triggered this warning are HSS 2x2x0.125 x 12' long.

I have been extruding bodies around parts, then using their verticies for the frame generator (to guard around complex machinery.I then suppress the body and am left with the guard frame.
when i go to get the mass for the part, it includes the volume of the solid body which was used to give the outline.how can i turn the material property to zero density?
