AutoCAD Inventor :: Derived Weldment Changes To 2 Solid Bodies
Apr 24, 2012
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.
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?
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?
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.
Is there a way to get that long tube and that rectangular part all around that middle circle.

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.
Any way to suppress entire bodies in a multiple solid body part, using iPart, without having to suppress each individual feature for it. I am on Inventor 2013.
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)
So i draw a body (or assembly) and i would like to invert what i draw ( tubing for fluid flow) to be hollow and make the hollow part solid, is there any way that i could do that?
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 have a medium sized assembly that I was working with. I decided I needed to create a weldment, so I stripped the assembly of all subassemblies, individual parts, etc and saved it as a different name. However, Inventor will not allow me to convert it to a weldment. That optoin is greyed out.
The only thing I can think of is I have a base part that I have hidden. It is used to drive the assembly. Perhaps that is causing a problem, but I cannot remove it or all associativity will be lost. I deleted it temporarily to try, but did not save it. The convert to weldment option did not appear after I deleted it.
I'm trying to model plug welds in IV2014. I've read all the posts here that say that I need to split the hole faces. Problem is, the split face command doesn't seem to appear in weldments. I want to make the holes to be plugged as a weld preparation. Am I just missing something here, or is IV so backward that a common weld can only be achieved when not working with a weldment?

I just was upgraded to Inventor 2014. I've got an assembly that I want to convert into a weldment. The "Convert to Weldment" icon doesn't appear where it used to be in 2013. I cannot find a way to make it pop up. Is it no longer possible to use this button to convert a an assembly into a weldment?
I started my project, the design is basically a bulkhead chassis design with multiple access panels on all 3 sides. I wanted all of the hole patterns on this assembly to be based on one sketch. So I created a base part inside the assembly, this part compiled of sketches and the sketches compiled of construct lines and points (for panel and chassis fastener hole patterns). This was going great, after learning a couple tricks.
Manufactuing had determined that I need to machine the holes on the chassis after welding. Which means I need to move the adaptive features, from the part files, to the assembly file.
So here is my problem, assembly sketchs are not adaptable? Either projecting to (from that base part file), or projecting from (from the assembly sketch to the part file). I tried both. How I should model this? How do I make weldment machining adaptive?
(Inventor 2012) I have a weldment. I can make holes and save, I can make revolved cuts and save. I can make chamfers and/or fillets and save. But if I try to extrude a cut (any cut), I receive an error.

Is it possible to export a weldment and include the weld volumes? I'm attempting to export to an .stl file and the welds are missing in the resultant file. (Or am I doing something wrong?) The weldment was converted from a standard assembly file, but the BoM structure was set to Normal, not Inseparable.
I have a weldment which includes a sheet metal part called sPart. I want to show a detail of the flat pattern of sPart on the weldment drawing and still be able to balloon the flat as the part of the weldment. So I clicked to add base view and selected sPart from the Preparation dropdown list under the Model State tab of the Drawing View dialog box. The problem is I cannot find an option for using the parts flat pattern.
My design consists of two steel rails that are welded together on top of a guardrail system. To allow the weld to be added between the steel rails I have converted my assembly file to a weldment.
My question is now I have this converted assembly with it's weld in the design can this still be used to perform stress analysis on ? I am not sure the need for assembly to be converted to allow a weld to be added.
What might cause some parts to retain there weld prep chamfers in the part file & other parts don't show the chamfers except in the assembly like an assembly feature?
I noticed that when parts were in a pattern & Weld Prep/chamfered, they retained the chamfer feature in the part.
I'm really struggling with constraining a weldment assembly. I've attached a JPG of the Assembly but I cant get the constrains to go where I want them.
Basically this assembly is a wheel with three equally spaced stays welded to a large nut hub. I have constrained the center axis of the wheel to the center axis of the Nut so the wheel and nut will remain aligned.
What I'm struggling with is constraining the three stays to the wheel and to the nut equally spaced around the nut.
