AutoCAD Inventor :: Flat Pattern Not Working With Loft / Sweep Feature
Oct 10, 2009
Following on from my post regarding a sheet metal component that was unable to create a flat pattern due to creating the component in an assembly; URL....I have found out that it wasn't the in place component that was the problem it seems to be the loft and sweep feature that cause this problem. I have thought about using the extrude feature (as this works) to create the shape and then cutting the ends to get the angles I want but that would be time consuming.
I have set up the sheet metal rule to be 3mm mild steel, any way creating this component and being able to create a flat pattern.
I work at a car seat company, and we are just now, starting to draw in Inventor. I have problems drawing the seat belt. Here is my first try:
I have tampered with this one! From this angle it looks ok, but it isn't right. I have tried using Loft and Sweep, but with no good results! The seat belt is static in the shown position, but should be able to adjust onto another seat.
I am trying to export geometry found in a flat pattern sketch overlaid onto the flat pattern.
Since I am creating the output file manually I gather the flat pattern boundaries and bend center lines for output to a file.
When I add flat pattern sketch entities to the mix they do not overlay properly. What matrix would I have to push the sketch entities through to get them to the same coordinates as the flat pattern?
I am having a difficult time centered the helical path (the equation curve) and lofting the two profiles (centered) through the helical path in the axial rotation direction..
I made this part, which is a loft consisting of five symmetric squares. I plan on laser cutting each side, which would be exactly the same.
I can't seem to figure out how to make a flat projection of one of the sides. I have tried in sheet metal, but I don't use that feature in my line of work.
The rotor is composed of cylinder and a solid lofted between two 3D profiles. The attached part file is correct. To reproduce the error- change the "inlet_width" parameter from 12mm to 10mm or less (it is a parameter in "Blade Profile" sketch). On updating the part there will be infinitesimally thin solid layer on outer diameter of the cylinder.
-3D Sketch profile is a projection not from the "Blade Profile" sketch, but from a plane offset from it. This was first attempt at a fix. I suspected the original tangent work plane to intersect the cylinder.
-Creating a new solid body from loft was the only way to avoid errors such as "non-manifold solid".
I will be creating multiple versions of this part and I need to be able to safely adjust the "inlet_width" and "outlet_width" parameters. I will be grateful of any proposed fixes/workarounds to that glitched behaviour.
I can't find a way to create multi flat patters in one part from a lofted sheetmetal part. Also, didn't the developers fix the 'can't make a flat pattern from a derived part'?

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?
My next challenge with my rolled cone bottom is to place an oval in the cone that will give the right edges for the lazer pattern. If I create the cut while in the formed shape the edges are not perpendicular to the face in the flat pattern. If I place the cut in the flat pattern, it is suppressed when the part is returned to the formed state.
In other packages I would unfold the part, place the cut, and then refold it retaining the cut. How do we deal with this situation here?
I want to make dxf files from a flatpattern with ApprenticeServer in a VB6 project. I tried this code but I get a Error 5 on the line :
oDataIO.WriteDataToFile sOut, strFilenaam
What's wrong?
Public Sub Maak_UitslagDXF_Appr(strFilenaam As String) Dim oApprenticeServerApp As New ApprenticeServerComponent Dim oPartdoc As ApprenticeServerDocument Set oPartdoc = oApprenticeServerApp.Open(strFilenaam)
I am following the U-Tube exercise called "Emergency Light (Cabinet) volume 1". I am at time stamp 1 hour 26 minutes, exactly.
In the video they use a Loft command in order to cut a shape out of two sketches numbered 10 & 11. I have been copying exactly and am having difficulty at this stage of the model.
Is there any reason why I am managing to use the Loft command earlier perfectly but not at this point.
It's my first time using sheet metal in a drawing and I can't figure out how to show flat pattern in the drawing. When I insert the base view into my drawing, the bottom to "Sheet Metal View" to "Flat Pattern" is shown, but it's ghosted out so I can't select it. Is there something I have to do in the part drawing in order to activate this feature?
So, I have an assembly with a sheet metal part and a lot of pressed studs, spacers, weld nuts. I'd like to do a flat pattern with these parts in it in order to give their positions to manufacture, because they have to be pressed and weld in flat pattern phase, before bending.
Is there any easy way to do this (instead of saving flat pattern as SAT and insert every components again)?
I have designed a hopper using the lofted flange command. It is a 24" sq going to an 8" diameter. I would like to apply the rip feature to make (4) separate sections for this hopper so that (4) separate pieces can be cut on a waterjet machine. I can make it so that only (2) flat patterns are required, (2) pieces cut for each.
Can this be done in Inventor 2011? Also, can you recommend a good book on Sheetmetal in Inventor?
I am trying to develop a macro that exports all flat patterns for sheet metal components. I haven't been able to get the following code to work. It give the error message "The document you are trying to save is not a drawing document"

I just got around to installing my subscription upgrade from INV PRO 2012 to 2013. I am having trouble getting sheet metal flats to show up in the idw's. The folded parts are visible, solid parts are visible, etc. The problem seems to be specific to flat patterns. I have attached a screen shot of a sample part.
When I hover the mouse over where the flat pattern should be, the red dashed box which usually encloses the view shows up, however it is tiny. Barely the size of the view label.
I'm having difficulty with a sheet metal part creating a flat pattern for it. The shape is an ellipse with the dimensions shown in the second picture. When I attempt to create a flat pattern it just shows the side of the part. The sheet metal defaults are correct for the part and it was ripped to created a base point for the pattern. I need to create a DXF for manufacture. I would just use the flat pattern it gives me and mirror it twice to create a pattern but it doesn't factor in the radius of the part. How to create a correct flat pattern for this item?
I was wondering if there is any possible way to flat pattern a coil. Attached is a picture of what I am trying to flat pattern. Its a quarter turn of a full coil.
I want to creat a flatpattern of an iregulary cut cylinder that was made in the standard .ipt world and is now converted into a sheetmetal. I want to "Unroll" the piece out so can see the shape of it as a flat piece. Picture of it is attached.
Any way of drawing an edge bend on a flat bit of copper so I can flat pattern it for the guys on the shop floor to make.
The problem comes with the edge bend, I have provided a picture of a simple bit of copper with various flat bends and a single edge bend. As the flat pattern shows to the right the edge bend is not flattered, This was drawn using a sketch the profile then using "face" . This is why I assume it does not work in flat pattern.
Is it possible to draw an edge bend with a command to allow it to flat pattern? if so which command and how?
I attached the iLogic code which is automatically creating dwg drawing (script borrowed from one of the discussion group users), also it creates 4 views. I`m just wondering how to add flat pattern ?
I am trying to write an external iLogic rule that will export the unfolded model of a sheet metal part in a drawing from a rule triggered in the .idw. These drawings will contain only one model reference. The reason for doing this from the drawing are as follows:
1) The location of the resulting .stp file must be the same directory as the .idw file. our file structure does not co-locate these files so the drawing path is required to locate the .stp file.
2) The current Drawing Rev level is to appended to the .stp file name. We do not populate the Rev iProperty in the part.
I have scabbed together some code from verious deep dark corners on the internet and Have arrived at the code posted below, but It errors during the .stp file creation with the following:
Error Message:
Error in rule: STEP Export With Rev, in document: 4000401-02 Blank Pattern.idw Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL))
