AutoCAD Inventor :: Sheet Metal From Flat Sheet To Rolled Part?
Sep 12, 2013
A collegue asked me about this as he has been given a part to model and the details are for the flat sheet not the finished model. Is this possible in 'sheet metal'? I had a quick play but couldn't work it out. Im used to creating the finished part and 'un-folding' to get the flat pattern.Detail supplied below.
Part of my job is to lay out blanks of 3D models so the blank can be sent out and cut. Is there a way to convert an Inventor ipt file to a flat blank? I have tried "convert to Sheet Metal" but Inventor reads the pre-bent part as the flat layout. I am currently using Inventor 2013. i attached a drawing for an example.
I Am trying to make a flat of this attached part. The dimensions are correct for the part but I am trying to make it such a way that I can form it using a die with a press break. I tried many different ways but inventor doesn't seem to allow me to create a lofted flance using a 3-D profile sketch. How to get this part modeled as a sheet metal and have a right flat pattern?
I have a sheet metal IPT that I saved, then did a saveas and saved as a different file name. I then took the part in the new IPT and did a mirror on the part. I chose the second "Mirror a Solid" option in the mirror dialog box, and clicked "Remove Original". Now that I'm at this part, when I try to make a flat patten of the new mirrored part, all I get are the bend and center lines of the part, not the internal and external lines that I can export for use in water/laser cutting.
I was wondering if I was doing something wrong in order to make this work. In looking through the forums I have seen people say not to use the mirror command in an assembly and create a derived part because that has issues, but I did this in an IPT, not an IAM. I have also read to make sure that the Sheet Metal Defaults are set the same, but I believe that they are talking about the derived part from an IAM drawing. All the same, I have checked my Sheet Metal Defaults and they are all the same, and in fact I tried updating them to see if it would still change the part, and it did. I was able to make my part other thicknesses and it updates the part as per the norm.
I am using Inventor 2013 Professional, if it matters at all. I have also attached a couple of picture files showing the part folded and how it looks to me when I go to the flat pattern.
I'm attempting to create a mini version of a product, I use the Derived Component button and scale the part down. Then I use Convert to Sheet Metal, set my sheet metal defaults, but then nothing happens when i try to create flat pattern. Is it even possible to derive a flat pattern from a scaled part?
The company I work for has a large number of Left Hand and Right Hand sheet metal parts. To reduce the amount of time needed to create both Left Hand and Right Hand sheet metal parts, I use the Derived Part icon. I create a Left Hand part, use the derive icon with mirroring on and create the Right Hand part. While the Right Hand sheet metal part gets created, the Right Hand part will not allow me to create a Flat Pattern.
what steps must I follow to create a derived sheet metal part that I can make a Flat Pattern with?
I created a sheet metal part with multi-edge flanges; the part unfolded no problem. Now, I need an exact, mirrored copy of that part [new part number]. My first attempt was a mirrored component at the assembly level. The part was mirrored but it would not unfold. My next attempt was a derived part with the mirrored option selected. This part, too, was mirrored but would not unfold either.
"In sheet metal parts, mirroring flanges or contour flanges created using multi-edge select is not supported." Is this why the flat pattern fails?
Is there a workaround? I'd hate to create the mirrored part from scratch when I all need is reverse bends.
I am trying to program the view placement of various parts and have run into a situation where I need to place flat patterns. On the programming side there isn't an issue, but the issue occurs when attempting to select the wanted view orientattion.
Attached you will find 2 screen shots. One of them is from the "Folded Model" (Take note of the View Cube)
The other is from only Pressing the "Go to Flat Pattern" Button and being in "Flat Pattern" viewing mode (Note the Cube)
I need the Flat Pattern View to correspond with the Orientation of the Folded Model.
I am trying to use the sheet metal functionality to generate a flat pattern of insulation that is wrapped around a tank. The insulation essentially consists of a rolled cylinder with tabs at the cylinder ends that are to be folded inward to cover the end plates. I can't seem to find a way to make this happen as every time I am able to generate the tabs in the folded model they don't unfold into the flat pattern.
I have attached a small Sheetmetal I-Part that is fairly representative of a lot of the work we wish to accomplish using Inventor. Stepping through the table and activating each row therein changes the model smoothly and there are no errors. But as soon as I create a flat pattern for ANY of the rows, I get the error message shown in the first of the attached JPEG images. When I choose Accept, Inventor creates the Flat Pattern, but there are no errors that I can discover (see 2nd JPEG), not even when I expand all the children.
Now that a Flat Pattern exists, activating other rows of the Table result in the error message each time. Delete the Flat Pattern and stepping through the Table returns no errors at all. The folded part is robust and the flat patterns have no interferences or obvious errors.
I have an issue with flat layouts, when a draw a round object such as a rolled punched plate it would be nice to have the flat layout show what the hole callout and spacing would be, however with the way i draw the model. the holes come out as an ellipse, attached is a document showing how i drew the model.
I am trying to design a welded Iron tank whose caps are made of sections, then welded together. I made one section using Contour Roll on Sheet Metal, and worked fine, but when I made the Flat Pattern it mades a square.
I have a simple sheet metal part that does not require explicit bend radii. We leave it up to the shop to fab this part up as long as it's final outcome is within tolerance. We don't normally include a flat pattern, simply because it could cause confusion when cutting a blank. I use the default bend allowance and bend radius, which gives the exact blank size and bend locations. But our local fab shop probably doesn't/won't use the correct tooling to provide the exact bend radius, so this will throw off the final outcome if the blank was cut using the flat pattern dimensions.
I can apply the flat pattern to my drawings, because there is some sheet metal components we have that require the flat pattern to show cut profile features.
I'm attempting to use a macro in Inventor 2013 I found on the Mod The Machine blog to lay out the parts of an assembly. They're wood (not sheet metal), and the purpose is to create a drawing/cutlist with flat views of all the parts for easier DXF extraction.
The issue is that not all the parts in our assemblies are created with the length and width on the XY plane. So, some parts are laid flat on the XY and some stand up straight. How do I modify this code to look at the XZ and YZ planes as well for length and width?
After having a formed sheet metal part finish the wrong size (.100" long on all sides), I discovered a glitch with the sheet metal flat patterns sizes being.
I created two identical parts, one in IV2013 and one in IVP2014, and came up with two different flat patterns. The two parts are 100% identical. The volume is identical for both, and I did an assembly overlay to double check (everything lined up perfect). However, the flat pattern on the IV2014 part was 0.130" shy of what it should be (total length in both directions).
I haven't been able to recreate this (happened with this part and with a different part that we had formed), but you shouldn't ever have to worry about something like this. I created the same part in 2014 for a second time from scratch and it then came out to the correct dimensions, which worries me even more that this is an intermittent problem.
The JUNK file is the one with the incorrect length.
Also, another IVP2014 issue I have been having is when saving a drawing as an AutoCAD drawing it saves it as a 2013 AutoCAD in a zip file instead of a 2007 as a normal file like I have it set up to. If I click "Options" when saving, then click cancel without selecting anything, it saves it correctly.
I am working on a new iLogic rule that will create and IDW with automate views of the folded model of the sheet metal part in front view, right view, top view and the flat pattern I have success with all views except the flat pattern view creation codes. Does anyoone have knowledge of what the code terminology is to add a flat pattern view through ilogic to an idw?
Also, if this is possible, I want to create a bend table and a hole table using ilogic to automate these processes.
So far, I can create any view off the folded model but I do not know the code to create a flat pattern view.
I'm drawing a sheet metal part with several flanges and corner seam, but when I try to generate its flat pattern, the part is not competely unfolded, every corner with a seam is not flattened (while there is a clearance between the corner edges; i.e. no welding)
is there anyway to generate a complete flat pattern without removing the corner seams ??
(the flat pattern is attached where you can notice some flanges are flattened while others are not !)
I want to create a flat pattern of a sheet metal-part that I've used in an assembly. In this assembly I've made cut-outs in some of the parts (see attached .png). Is it possible to get at flat pattern of the specific parts with the cutouts? I can e-mail a ZIP-file with the assembly (the file was too large too attach).
Where I work we do a lot of plate and punch holes in beams for rebar. Is there a way to pull the flat patteren layout of sheet metal and convert to an NC1 file. I can export to a DXF but then i must manually go in and make changes to the DXF in order for it to cut right on our plasma and laser tables. As far as punching holes and cutting beams any clues on this either? We were outsourcing our drafting work before but now we are switching over to in house. I have contacted our supplier of plate nesting software and it looks like they sell something but that means another license of it on another computer.
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.
I set up our company log which gets embossed on most parts as a sketch block in an .ipt. The .ipt contains nothing but the sketch block. To use it, the designer only needs to derive the Logo.ipt file into their part and then use the scale setting to set the derived block to the desired size for that part. The result is a scalable set of line geometry that can easily be used for extrusion or emboss that is standard for all users. It works beautifully, that is until you try to use it in a sheet metal part in 2012.
For some reason, when this same part, which works perfectly in normal parts, is derived into a sheet metal part an error pops up stating that, "Selected part does not have any geometry that can be derived." Say what?
I was able to find a workaround by directly copying the block into the sheet metal part, but you no longer have the ability to go back and scale it if needed. Even more strange, when the block was copied over, it could not be deleted from the new part.
Is this just a bug with 2012? Why does it work in a normal part but not sheet metal?
