AutoCAD Inventor :: How To Model A Sheet Of Corrugated Steel
Jun 12, 2012
I have a question regarding the best way to model a sheet of corrugated steel. I would guess the easiest and quickest method would be to create a profile curve, offset a thickness and extrude this to the desired length. I was wondering how would I go about sketching out an accurate profile curve that could be used to create the form?

I use to work drawing, calculating and budgeting corrugated steel for foundations and I always have the same problem. Once i have desinged and drawn all the lines (or polilines) i have to count every single corrugated steel to know how many of them I have in order to know metters of steel that we have to order to the manufacturer.
any command that autocad has to measure this kind of lines or polilines?how many metters of corrugated steel I have.
I have to design the packaging that goes with the products we make and it occurred to me that sheet metal and corrugated paper behave similarly. And it would be nice to design the packaging around the product and then unfold it to spec the die cut and for estimation.
I had good success making flat patterns for corrugated fiberboard (cardboard commonly used in packaging). I am posting the sheet metal settings here because I didn't find them anywhere else.
This forumla comes from Inventor Reference Guide > Work Environment > Styles and Style Libraries > Work with styles > Linear:
Unfolded length = (inner Bend Radius + KFactor*Thickness)*(Bend Angle)
where bend angle is in radians.For corrugated_fiberboard, let inner Bend Radius = 0 and let KFactor = 1 (no stretch on outside, inside compresses).
Setup "corrugated fiberboard" sheet metal style in the Style Editor: from a sheet metal part, ribbon > Manage > Style Editor > Left pane, Sheet Metal Unfold, Default_KFactor > New > Name: corrugated_fiberboard_KFactor > Unfold Method: Linear, KFactor Value: 1 ul > Left pane, Sheet Metal Rule > Default > New > Name: corrugated_fiberboard > Sheet tab > Unfold Rule: corrugated_fiberboard_KFactor For thickness, refer to [URL] ..... > Bend tab > Bend Radius: .0001 > Save
Before you save Styles to Style Library, make sure your Style Library is Read-Write. Close project files and then from Projects:
Use Style Library = Read-Write
To save a style:
Ribbon > Manage tab > Styles and Standards panel > Save icon > click "Yes to All", OK
Changes made to a style library are not available in other documents until the current Autodesk Inventor session closes and a new session is reopened.To make a fiberboard mock up, print a 1:1 scale drawing, contact cement drawing to fiberboard, cut, fold, and hot glue.
I was wondering the best way to model a steel tensioner cable in Inventor. The assembly I have designed is of a cable fixed between two brackets which are fastened on two structural beams. I am looking accurately model the cable attachment on the brackets. My inital thought would be to extrude the length of cable through a pre-defined path between the bracket fixing holes however this would not represent a 'true life scenario'.
I have automated the changing of the active renderstyle to "Polished Brushed" to approximate this, but usually orientation is important. For instance, the texture will be around tube, and on large sheets, we want to keep all the sections orientated one specific direction.
I'd like to be able to easily rotate the texture thru 90 degrees (and possibly, a user selectable angle).
I'd prefer not to have to manually select a face first, either.
I've generated my steel frame model using a skeletal model technique. So my part file consists of only sketch lines representing where I want my steel to be placed. I've created an assembly and used that in my inventor.dwg file.
The problem is that I need to dimension to the sketch file and not to the model shapes because the sketch lines define the center of gravity. These lines aren't visible even though I've right-clicked on the content and selected "Get Model Sketches". How I can get my skeletal model through to the DWG environment?
I'm familiar with basic solid modelling for walls, roofs etc. but for my project at the moment I have a concrete wall with a number of suspended platforms held up by 45 degree steel tension cables.
I don't know much about curves and pipes and things.
Do you know the easiest way to model a steel tension cable with some form of connecting eyelet at each end. Preferably the cable should look as though formed from twisted wires rather than a smooth rod.
Very thin gauge aluminum sheets with a composite sandwiched between them.
The challenge is, the panels are relatively thick, 3mm or 4mm, but a router is used on the fold lines before bending to cut through all but the outer aluminum. This makes for a very tight bend radius.
So, thick 3 layer material, tight bend with mitered corners. Can Inventor's sheet metal tools handle this?
I am making this 3d Model out of Sheet metal but I am having a problem finishing it. On the very bottom of the part, I want the red and the green surface to be parallel to the Y-axis on both sides. The sketch "Desired Geometry" shows what I am trying to make. I tried using corner seam but it gives me error. The distance between the two red surface can vary. How this shape can be achieved which will give me a correct flat pattern too.
I have a few 3d models of some sheet metal models in AutoCAD. I want to do a software driven flat pattern in order to make repeatable and reliable flat patters in the future.
My firm is starting a project....the Structural side is going to be don in Revit 3d and our Mechanical side uses Autocad w/Cadworxs for our 3d package. Is it possible to export the Revit steel drawing and import that model into Autocad as an xref?
When I use the rip commandment a message appears " for proper folding the model should have uniform thickness equal to the model parameter thickness. Please set the proper thickness in the sheet metal styles to match your model".
I have a piece of steel that I need to flex. It is a piece of blue tempered spring steel pressed against the corner of a brass pressure transfer. The opposite end of the transfer is tangentlly constrained to a latching mechanism. When the latching mechanism is lifted, the transfer rotates slightly around a screw (made invisible) and the spring is flexed. When the latch is released, the spring returns the latch to the closed position. I have several other assemblies that use the same principal, but some with just a piece of mild steel used as a cover as well as a spring.
I got this code below to place a channel in an assembly, but don't know how to change the length of the steel.
' Set a reference to the active assembly document. Dim oDoc As AssemblyDocument oDoc = ThisApplication.ActiveDocument ' Set a reference to the ContentCenter object. Dim oContentCenter As ContentCenter oContentCenter = ThisApplication.ContentCenter ' Get the content node (category) "Structural Shapes:Channels" Dim oContentNode As ContentTreeViewNode [code]..........
We use several different classes of steel such as A572-65 or A572-50 etc. Any way to add those values in Inventor 2014 without having to reinvent the wheel?
I am looking for a material database with more steel types than the ones that are installed in inventor.
Is there a comprehensive database that I can download and install or do I need to add the material one by one.
Normaly I can just copy a existing steel and just use the existing properites and just change the name but I see a risk of this since in the future I may want to simulte a part and then the material data is not correct.
So... is there a good list that I can download and install??
I received a rather large assembly file from a client that was done in Pro E. I was wondering if it is possible to change the entire assembly from Default material to steel without having to go into each individual part and changing its material manually (which could take several hours) I am using INV 2012 Pro with SP1 installed.
I am drawing hydraulic steel pipes using the 3d sketch command. I enter in the points representing the change of direction of the center line of the pipe as if it had no bend radii.
The points are entered in using absolute X,Y,Z coordinates, choosing one end of the pipe as 0,0,0.
I then join the points using the line command. I then put the bend radii on using the bend command.
I then draw a 2d sketch of the 2 circles representing the id , od of the pipe on a normal plane at the start point 0,0,0
I then sweep the 2D sketch along the path of the 3D sketch. I then place axes at the center of each straight portion of pipe . I then place points the intersection points of consecutive axes to replicate the original setting out points (3D x,y,z coordinates) that I used in the 3D sketch.
Then I create my idw with 3 orthographic views (showing the relevant axes as a symbols in each view, an isometric view and a coordinate table showing the x,y,z coordinates of each labelled change of direction. I then pull the pipe into an assembly and put the fittings on each end.
This is another IDW showing the fittings and a parts list. I have inventor suite 2012, along with tube and pipe. However I have never tried it.I don't know how it works, maybe it would be better to use that?
Another question on the measuring of pipes. If a sample is made and then backdraughting needs to be done how do you measure it.
Method used before I arrived was measuring lengths and angles. Highly inaccurate. Never worked. Pipes never drawn. Ended up being photographed only, which was not good enough to make spare parts for service technicians in the field, they had to go out to measure on site and make up on site.
I introduced measuring the change of direction vertices of the centreline of the pipe as if there was not bend radius.
More accurate, but highly difficult to measure. Use steel rules and squares. Never right the first time. Always have to check putting the pipe on top of a full scale drawing.
Tried to improve method of measurement by printing out a A0 piece of graph paper and using that as the background to lay the pipe on. Better/easier and more accurate again, but still not spot on, have to check and adjust using the pipe on top of a full scale plot.
Short of buying some type of expensive 3D measuring machine, which in our case would not warrant the cost as we do not do this type of drawing 100 per cent of our time, not even 30 per cent, what is the best method of measuring pipes accurately.
I have a piece that I'm trying to develop to add into an assembly. The piece I'm trying to create is a cast piece of steel that I'm trying to form to a radius. The piece basically starts out as a flat part and then is formed to a radius. I want to form it from flat to radius so that the contours will match the radius of the piece.
Is it possible to calculate the deflection a steel block will get, just form it one weight. Just use standard steel material, it is only supported at the end.
I want to create frame made out of structural steel. In order to do that Invwentor is giving me no option but to make Layout Sketch (any other way?), which then i should use for inserting members. Now, when i want to creat layout it does not give me an option of assigning it to a work planes i created. It always sketches it in default XY plane. I need to create 3D layout that will follow several work planes i created. I tried selecting any of the other work planes before clicking on layout button but no luck.
I am looking at the Content Center data. In this specific case, ANSI AISC Rectangular flat bar steel.
The calculations for Section Modulus seem to be the same for both parameters Wx and Wy. The calculation for Wx shows in the column properties as: (({G_W} * {G_H} * {G_W}) / 6) The calculation for Wy shows in the column properties as: (({G_W} * {G_W} * {G_H}) / 6)
These calculations show in the Expression Column as red text. I can modify them but I have no option to OK the dialog box.
The Moment of inertia calculations that are later in the family table use these sections as part of their calculations.
Am I wrong here in my belief that the Section Modulus calculations are wrong and therefore the Moment of Inertia are wrong also?
As an extension of this question, does the Stress Analysis in 2010 use these calculations? Are these numbers used anywhere?
I am trying to constrain a curved wheel to a round, steel track. No constraint has been effective so far. Is there anything I can do to make the wheels stay on track?
When assigning materials to a part in inventor the process is simple, however when one wishes to assign a specific steel type ie ASTM A516 as opposed to just a generic steel then this is where it gets a little more complicated.
This specific steel type will also need to be called up in the parts list relevant to the individual part that it is attached to.
I know that a custom material can be added to the favourites section in the materials library,and this can be done if required.
Have i delved deep enough into the inventor materials library , do the basic steel and others materials ie plastics break down into specific types with their elastic properties,yield stresses etc etc in other words a more comprehensive materials library or is this something that must be created by custom material input.
I am looking for the best way to place multiple columns in a single part file (as independant parts). I want to do this to accurately represent a steel structure that we purchase with a single part number. The structure is purchased and not modified so I figured a single part file would be better than an assembly file with multiple parts.
I thought the best way would be to extrude a 2D wide flange beam profile. However I would like to just pick the profile from a database (content center?) instead of going through the hassle of sketching each profile manually.
