AutoCAD 2010 :: Extracting Geometry For Laser Cutting
Mar 6, 2012
Currently, I am using Inventor to produce inventor DWG drawings for our supplies to read using autocad and trueview etc. One of our suppliers is a laser cutting firm and they need us to produce a seperate DXF file from our inventor drawings (for the flat patterns). As this has to be done manualy and is potentially error prone (as drawings can be automaticallyt updated where as DXF's requre a seperate 'save as' we had hoped to be able to just send the Inventor DWG for them to extract the geometry of the blank using their copy of AutoCad. I noticed that when opening an inventor DWG in autocad, the 'model' contains no geometry and it is placed on a seperate tab called sheet 1 (or whatever the sheet was called in inventor).
Is there any way that this data can be extracted from the DWG so that they may manipulate the geometry?
I have attached an Inventor DWG for reference.

I need to send 2D drawings for laser cutting. Opti is the laser software..My issue is that the laser cuts to each grip and gives the cut metal a serrated looking edge.
Removing/simpliying the lines into fewer (microscopic!) segements or being able to adjusts the number of grips.

I need to cut some flat veneer using a laser machine, like making a jigsaw puzzle. The laser operator needs a drawing in the .dwg format.I will be drawing a 2d shape using a photograph in the background to copy.
I need to make the shape cut up into sections so I can assign a different bitmap to each section, at least for the design part of it. Since I'm more familiar with Max it'd be easier to do the design work there and export the file.
What I need is to make 2 or more closed spline objects that share adjacent lines so that each section has a surface that can accept an individual bitmap.

I need to save from Illustrator in .dwg format, for laser cutting. However the scale shown in Illustrator is not the same scale in the .dwg when they look at it at the laser cutting firm.
btw when I export in .dwg format the setting for scale is set at 1 centimeter = 1 unit. I don't know what they mean by unit however.

Is there a way to cut a solid into two pieces using a non-planar cutting plane? I have been tasked with calculating the volume of concrete damage in a chute block. I have a sketch of the damage on the chute block. I created the chute block as a solid and then drew the damaged area extents using plines. This created non-planar plines. Is there a way to get this to work that will allow me to see the volume of the concrete damage? I need an easy way to do this, there are 50 chute blocks all the same size but with varying degrees of damage

I was wondering if there is a way to cut out geometry using a texture map.
So lets say you have a quad thats uv mapped. you apply a black texture with a white dot in the middle. Is there a way to cut that circle out using a method that just aproximates the shape?
I would be using this for complex stuff. I understand its a crazy question but I figured no harm in asking. The only thing I know to do is to apply the texture and then in the viewport just hand cut. But its a lot of stuff to cut so i'm open to any shortcuts and tips.

I have one user that when trying to print to a color laser jet printer it only comes out in color. I even set the Plot style to monochrome.stb, (which is a network file that others use without issue) have Plot with plot styles checked, and even tried checking the black and white only in the printer properties. This is Autocad 2012.
Is there something I am missing to have the print out come out in black and white? Te print preview shows it in color.
Forgot to mention, if another user opens the drawing, it prints in black and white ok.

How in AutoCAD 2012 to be able to extract more than 256 columns worth of attributes per block?
It keeps giving me an error saying that excel won't allow it... excel has had more columns than 256 since 2007!?!?!
Or is there a third party extraction tool that I can use that extracts information in the same way the AutoCAD one does?

I need to load a couple hundred drawings to Vault. Most, if not all, of these AutoCAD drawings use the 'smart title block' and I was wondering if there was a way to extract all the data from the title blocks into an excel .csv file to then be imported into Vault saving me SOOOO much time and work.

Just recently we upgraded from ACAD 2010 to 2011. Some users are still on XP and some are on Windows 7. Since we began making the jump to ACAD 2011, we have begun to notice more and more drawings popping up with blocks no longer visible that were there the day before. When you go to the block editor, the block definition is still there but all of the geometry has been blown away. The only entity that seems to be immune is an attribute. The only commonality among the various drawings this is happening too is that they are all being accessed from an XP machine. Some folks have had to spend hours restoring all the blocks that were lost and that in itself was a challenge because ACAD already saw the definition so it would continue to blow away the geometry. You could purge the block IF you could find a way to pick it and delete it.

How should I model a random 3D-geometry using AUTOCAD?
I have NEZ data from total station survey of an uneven region. Importing them to AUTOCAD gives me points.
What element should I use to model the 3D geometry enabling me to perform further calculations like volume etc. ?

When I grip-select an image, or pick it at the "select objects" prompt, the image hides all other geometry behind it. Troublesome when trying to fine-tune the image(png background) location relative to other entities.
Image transparency on, draworder back, monochrome, image @ 0'-0"Z.
Image looks fine until I pick it.

Is it possible to have model space geometry print through a watermark in the layout? My watermark consists of mtext with an arial font placed manually in the layout. It is on it's own layer which is set to print at Shade 40 (plot style tables). Draworder works with other layout objects but not the geometry from the model space viewport. My watermark covers the model space geometry so it is not visible when printed. Is this possible?

Screen does not refresh and shows geometry from one of the viewports to the side, as you pan the window.
Geometry stays on when you go to model space.
Was working ok until Autocad suggested upgrading video performance.
Will not work even after downloading lastest video driver from NVIDIA

when I am working on a large drawing and/or pasting as a block, all the grey lines (colour 8) turn to white. When I select a grey line, it flicks back to grey, but de-select, and it's white again.
If I toggle on hardware acceleration, the problem is fixed for a short while, and also if I turn it off, it is fixed for a short while, and also if I save, close and re-open it's good untill I paste a block....
I suspect it may be because of my setup and an un tested graphics card:

I have downloaded an eps file, which I need to cut. I use a graphtec ce5000-60 cutter, and a plugin called cutting master 2 in order to use coreldraw.
when i select application launcher and choose cut / plot, it opens cutting master. when i do this, it only shows the 2 outer lines of the logo i need to cut. I have attached a screenshot so you can see exactly what I mean. I have tried lots of things to recitfy this, but as a complete beginner with this software, I really dont have a clue.

I'm looking to start offering laser cut pendants and such. Laser cutters require AutoCAD files, and I have no idea how to use any of the AutoCAD software (I intend to learn, eventually) but I heard you can take Illustrator files and convert them into the necessary formats. I have experience with Illustrator so I thought that was brilliant.
I took my Photoshop sketch and brought it into Illustrator and traced all the lines on one layer using the Pen tool. It's all straight lines. I temporarily deleted the layer with JPG artwork, then chose the Export option and selected dxf.
I didn't change any of the default options, so AutoCAD version was set at 2000/LT2000, colors set at 256, and raster file format was left at BMP. The "Export Selected Art", "Alter Paths for Appearance", and "Outline Text" options were all left unchecked.
Upon sending the file to my laser guy, he said that when opening it, there were no entities. I don't know what I did wrong. I just exported it as a DWG as well and sent that to him.

I use a NextEngine 3d laser scanner to create organic models. The process is relatively simple assuming you just buy the software that NextEngine supplies (for $995). For this price you get an "auto surfacing" feature and export to STEP or IGES. For me it is hard to rationalize spending that money just for those features, although, auto surfacing makes the process very simple to get a solid into Inventor.
Since I already have Inventor 11 and AutoCad Mechanical 2011, I am hoping there is a way to get the scanned data into Inventor as a solid to edit parts etc, without spending the $995. If I do spend the money, I would like more functionality from the software. I am also looking into Rhino 4 as a possible solution with more functionality for a similar price. I have all the open source programs like meshlab, and blender and they work somewhat.
The Nextengine creates a Point Cloud which can be exported as an .obj or an .STL (which comes in handy for 3d Printing). I use a 3rd party program to import .stl files into inventor. They are imported as a mesh and the "Stitch" command does not work unless you have surfaces (as far as i know). How can I create a surface from a mesh with my existing software?
GOAL: create a surface from mesh data (obj or stl), convert to solid, and edit in Inventor.

I am working on a project where several holes in a sheet metal part will need to be cut as "knockouts". In previous years, either an engineer or the laser cutter programmer would set up the machine to partially cut a circle, but leave a gap to hold the knockout in place (basically a 340 degree arc).
Now that we are using Inventor, is there a way that we can create these features so that they show up in a dwg as a single line? It must be a single line; some of the holes are very small and if the laser makes more than one pass it could affect the integrity of the feature.
The closest I have gotten to accomplishing this is a surface extrusion on the folded part. When I send it to an .idw file, the line appears in the folded model, but I need it to appear in the flat pattern.

I have a back plate made out of 2mm Galvanized Steel. And here is the drawing of this back plate flattened out:
You can see that the cut is 5mm between the back plate and bended out part. This part will be laser cut, instead of being punched out.
Here comes the challenge- No matter what is the distance between bended out part and back plate laser will consider there to be two lines for it to cut *one line on the back plate and one line for bended part. And laser will go there two times even if I will make distance of 0,01mm. Is there any way to make this cut as one line, so laser will make one pass cut?

I have problem printing tiff images with a picture in Windows 7, 64 bit only on a laser printers. The processing of even the simplest of drawings to the printer takes too long, more than half an hour after that or stop with the press or to print only part of the drawing.
This problem does not appear when we print only the tiff images on a laser printer or print the entire drawing to a plotter. Also print these drawings with the tiff images without any problems under the previous operating system (XP). Note that we use the latest drivers for all printers.

I am trying to find a way to import a laser scanned mesh or point cloud file into Inventor (2013) such that I can use it to make a parametric representation of the form. The import format can be STL, OBJ, VRML, XYZ or PLY. I have tried the Mesh Enabler from Autodesk Labs but the files I am looking to work-on are bigger than the enabler can cope with and my system slows right down or locks-up.
I know bespoke reverse engineering software is the ideal way to go but I was hoping there was a way to model over a mesh to represent its form to create a placeholder in a parametric assembly. I'm not looking for accuracy, just a surface or solid output that can be constrained to native inventor parts. If I could get the files to STEP or IGES someway that would be enough.

On an HND assignment there is a drawing of a Villa in plan view with outer walls, inner walls and then some attributed blocks created for furniture. Once drawn the second task is as follows.
Task 2
Write a report describing the methods you used, with a layout plan inserted into the document and to include a bill of materials extracted from the attribute files.
How you would go about extracting the BOM from the attributes?
