AutoCad :: Drawing For Laser Cutting Machine
Jun 22, 2011
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 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 am trying to cut paper on my laser engraver from a design on X3. It works but the engraver is cutting out the design. I want it to cut out the background and leave the design intact. I know this can be done and there is probably some very simple thing I am overlooking but I just cannot seem to wrap my brains around it.
For this to work how I want it, I have to change the X3 design to have a "negative" effect, as the engraver recognizes the black so background must be black and the actual design left white.
I tried to convert my design to a bitmap, but then it loses integrity and lines become pixelated. So other than this I am not sure how to get the background black.

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 am trying to use autocad to nest parts for cutting on a cnc machine. is there any way to make a 2d part have a projected boundary of say .5 inches larger than the part so another part cannot nest closer than that. after the nesting is done, the boundary would be removed. the parts are different sizes and shapes so the projected boundary would have to enclose the part.

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.

Using Autocad 2000 LT. Need to create a 2D basic drawing showing 14 TPI external and internal threads with a certain class of fit joined togeather. The basic drawing needs to be drawn in such a way that it could be easily changed to show different Threads Per Inch and or class of fit. Then, with that approach in mind, what would be the basic steps I should take in order to create the basic drawing and then easily change it to show different TPI and or class of fit. Note: I only need to show the external and internal threads, not the entire screw or object attached.

Currently I'm converting one of our machines from AutoCAD to Inventor 2009.
This machine can vary from 1200mm to 1600mm and has a couple of options to choose from for our customers.
These dimension changes are all driven by a single excel file and the options are controlled in the an IAssembly.
Some of the 2D drawings will have a variable width, in our ERP system they are marked width dependable as followed: "partnumber/1200" or "partnumber/1410" in which 1200 or 1410 is the machine width.
Is it possible to have the 2D drawings automatically update the partnumber? so if I configure my machine as a 1200mm machine it automatically changes my drawingnumber to the actual machine width?

Got a new computer. Copied and upgraded Photoshop CS2 to CS5. I would like to give the old computer to a family member or friend. Will they be able to use the CS2 on the old machine? (an iMac 10.6) or is that the end of that CS2?

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 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 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.

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.

I have a DXF file in Autocad LT which I need to import into a CAD Reader for a CNC machine. The cad reader can only view a 2D image of the TOP of the part. The problem is that the view I want the cad reader to see is the RIGHT hand side view in Autocad. Is it possible to reassign the views in Autocad LT 2008 so that the right hand side view become the top view therefore allowing the cad reader to see the correct side.

If I create a drawing in AutoCAD Architecture 2010 on a 64 bit machine is there any way I can still plot using my old 32 bit printers?
I'm thinking print to dwf or PDF then open the file on my old 32 bit machine for printing?

this is the message I get when trying to save, One or more objects in this drawing cannot be saved to the specific format.
The operation was not completed and no file was created. I was able to save at lunch and now its not a happy camper.
