DXF files to SendCutSend

I’m trying to export a 2D drawing as a DXF so I can upload it to SendCutSend.com

With the drawing created I go to export it as a DXF to my Files app on my IPad.

It shows up there and I’m able to import that same file to Shapr3D perfectly fine.

When I go to SendCutSend.com I attempt to upload the DXF file to their instant quote system. I can see the DXF file but it will not let me select it for upload.

Where am I going wrong here?

Ok. I’ve used them and also OSHCut.com. The issue I’ve had is that all DXF files must be from the Top View. You’ll need to rotate any side views to the Top view, then export all views from there. Try that, and let us know. McD

Also, if I recall, they don’t support the upload off the iPad. You’ll need to go to a computer. :point_left:

My Process To Export DXF (or other formats) for Laser Cutting, CNC, Waterjet, etc.

Note: the export will be in two dimensions in this example as items are to be cut, not 3D machined. These steps were developed for the iPad version of Shapr3d, but should be similar on the other platforms.

Preparation & Overall Guidance

  1. Create a free account at viewer.autodesk.com, as well as at your machine shop of choice (sendcutsend.com, xometry.com, etc.).

  2. Start with a small object or small set of objects until you are comfortable with the process.

  3. sendcutsend and some of the other services operate so quickly that you may not have an opportunity to cancel the order if you have made an error, e.g. if you sent a file with your object specified as 20 x 15 millimeters rather than the 20 x 15 inches you intended.

Steps to Export Your Design

  1. Open the design in Shapr3D. Make sure your sketches are accurate - we will be exporting the sketches, not the objects. If necessary, hide the objects. (In this process as I describe it the objects will not be exported, so hiding is only to help you validate the sketches.)

  2. The cutting equipment will be working from the top, so rotate your sketches, if needed, so that the top view shows the outline of your parts.

  3. Tap the export button in the upper left - the Export window opens.

  4. By default the “Usage” tab is selected under the window heading. Tap “Format” instead. Tap the file type (DXF in my case).

  5. The “Export DXF” window opens. This is almost the same as the the “Export DXF” window that will open if you use the “Usage” tab and select “DXF for a Drawing”, but they are NOT the same and the functionality is different.

  6. Do not change the file name (displayed below the window header, typically “Drawing”) at this time.

  7. By default the “Drawing” tab is selected below the default file name. Tap the “Sketches” tab instead. Notice how the options change.

  8. Change the file name now. If you had changed it earlier then it will revert back to Drawing after you tap the “Sketches” tab.

  9. Change the defaults if you need to, but do NOT change from TEXT to BINARY under the Advanced Options (it is the only Advanced Option at this time) as this will create a .dxb file instead of a .dxf. Some applications cannot read .dxb.

  10. Tap “Continue” at the window’s bottom - this opens the “Save This File” window. Tap “Save to Files”, choose the appropriate folder and tap “Save” in the upper right. The “Save This File” window remains open which may give the impression that the file has not been saved. Look in the folder you selected to confirm that the new file is there. I typically save to my iCloud Drive so that I can open files exported from my the iPad on my computer.

Validate the File

I typically do this on the computer, not the iPad, as sendcutsend sometimes has problems recognizing files on the iPad.

  1. Go to viewer.autodesk.com and login. Drag-and-drop or browse to open your file via the blue “Upload new file” button in the upper right.

  2. Make sure the sketches look correct.

  3. Click the “Measure” button in the row at the bottom of the screen then make sure the “Distance” button, which will pop up in a new row above the row containing “Measure”, is active.

  4. Click the starting point of a line of your choosing, then drag (not click-drag) to the end of that line, click again and confirm that the measurement is as you expect. You can close viewer.autodesk.com now.

  5. Login to sendcutsend.com (or your selected service) and upload your file. Use their tools to validate that your objects are sized correctly and in the correct unit of measure (inches or millimeters). Sendcutsend will open a “Verify Units” window that shows the total length, total height (width?) and the units of measure of all objects in the .dxf file.

  6. Walk thru the steps to complete your order.

That’s It ! Good luck.

I don’t understand the need for viewer.autodesk. I do get the reason to use the PC for both SendCutSend and OSHCut, as they have not developed the iPad interface. I simply save my files to iCloud, access them via my PC, then export them to either laser cutter. I do my designs in inches, and haven’t ever had an issue at either fabricator with units. McD

Thanks for your feedback. The viewer.autodesk steps are optional. I found it helpful the first time to validate the length of edges. Sendcutsend only provided the total width and length of the metal plate/sheet, and with 14 distinct objects in the drawing (to be cut from one sheet), I wanted to fully insure my $ would not be misspent if some sizing was off.
