Re: My Project: Quad Headlights - Product Design.

Click the sketch, Edit>Copy (or duplicate). (I don't keep the ref's when prompted) Paste the sketch into another Body. Then, open the Sketch workbench and use the sketch mirror tool to flip it. If tool not present, learn how to add the tool/icon to the toolbar. FYI - I do things my way: I think of a...

Re: Help Exporting STL file from Step Import

First, verify all is good by doing a simple test.
Attached are the three individual part step files and the assembly step - go thru the process I laid out and see what happens...
Then, Also attached is the Freecad file without the boolean op

Re: My Project: Quad Headlights - Product Design.

There are many ways to accomplish a Modeling goal. I prefer using PartDesign workbench 95% of the time. To the show-n-tell of my post: I created the footprint and extruded a solid. Then, drafted the sides, cut the top off part of it to get the lower elevation section, added radius’… Then, made a qui...

Re: Help Exporting STL file from Step Import

Having come to FreeCAD from SolidWorks, ProEngineer, Inventor... other, using PartDesign with it's arrangement of sketches and Pad/Cut/Etc, similarity between those other programs is maintained for sensible design process - if you know one, you basically know the others including FreeCAD/PartDesign....

Re: Help Exporting STL file from Step Import

Having come to FreeCAD from SolidWorks, I've done this a bazillion times. Here's the scoop: An Assembly was exported from SW as a Step file. So, import all the files into FreeCAD. Open FreeCAD, Open the PartDesign Workbench and Create a new File and a Part. (the Yellow icon) Also create a Body insid...

Re: My Project: Quad Headlights - Product Design.

I suspect by end of day, you'll have 10 different approaches...

This one is a simple, quick example only. No intention of doing it like I would do it if it were my project but, you'll get the point.

Mirroring it was done in Part wb (as "bejent" indicated)...

Re: Dare I? OK, An HI issue again .obj as default Export

It would be great to have configurable placeholders... That's easily done - I just did it with a Macro created by 'Recording the steps' Record Macro, Select the Body/Part/Whatever, File>Export, Select output file type, Enter a filename for output file, Select the directory, Apply Stop Recording. Pl...

Re: Dare I? OK, An HI issue again .obj as default Export

For me, Exporting for 3D Printing happens magically, perhaps because I use a Mac. The export panel opens with the filetype of (whatever) the last file type I exported. Screenshot1. I always Export STL. So, it opens with stl as the filetype. If I export an OBJ, then next time, it auto selects OBJ. Ca...

Re: How to do a thread and threading on the same piece

Threads - Two Approaches: #1 - Make thread shape (External or Internal) and Loft it using Helix as Path #2 - Use something like the Fastener Workbench. Use a Bolt/Screw for External Threads and Cut the Head off and add what you need. Could also Bury the Head in a Padded feature. Can add a Pad for e...

Re: Loft face of involute gear works, loft 2d offset of same face doesn't

Yes, I noticed.

My point was/is to enable stacking gears to get one completed gear.
