Re: Why does FEM meshing doesn't generate volume elements in some cases

To get reliable meshing results, you should provide model data following an improved quality standard. What you mean by provide model data? You mean I must set some value or data something in Freecad? Or should I send new file? Or should I provide better picture like you in example u provided? An I...

PAN (ctrl + right click ) , popup context menu, how to fix?

When I drag in FreeCAD I often use ctrl + right mouse click, normally I can release right mouse click only hold ctrl key (also shift in rotate view) then release when I go to view I want. Reason I don't like middle mouse click/hold coz button is hard. Also middle+right click is hard to press and rea...

Re: Why does FEM meshing doesn't generate volume elements in some cases

I see. Here is the file. I design cnc and would like to see deformation of structure to know estimate how strong or weak point of each of design. I hide other part only left "a001" for FEM. It is base for x-axis. I've try create mesh from whole body, all of them created no volume. So I try on x-axis...

Re: How to create face from shape?

Thank a lot! For the info. Also after a lot use freecad to design cnc these pass week I learn a lot more. I often use sketcher with pad to model 3D. Only draft to do the simple draw like line rectangle only. I faster and flexible to me. One thing I found it useless is measure distance in draft WB. W...

Re: How to create face from shape?

Wow thank you! You explain me txt and pic and animation make me clear! Also I learn more about draft and sketcher Draft can only create a face from a single closed profile. In your DXF, there are 10 closed profiles: It seem to me sketcher is more advance than draft. Since in your example rectangle a...

Re: How to create face from shape?

I select all sketches or few sketches in treeview and sketch>merge sketch also nothing happen. Just same result like upgrade. Don't know why, it should combine all shapes/sketches into one shapes/sketches is it not?

Re: How to create shape from shape?

Here is link that I get the file also I've attach it. https://grabcad.com/library/60x60-8n-br-aluminium-profile-1 EDIT: forgot about the 4 "cross shape" holes inside and the 4 little rounded squares. You need to create 10 different faces. I understand hole for 4 cross shape, 4 little rounded squares...
