I want to move a copy of the right edge of the surface along its top edge for a certain distance (marked with red arrows on the screenshot).distance To do this, I turn on snapping to edges, select the right edge, press Shift + D, move the cursor along the top edge, but there is no possibility to enter the desired distance from the keyboard... In the lower left corner, coordinates in the global system are highlighted and i can enter them, but it doesn't help me. The difficulty is that neither the surface nor the edges are parallel to any coordinate axes. Does anybody has an idea how to do that, or how else this can be done?

  • $\begingroup$ are you edge sliding or snapping another edge to that face? $\endgroup$ – Michael Ben David Apr 19 '19 at 16:15
  • $\begingroup$ @MichaelBenDavid I'm copying the right edge of the face (by pressing "Shift+D") and snapping it to the same face. $\endgroup$ – Антон Антон Apr 19 '19 at 17:01
  • $\begingroup$ better do this press shift+tab to turn on snapping with increment enabled then press ctrl +r and select the area to cut ( in the middle in this case) and click and then slide until the side that you want to. $\endgroup$ – Michael Ben David Apr 19 '19 at 17:07
  • $\begingroup$ I can move the copy of right edge along the top edge simply with snapping to edges enabled. The main question is how can i make the distance, marked with red arrows on my screenshot, equal exactly 0.02, for example. I want to enter that distance from keybord some how. I guess, first of all i need to align the whole face along axes (by pressing S,0,X, for example) than i'll be able to move the edge to the exact distance the way i want, but how to bring the face back to it's first position togehter with the new edge i created?... $\endgroup$ – Антон Антон Apr 19 '19 at 17:57
  • $\begingroup$ g + x + 0.950 for example, but center the edge first to align it like this, also you can the enable the length in right panel in edit mode for seeing how much has of distance on every edge,as i said is more easier to create a loop cut and then edge slide pressing g twice, with snapping enabled with increment $\endgroup$ – Michael Ben David Apr 19 '19 at 21:16

ShiftD duplicating an edge will not cut an edge into the face. The duplicated edge will just hover there, unconnected to the rest of the object. Probably what you want is?...

  • Select the edge you want to slide along, and CtrlAltSpace create a Custom Orientation from it. (Check 'Use After Creation').
  • Create the edge you want to slide, in the face, any old how, eg. K cut it with the Knife tool, not worrying about accuracy
  • GG slide it down all the way to the end of the face, where it will be stopped by the end vertices
  • GYYYour Number move the edge back again, to the required distance from the end, parallel to the orientation edge.

.. but this method will work just as well with a duplicated edge, if that's what you want.

ok as i already told youu in comments just create one or two edge loop cuts (if you need the same edge in the other border add two) in the middle of the faces with Ctrl+R previously before doing this, align the view to 3 or 1 of the numpad keys and then enable snapping with increment and scroll in a little until you see the grid gets smaller enough and then slide that edge loop, until you see a good "distance" or space bewtween the edge and border edge, check the left panel to see how much did you move it, and repeat the same to the other edge

    $\begingroup$ I understood the way, you described in comments, but trying to "catch" the needed distance moving the mouse is less precise way then enter this distance through keyboard. But i didn't know that there is possibility to see distances while moving elements, so, thank you too! $\endgroup$ – Антон Антон Apr 25 '19 at 23:07
