This should go to Help subforum. You can start by reading the IMPORTANT link ot top there and providing some more info: your FreeCAD version, screenshot of the problem, file with the problem, ... By your explanation I at least have not experienced such problem. There is a clipping plane problem some...

In screw_maker.py at line 113 we have standard diameters: standard_diameters = { 'ISO4017': ('M1.6', 'M64'), # ISO 4017 Hex-head-screw 'ISO4014': ('M1.6', 'M64'), # ISO 4014 Hex-head-bolt 'EN1662': ('M5', 'M16'), # EN 1662 Hexagon bolts with flange, small series 'EN1665': ('M5', 'M20'), # EN 1665 He...

Sorry, I was too quick :) I can confirm that behavior. Also the removal of horizontal constraint OR sketch becomes fully constrained. I tried with OS: Windows 8.1 Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.17.13541 (Git) Build type: Release Branch: releases/FreeCAD-0-17 Hash: 99...

With the speed things are progressing you should really include full version info with such posts... Also a screenshot in the buggy state would help. I tried an here sketch shows as underconstrained with 2 DOF. . Bug_sketcher_2dof.JPG . OS: Windows 8.1 Word size of OS: 64-bit Word size of FreeCAD: 6...

If you are going to make something that is symmetric along an axis/plane design it that way. Draw the sketches so they are symmetric along X/Y axis.

First, avoid mapping sketches to faces (where you select a face and then create a sketch on it). Search the forum for "topological naming issue". Second did you create Pad001 just to have a face where to map Sketch002? And later you removed that whle padding with a pocket? Juct map the sketches to b...

When I have multiple features that depend on a single master sketch, I make a copy of the CarbonCopy rather than a new CarbonCopy for each feature. Perhaps that is not the best way or a bad habit? That is actually quite clever. If you have one full CarbonCopy it is easy to find it in the tree and d...

Sketch has its own coordinate system which depends on its Placement property. If sketch is under a body them Placement also depends of its Attachment mode/properties. When referring to Base planes we usually mean bodies base planes (if part design is used). Those under bodies Origin property. The "t...
