I am fairly new in Blender coming from SketchUp.

After some hours 12 working with Blender i'vv tried different ways to precise model this "simple" shape into a single object. I seems like its better to not use the extrude manifold option. Some modeling guiding is very much appreciated :-)

3d

2D

dimensions

make a cut on 2.2mm

make 2.2 mm height

Create a cube, stretch it on X, rotate it 45° on X, cut it in half and mirror with a Mirror modifier:

Select its end and in front view, use the Shear tool (AltCtrlShiftS) and in the Operator box choose Offset > 1:

Cut an horizontal edge with the knife tool K to activate, A to cut orthogonally, C to cut through, press Shift if it is supposed to be cut at its middle:

enter image description here

Extrude the bottom triangle on X:

enter image description here

To measure an edge, you can enable the MeasureIt addon. Select an edge then in the N panel > View > MeasureIt Tool, click on Show and clik on Segment. You can remove the display with the X buttons a bit below on the same panel:

  • $\begingroup$ Thanks, I can do it this way. Will try to be precise, the height of the little extruded triangle needs to be exactly 2.2mm perpendicular on the bottom edge. $\endgroup$

  • $\begingroup$ there are some measure tools in Blender, you can activate the addon MeasureIt for example, not sure where these 2.2mm are supposed to be though, could you please add a picture in your original post? $\endgroup$

  • $\begingroup$ Hi @moonboots I will add the measure it addon and give it a try, also added some dimensions. Precise modeling is a bit difficult but can give it a try to move the 3D mouse and try to snap the knife tool to it if that is possible. thanks! $\endgroup$

  • $\begingroup$ Blender is not made for industrial modelling but they are some tools that allow measurement like MeasureIt or Edit Mesh Tools, also Archimesh or Archipack addons $\endgroup$
