Can anyone help me with the steps required to make a 3d extrusion of a pillar with compund angles? So far I have only found one video on youtube that touches on this subject, however, the spoken English is not very clear to me. It uses taper angle and a direction, for the extrusion. https://www.youtube.com/watch?v=t5LDmCXYF8E My pillar must rise at 45 degree and the 45 degree taper inward at 30 degree. The pillar is 30 x 30 mm height is irrelevant. The pillars are used to hold a roof construction of a hexagon shape. Where the slope/pitch of the roof is 45 degree.  |

Hello Parken26, I don't know if the faces are twisted and "extrudable" or not with AutoCAD without facets. But I have placed in the CAD/BIM Blocks library here in the site the AutoCAD file : 301-PJH.dwg I have placed some additional dimensions, could it be OK for you ?

Set a UCS on each of two vertical faces, and drawing Lines at the right angles is simple enough [red]: Mirror those over to the other side:  and a couple of SLICE operations using the 3points option and Osnapping to ENDpoints of those Lines, keeping the lower portion each time, takes care of it:   |

A question never comes alone... I am struggeling with making the roof plates, I have already cut these, and made sure the calculated miter and tilt angles are correct, but I would like very much to finish my drawing, then I wil lbe able to quickly scale this house to a smaller or larger version. How do I get the roof plates to align with the 45 degree angle? Please note that the annotated width and height of the triangle may not be accurate to the drawing.   |

Move each plate into position then rotate to match the roof angle. ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |
