[SOLVED] How to make a hole in a tapered, extruded object?
I'm very new to FreeCAD, so this may be a silly question.
I can create a 3D object in Part Design workbench using Pad and then put a hole in it via the "Create a hole..." icon.
However, I want to make a tapered object, which I can do with Extrude in the Part workbench, but then I can't see any way of adding a hole.
If I use Sketcher to draw a circle, then return to Part Design to access the "hole" icon, I typically end up with a message, something like:-
Cannot use selected object. Selected object must belong to the active body
Can someone point to a tutorial that may help me? If not, maybe outline the main steps/workbenches/tools?

Re: How to make a hole in a tapered, extruded object?
hi and welcome to the forum.
the recommendation for new users is to avoid mixing part design wb and part wb, it is possible to to use them together,
but one first has to learn how and under what circumstances it is possible to use them together.
if you follow this tutorial document you will learn how to make a hole with part wb.
btw, tapered can mean a lot of things, there is also PartDesign_Draft

Here is an example made purely in Part Design WB.
This uses both additive and subtractive lofts.

Re: How to make a hole in a tapered, extruded object?
for me "tapered" means to make a nut
make an object with PartDesign or PartWb
make a "tap" with the Fastener workshop
Boolean subtraction, unfortunately only PartWb allows it in this configuration

PartDesign wb with PartDesign_Boolean
You should try 0.20 : https://github.com/FreeCAD/FreeCAD-Bund ... kly-builds (Holes with thread)

Re: How to make a hole in a tapered, extruded object?
Sorry, unrelated in English. You may mean "tapped", which is not the same as "tapered".

Re: How to make a hole in a tapered, extruded object?
The error means the sketch needs to be inside the body in order to use it part design. You can drag and drop it into the body. The body also needs to be active, which can be done via right click context menu.
If you want to stay in Part workbench you can extrude the hole, and then use the boolean cut operation to cut the hole from the other part.

Re: How to make a hole in a tapered, extruded object?
how do you say "a conical threaded tap" in Yenkee'sSorry, unrelated in English. You may mean "tapped", which is not the same as "tapered".
""tapered tapped tap "" it's a lot of tapettes (sorry french's jock)
seriously, what do you call the cone nut in picture

Re: How to make a hole in a tapered, extruded object?
Many thanks to all for making me feel so welcome on my first post.
Sorry to have confused you with the "taper/tapered/tapped/tap/tapettes" trap.
Yes, taper has several meanings even outside the world of FreeCAD; decreasing width or diameter of an object, wax coated wick used to light candles, ugly looking animal that lives in sou...Oh wait, that's a Tapir.
I've read everything in this thread including heda's excellent tutorial. Great stuff!
Seems to me that the simplest method is probably to run a Boolean Operation with a cylinder
I'm off now to add a counter-bore to this object, so there's no doubt that "I'll be back!"
Many thanks once again.
