Problem performing boolean between additive loft and pad

Postby falviani » Sun Nov 01, 2020 7:02 pm

Hello All,

Here is my setup:
OS: Windows 10 (10.0)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.22865 (Git)
Build type: Release
Branch: master
Hash: 3c307b7a3c222d66cb70695cdcf79606553fcb91
Python version: 3.6.8
Qt version: 5.12.1
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/United States (en_US)

I have a model where I need to perform a boolean between an additive loft and a pad, to remove part of the loft (as shown):

My problem is that I can only select 1 node in the tree at a time, so I can't perform the operation (file is attached). Could anybody explain what's going on so I can correct the problem?

Thanks in advance,
Frank Alviani

In Part Design the last feature in the tree (in this case Pad) is the cumulative result of all previous operations.

Thus what you see IS the current state of the solid. I.e. the loft is part of the Pad. So, you can't select the loft to remove from itself, so to speak.

In addition Sketch008 and 009 are not attached to anything. (though nothing to do with the your problem.)

Shouldn't the last Pad be a Pocket instead?
