If yes, then this should be simple :

but what I miss is the OCC 7.3 part... in which way can I install occ7.3 for a building? And can those coexist with occ.7.2?
thanks for your support

Here are my notes for building OCCT 7.3 :

Code: Select all

##########################################################
# OpenCascade 7.3.0 build instructions for Kubuntu 18.04 #
##########################################################

# install needed dependencies

sudo apt install cmake build-essential libfreetype6-dev tcl-dev tk-dev libxi-dev libxmu-dev libglu1-mesa-dev mesa-common-dev 

# fix for the "xlocale" bug

sudo ln -s /usr/include/locale.h /usr/include/xlocale.h

# build and install

cd ~/Software/opencascade-7.3.0
mkdir ./build
cd ./build
cmake -INSTALL_DIR=/usr/local/occt-7.3.0 ..
make -j8
# the install step below shouldn't be necessary for building FC
# sudo make install

Thanks a lot!
I'm going to do the building

Can you compile FreeCAD master ?

Hi @Chris_G
I have built correctly OCC 7.3.0

Would you please have a look at?

Thx again

[Chris_G]

it seems that Cmake doesn't find OCC.
Contrary to what is written in my previous notes, it seems that I did install OCC in /home/tomate/Software/opencascade-7.3.0_install, and I have set these cmake variables for FreeCAD build :

Code: Select all

OCC_INCLUDE_DIR			/home/tomate/Software/opencascade-7.3.0_install/include/opencascade
OCC_LIBRARY			/home/tomate/Software/opencascade-7.3.0_install/lib/libTKernel.so
OpenCASCADE_DIR			/home/tomate/Software/opencascade-7.3.0/build

[easyw-fc]

it seems that Cmake doesn't find OCC.
Contrary to what is written in my previous notes, it seems that I did install OCC

thx! finally I got it built!
Just a great addition and as easy as just selecting the faces to be defeatured!
Fillet and Chamfer easy to go away too
Looking forward to see it in the main branch

.. ping

PS @sgrogan do you think it would be possible to have a Windows daily build with OCC 7.3?
PPS my defeaturing tools will be still useful for stable and legacy FC builds

[efyx]

This looks really cool, maybe it could be enter to direct modeling and could contain also standard holes/cutouts. See example https://youtu.be/Idu7P5C1QIs?t=8m15s (I reccomend to see all, because IronCAD have very good direct modeling).

[Chris_G]

Oh no, it looks like Mr. Silly made a mistake with "git rebase" ...
Now, my commits are duplicated : https://github.com/tomate44/FreeCAD/com ... featuring3
I don't dare to try any "rescue" on the repo, because I know I am able to destroy it MUCH more
Help, please ?

Code: Select all

git checkout -b defeaturing4 defeaturing3
git reset --hard 5129f8fccc

If this isn't what you want:

Code: Select all

git checkout defeaturing3
git branch -d defeaturing4

Now you will be right where you started

Thanks tanderson,
The git reset failed.
But I "think" I managed to fix the problem with the branch-copy trick.
