Sketch turning BLACK when Padded

Postby R-INYURU » Sun May 19, 2019 12:25 pm

I was designing a board in Part design, in the middle of it I sketched something(as you can see in the image).

When I tried to Pad the sketch its turning black and it can't be changed.

I have tried to fix it by changing the color back and it doesn't work.
I also tried to open it in FreeCAD 0.17 and still it doesn't work.

OS: Debian GNU/Linux 9.9 (stretch)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.13541 (Git) AppImage
Build type: None
Branch: releases/FreeCAD-0-17
Hash: 9948ee4f1570df9216862a79705afb367b2c6ffb
Python version: 2.7.6
Qt version: 4.8.6
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/UnitedStates (en_US)


This is the version I initially was using.

OS: Debian GNU/Linux 9 (stretch)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.16110 (Git) AppImage
Build type: Release
Branch: (HEAD detached at 0.18.1)
Hash: f7dccfaa909e5b9da26bf50c4a22ccca9bb10c40
Python version: 3.6.7
Qt version: 5.6.2
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/UnitedStates (en_US)

What could be the cause of this issue?
Trying to learn more about FreeCAD, any idea I will appreciate.

Hi
It's because you have traits that cross (self intersection thanks Openbrein) , you have to open all the closed rectangles

What meme2704 pointed out is called self intersection. ;)
This can't be padded, pocketed, ... because it makes the geometric kernel to be lost about what are the internal and external faces. ;)
All your sketches shall be simple closed shapes.

Hello R-INYURU, I'll also just toss this in. Save all your fillet/chamfer features till the end of your model. It will save you some troubles on down the road.

This just happened to me. I had a sketch with a number of holes where I had drawn circles on the holes, which were mapped from a plate with the holes. I couldn't find a way to see if I had overlapping circles, so I started deleting the circles one at a time. Finally I deleted a circle and there was still a circle there, so I knew I had found the one. If anyone knows a way to more elegantly solve this problem, please let me know. Thanks.

If you could attach the file that gives problem someone will take a look. It is too vague now.
