Re: Lifting the restriction on bodies only allowing one single continuous solid

The restriction has been removed there for over 12 months without complaint of programmatic problems that I am aware of. Do you know how well it is tested? How many people used it? Just one sample point but I guess I'll add that I've been using it for close to two years and never had any problems i...

Re: Approximate a Point Cloud with a surface

This is great! Thanks for going through the trouble. A tutorial showing this off was very needed. I'll have to look at getting a better fit of the BSpline surface to the point cloud, I noticed the version you made still is off by a small amount on some of the edges (see attached). I wonder if making...

Re: Curves workbench

I want to use FreeCAD to fit a surface to a point cloud generated from STL. The reverse engineering WB does not generate results that fit the point set well. With the help of the Surface wb you have another option to create surfaces on a mesh. There you will find a function Curve on mesh that allow...

Re: Curves workbench

I am making a tutorial based on your mesh. Here is a quick result (may not be optimal) Well then, you might be interested to know where the mesh comes from. I am working on making a valid CAD model of a Nintendo GameCube controller. I've wanted to do this for a while but never had good data to base...

Re: Curves workbench

Hi, First, you cannot use tools from Curves WB, since they only work on grids of points (points sorted in rows and columns). However I get a rather simple BSpline surface that seems to fit your points pretty well with the Reverse Engineering WB : rev-eng-point-cloud.jpg You can tweak the settings f...

Re: Curves workbench

Hi, I am trying to reverse engineer some surfaces from scanned data. I use Blender to extract specific faces from the full scan. I want to use FreeCAD to fit a surface to a point cloud generated from STL. The reverse engineering WB does not generate results that fit the point set well. What would be...

Re: [SOLVED] Python 3D Image/Picture Capture Object Clipping

I figured out the problem. If taking the images to soon after changing the camera or moving a part then the objects will end up looking like this.

In my case, I was able to use QTimer from Qt at a delay of 250ms to get clear images.

I'll leave this post up as it may help someone in the future.

[SOLVED] Python 3D Image/Picture Capture Object Clipping

Hello, I am using Python to collect pictures of objects as they are being assembled. However, the objects in the images tend to get clipped out of view. The first image below shows the clipping. What options do I have to fix this clipping? Is there some way to automatically adjust the far and near d...

Auto snap in sketcher.

As far as I'm aware, there isn't a way for lines or anything to find an intersection between lines and make a point there to snap to. If you have used any other parametric modeling software, then you should know that most of them will find the point where two lines intersect, midpoints, and straight...
