如何在 OpenSCAD 中使用 Sphere 渲染 dxf 文件 [英] How can I render a dxf file with Sphere in OpenSCAD

问题描述

我在导入 dxf 文件时遇到渲染问题.

渲染成功:

• 对 dxf 文件使用 linear_extrude() 并显示一个球体.
• 仅对 dxf 文件使用rotate_extrude().

渲染失败:

• 对 dxf 文件使用 rotate_extrude() 并显示一个球体.

这是我的源代码:

module loadFile() {旋转挤压()import("import_exercise.dxf");}模块 loadSphere() {翻译([0,0,-30])球体(10)；}加载文件()；负载球()；

错误信息如下:

错误:CGAL_Nef_polyhedron3() 中的 CGAL 错误:CGAL 错误:断言冲突！表达式:e->incident_sface() != SFace_const_handle() 文件:/Users/kintel/code/OpenSCAD/openscad/../libraries/install/include/CGAL/Nef_S2/SM_const_decorator.h 行:329

I have a rendering problem about importing dxf file.

Rendering success:

• Use linear_extrude() for a dxf file and display a sphere.
• Only use rotate_extrude() for a dxf file.

Rendering fail:

• Use rotate_extrude() for a dxf file and display a sphere.

Here is my source code:

module loadFile() {
    rotate_extrude()
        import("import_exercise.dxf");
}

module loadSphere() {
    translate([0,0,-30])
        sphere(10);
}

loadFile();
loadSphere();

Here is the error message:

ERROR: CGAL error in CGAL_Nef_polyhedron3(): CGAL ERROR: assertion violation! Expr: e->incident_sface() != SFace_const_handle() File: /Users/kintel/code/OpenSCAD/openscad/../libraries/install/include/CGAL/Nef_S2/SM_const_decorator.h Line: 329

Thank you!

解决方案

The problem is in the dxf-file. Your model touches the y-axis in 1 point. Explanation see in openscad forum. I modified your dxf in two ways. In the first the y-axis is not touched by a point but by a shape, in the second the shape is 0.1 mm parallel to y-axis. Both render without error and the resulting design is valid!

You can download the dxf-files from box
