请根据此草图完成线稿。请阅读并参考蓝色文本注释，消除手绘带来的模糊和粗糙感，创建精确的线稿，使其看起来像是 CAD 工具的输出。请调整线条粗细，例如将脊线画粗一些。请删除蓝色文本和线条，不要将其包含在输出图像中。 请以相同的方式完成此草图。
Please finalize this rough sketch and create line art. Read and refer to the blue text annotations, eliminate the ambiguity and roughness associated with handwriting, and create precise line art as if output from a CAD tool. Vary the line thickness, such as making ridge lines thicker. Delete the blue text and lines, and do not include them in the output image. Please finalize this rough sketch in the same manner.
