CAD空心怎么变实心？在CAD软件中，要把空洞对象变成实体通常需要进行填充或实体化操作。
操作方法：
1.填充命令：可以在CAD工具栏、修改菜单或命令行中找到填充命令，选择要填充的空洞对象，然后选择填充样式和属性以确认命令。
2.区域命令：用于将封闭的空洞区域转换为实体，在相应的命令下选择要转换的空洞区域即可。
3.外部命令或插件:专门针对将空洞对象变成实体，在CAD软件的扩展功能或插件库中可以找到相关工具。
4.如果没有直接的填充或区域指令功能：也可以手动绘制闭合边界线（多段线或闭合形状）并代替使用它们，先画出闭合多段线或形状，然后利用固体填充工具将其变成实体化。
英文介绍：
“In CAD software, converting a hollow object into a solid object usually requires filling or solidifying operations. Here are some common methods: Fill command: The fill command can be used to fill the hollow area with a solid color.
The specific steps may vary depending on the CAD software, but you can typically find the fill command in the drawing toolbar, modify menu, or command line. Select the hollow object to be filled, then choose the fill style and properties, and finally confirm the command.
Region command: Some CAD software provides a region command that converts closed hollow regions into solids. You can select the hollow region to be converted and use the corresponding command to convert it into a solid entity.
External commands or plugins: Some CAD software may offer specific external commands or plugins specifically designed for converting hollow objects into solids.
You can look for relevant tools in the CAD software’s extension features or plugin library.
Drawing boundaries: If your CAD software does not have direct fill or region commands, you can manually draw a closed boundary line as a substitute for the hollow part. First draw a closed polyline or shape, then use an entity filling tool to fill it with solids.”
