PROE5.0中 3D图转2D,怎样设置,比例?

2d图的单位设置是英寸，将drawing_units 默认是 inth 改成 mm

顺便将我用的模板文件给你一份，在config文件中加入
drawing_setup_file $PRO_DIRECTORY\text\gb.dtlformat_setup_file $PRO_DIRECTORY\text\gb.dtl
将下面的存成gb.dtl放在上面的目录中，也可以自己改

如果你是想保持原始尺寸不变的话，可以选择实际尺寸模式，并确保在转换前先锁定所有大小和位置信息。这样导出的2D图就是与3D模型一模一样的大小了。记得检查一下单位是否一致

要设置比例的话，在工具->选项->图纸输出里面找找看。那里有默认的比例尺供你选择，比如1:1, 1:20等。如果你需要自定义比例，可以手动输入并保存为模板

在PROE0中，转2D图时，首先打开你的3D模型，点击视图菜单，选择投影，然后在下拉列表里选一个适合的视图方式（如俯视、侧视等），接着调整比例。你可以在显示选项卡找到比例设置，输入你需要的数值或者使用预设的比例
