Question: How can I ensure that the “pick point” (or “select object”) is closed when filling in CAD? A problem that has been bothering me for a long time! Could someone give me some advice? :(
The shapes you draw must be closed, and there should be no overlapping lines
It’s best to use PL lines when drawing, and close the shape with a ‘c’ to ensure it forms a closed shape; this makes filling it easier. When filling, don’t make the area too large – keep the entire filled region within the window, and select that area for filling
Extended functions can be used to ensure a closed shape is obtained
Commands such as extend and cut can be used to eliminate gaps, and after filling them in, it becomes closed
Following the previous reply: my own experience. At points where picking up is not possible, it is possible to zoom in or out to a certain extent before attempting to pick up the item; usually, zooming in is used. Of course, if this method doesn’t work, there’s no choice but to redraw it. Note: What was said above makes perfect sense; I’ve also learned from it here.
I usually draw the diagram first; if I can’t fill it in directly, I zoom in to check whether there are any obvious unclosed areas. If that doesn’t work, I use PL lines to trace them out. Since many line styles are on different layers, such problems are inevitable. I just trace them with PL lines, create a separate layer for them, and then hide that layer
For more complex regions, it is recommended to divide them into several simpler faces, fill each one separately, and then delete the dividing lines. It is best to use PL to draw these dividing lines, and they should be closed at the end.
When drawing, turn on object snapping, especially endpoint snapping; this will ensure that the shapes drawn are closed. As long as the shapes are closed, it’s fine to select “Pick Points” when filling them in.
