Sometimes the line cannot be connected to the device when drawing it
Thread Content
When drawing a line, it seems like it’s being pulled toward the device, but the line drawn doesn’t connect to the device
Did you make the image too large?
It must have been zoomed in too much, and capturing wasn’t enabled as a result. It has already been drawn; use the extend command. Turn capture on later.
I’ve encountered this problem: a straight line passes through the diameter of a circle. Using the cut command, I remove the part of the line that is inside the circle; upon closer inspection, it seems like there is no intersection between the line and the circle, but object snap allows me to locate the intersection point... I don’t understand it...
I usually prefer to draw a bit over the line first and then use the interrupt command
Use extension or cutting; it’s better not to connect directly. The process diagrams are fine, but the equipment diagrams can sometimes be incorrect
That’s because you set it too large; in fact, they intersect. You can use the “Regenerate” command. Last edited by wisdom1010 on 2009-4-2 at 12:58.]
Turn on object snap, or use the extend command for the lines that have already been drawn
It’s best to use the extend command: by drawing a short straight line, it’s possible to extend it to the device, which saves time. Of course, the capture command is also very useful, as it’s effective for capturing key points.
I’ve always found the commands related to extension to be a bit difficult to grasp.
It’s easy to understand. Do you know how a circle is made? A circle is, in theory, a continuous curved line with the same radius of curvature at every point. But it’s very difficult to do in terms of time. Therefore, mathematically, a circle can be regarded as a regular N-sided polygon; as N approaches infinity, the length of each side approaches zero, and thus it becomes a circle. Understanding this point helps explain why circles in CAD sometimes don’t appear circular. So in your case, the line intersects the circle, but when it is enlarged, those intersections are not visible; this is normal. It can be seen using the redraw or regenerate command. Moreover, this kind of enlarged view of the drawings has no practical value; when you create the drawings, you will find that straight lines and circles intersect, and circles do not become non-circular.
Draw the line straight through and then break it. or extend
Visual error! Using object snap will solve the problem.
Some CAD software also has issues; its precision isn’t very high. A certain domestic CAD program I used in the past often had such problems.
If it has already been started, as someone mentioned above, you just need to go to the editing menu and select regenerate
Don’t trust your eyes too much; don’t think it looks connected just because you see it that way. Use more tools to capture it directly, either with extension commands or by stretching it first and then using the cut command. Overall, it’s best to be able to capture everything in one step.
