Or, select the Polyline, and in the Properties box, 'Geometry' category, pick in the 'Vertex' window and you'll see the same kind of X marker at the beginning vertex. If they look closed, but are not actually closed [i. But that leaves them with an extraneous vertex, and a zero-length segment, compared to one that was drawn correctly closed. If that matters, I did a routine here not long ago to close such Polylines "properly" without the extra coincident vertex.
See attachment -- it does it to all Polylines in a drawing, but if you don't want that, see the comment line in the file for how to let the User select the one s they want to close. If it's not important how the polyline is closed i. The code doesn't make any check about the selection, so if you select something else other than a polyline you wil get an error message. If all you want to know is whether a Polyline [or Ellipse or Spline or even Circle] is closed, you can do just this:.
That returns T if it's closed, and nil if it isn't. But the OP is looking for where it's open. This is not complicated. If he doesn't want to play with PEDIT and Edit vertex option, then he can select the polylines, loop through them and place some dummy entity, like an "X" string text at one or both of the end s of each polyline, sometihng like this:.
I think it should check for whether each Polyline is closed, and only add them [or it -- probably just one at either the beginning or end would be enough] to those that are open. That makes it a little more complicated, but not very. If they merely want to see where the openness is for a given Polyline, I still go for the select-it-and-pick-in-the-Vertex-slot-in-the-Properties-Box approach.
I verifyed that the default text height was set to a visible value. I pasted the shape into a new clean drawing and attached it to this thread.
Am I missing something? And yes, this is exactly the type of routine I am looking for. Clicking on properties and changing the Closed value to yes works, but it does not show the designer where his geometry was invalid.
But I would point out that there might be other pieces of Text with "X" as content that they might not want removed. It's certainly quite a bit shorter, but then you very often seem to find longer [sometimes hugely longer] code more "elegant" for some reason I've never been able to fathom.
Also, ssdel is only "destructive" if you have a need to retain the selection set for some further use. I can't imagine why they would in this situation, if the routine marks all the offending objects and not others in the set. Now if they would want to remove the closed ones from the set, and keep only the open ones, and retain that reduced selection set, that would be different, but it would still involve ssdel.
It's not using PEDIT that's time-consuming; it's selecting the Polyline and grabbing its grips one by one and dragging them, I assume to try to locate a vertex that isn't hooked to the segment on one side. For those that "look" closed but are not, using PEDIT and its Edit Vertex option, or the Vertex slot in the Properties box, immediately shows you where the starting vertex is, which is the only place that the openness can be in such a situation. That's why I would put in only one piece of Text, if that's what they want, which could be at the beginning or the end.
Two of them, in the problem situations, would be on top of each other, or at least so close to one another that they would be redundant to [to quote the OP] "indicate where the Polyline is open. But there's no difference for a capital X. Is the current Text Style one with a defined [non-zero] height? If so, take one of the "" Enters out of the Text command. The way I process the selection sets using ssnamex Compared with the scholastic way, it has something fresh, I can not explain it to, you but I know some people here will understand.
It's like people playing chess by the book and applying allaways the rules and combinations they learned, compared with talented and imaginative players which will stand out from the crowd and imagine surprising solutions.
Or you can ask your son, I am sure he can explain you about original, elegant and concise mathematical demonstrations and solutions, compared with beaten paths. How to change line to polyline in autocad?
