I hope it's okay to bump an old thread if I have something new to suggest. I made a pizza (sticking with the food theme here) then:
I clicked on Split Feature ('mapfeaturesplit')
Command: _mapfeaturesplit
Select one or more linear or polygonal features to split:1 found
Select one or more linear or polygonal features to split:
There are 1 checked-out features selected for split.
Create new or multi-part [New/Multipart]<New>:n
Generate new feature ID or use existing [New/Existing]<New>:n
Would you like to Draw or Select the line for split? [Draw/Select] <Draw>
Specify start point:
Then I traced around the donut hole I prepared earlier.
It makes a new feature in the middle of the pizza. Then I selected that feature and deleted it and voila, a donut!
Well, I missed this topic, but here's a classic way without juggling.
If you wanna get a donut shape with embedded OD, the magic answer is: "topology".
I wanna to select more than a polyline at a time for update their xdata by autolisp. I am able to do it one by one but it is lengthy and time consuming.
Hi,
Look at this link https://knowledge.autodesk.com/search-result/caas/CloudHelp/cloudhelp/2015/ENU/AutoCAD-AutoLISP/file...
There you will find the description of the ssget-function to select more than one entity.
When you use the filter option you can select only ploylines. But be carefull, there are more then one objecttype for polylines (POLYLINE and LWPOLYLINE).
(ssget "_W" '((-4 . "<OR") (0 . "POLYLINE") (0 . "POLYLINE") (-4 . "OR>")))
For Filter lists you find more explanation under the following links:
