Autocad filter selectionset

If yes, then the focus to my code from the other post for you is the LAST line:. That is, it does not matter how you create a Selection set, using filter or not. SelectAll or not. Just build one in whatever code suitable to you. For example, you can loop through all entities in ModelSpace to find certain entities and add them into a selectionset, something like this way:.

So, it looks like you need to come up with very fine-tuned selection filters to call on Select method. Unfortunately for your case, if the blocks you are trying to select are dynamic ones, you probably cannot apply block name filter, thus very difficult to select with Select acSelectionSetAll, filters, filterValues I think of a work around, which manipulate the visibility status of the block, since I am not working with dynamic blocks and not using the visibility properties at all for Xref files.

Selecting a selection set visually for the user to interact with them is fairly easy in AutoLISP using a function called sssetfirst.

It has 2 arguments, the first one you need to set it to nil, and the second one is the variable that has the selection set identification bound to it. If anyone wonders how the steps I suggested here would work or not, see this latest discussion on the same topic and my code solution. I may be a bit late, but I think I've found a mistake in the invocation with variable name. Looks like you forgot quotation marks. It should be:.

See the security advisory on the Autodesk Trust Center for more information. Turn on suggestions. If you use logical operators, make sure that you pair and balance them correctly in the filter list. The number of operands you can enclose depends on the operation. Logical operators. Starting operator. Ending operator. Begin AND. One or more operands. End AND. Begin OR. End OR. Begin XOR. Two operands. End XOR. Begin NOT. DatabaseServices Imports Autodesk.

Value Application. ToString Else Application. C using Autodesk. Runtime; using Autodesk. ApplicationServices; using Autodesk. DatabaseServices; using Autodesk. Value; Application. This is probably not practical, but it will work. See if you can figure out what it would select. There is not really all that much to these conditionals and they are very handy.

I use them mostly at the command prompt to copy several layers at once, which tends to be easier then using the filter dialog box. The following lisp routine will let you copy all the objects from two layers. We're currently revamping the entire site to bring you updated tutorials and a better user experience.
