api to delete all entities on a particular layer
i am writing a macro to remove proprietary information from our drawings before we send them on to our customers.
my steps are as follows:
1. turn all layers off, except the ones to delete.
2. select all entites remaining through this code.
dim swentity as sldworks.entity
dim swent as sldworks.entity
dim selmgr as sldworks.selection manager
do while not swentity is nothing
swent = swentity.select4(true,selmgr)
swentity.delete
swentity=swentity.getnext
loop
i cannot get the "select4" to work.
3. turn remaining layers back on.
i have steps one and three down, but i am having problems with step 2.
thanks for the help

what errors are you gettings? is it coming up with a "with or variable not defined", is it returning "nothing", etc...?
also, you need to change your select4 statement to:
swent = swentity.select4(false,selmgr)
else you will be adding to your selection constantly
the error is "value of type 'boolean' cannot be converted to 'solidworks..interop.sldworks.entity'. here is my complete code for reference.

firstly your main problem is that you never get the first entity of the drawing to start with, instead you get solidworks itself.
secondly, you have no need to select4 the entity once you have it.
thirdly, the selection returns true or false, not the selected object so you cannot set the entity by selecting it, and you have already set swent at the top, so remove that line completely.
and finally, there is no call for entity.getnext; an entity is the base class for nearly all sw objects so it isn't that simple; an assembly is an entity, a drawing is, and a part, so by trying to delete all entities you would fail to delete the drawing itself. also, entity.delete does not exist either.
effectively your entire loop is invalid. you are much better off being more specific and looping features not entities, or finding out exactly what it is you need to delete, because you need to be able to check the visibility of the objects also.
ok, now i have worked out the process for deleting annotations and dimensions. the code to do this is as follows. my next issue is to delete the sketch segments. what is the most efficient method to traverse the drawing and select these segments?

your best bet for drawings is to traverse the feature tree and delete based on type:
swtncentermark = "centermark"
swtndrsheet = "drsheet"
swtnabsoluteview = "absoluteview"
swtndetailview = "detailview"
swtnrelativeview = "relativeview"
swtnsectionpartview = "sectionpartview"
swtnsectionassemview = "sectionassemview"
swtnunfoldedview = "unfoldedview"
swtnauxiliaryview = "auxiliaryview"
swtndetailcircle = "detailcircle"
swtndrsectionline = "drsectionline"
swtnbomtablefeature = "bomfeat"
swtnholetablefeature = "holetablefeat"
swtnrevisiontablefeature = "revisiontablefeat"
swtnweldmenttablefeature = "weldmenttablefeat"
swtngeneraltableanchor = "generaltableanchor"
swtnholetableanchor = "holetableanchor"
swtnweldmenttableanchor = "weldmenttableanchor"
swtnrevisiontableanchor = "revisiontableanchor"
swtnbomtableanchor = "bomtemplate"
for example checking only for centermark items...:
set swfeat = swpart.firstfeature
do while not swfeat is nothing
if swfeat.gettypename2 = "centermark" then
swfeat.select false, -1
swpart.editdelete
end if
set swfeat = swfeat.getnextfeature
loop
obviously i haven't put any error checking in there.
luke, these are great, but they don't handle items that are part of the drawing such as lines and arcs that are sketched on the drawing and blocks
unfortunately not, but they cover some for you. to do what you are after you need to combine many loops, for features, for annotations, and for view items etc...
i remember seeing code somewhere that traversed a layer and deleted everything except images. i don't think it was this long.
