Loading model based on SEL_ITEM

[brent.g]

Hello everyone,

I am currently working on some code that involves tracking down parts that are the owners of views and determining if they are loaded or not. This part is already done. What I am looking to do is modify the code such that if a part is NOT loaded, then it will be automatically loaded from the database.

Currently the owner is found with:

PHP Code:

display(first (oli::sd-am-inq-all-3d-owners)) ; returns first in list no problem 


(In our company it is okay to assume all drawings have the same owner)

Next, we check to see if the part is loaded

PHP Code:

display(oli::sel_item-p(second (first (oli::sd-am-inq-all-3d-owners)))) ; this part works fine, if T then part is loaded in sd, if NIL part is not loaded 


(I am straying from using variables so that people reading this can use the code right off from annotation)

Now I know it is possible to load a part if you have an identifier or an elid, for example:

PHP Code:

(oli::sd-db-element-load :identifier "650-11362" :database-type :model) 


My question is if it is possible to load an element from the same information which is collected for determining if the part is currently loaded. For example I tried (don't laugh):

PHP Code:

display (oli:sd-db-element-exists :identifier (second (first (oli::sd-am-inq-all-3d-owners)))) 


This doesn't work, but this is the idea. The identifier as I understand is the name of the part in the database. I do know how to get the name of the view:

PHP Code:

display(oli::sd-am-inq-name(first (first (oli::sd-am-inq-all-3d-owners)))) ;;currently returns name 


But not the name of the part, so if someone knows how to do this bit, it could work.

Anyway, I will quit typing and see if someone knows how to help. If any of this is confusing feel free to ask and I can elaborate.

Thanks,

Brent

Alright, so I think I am getting close here. I am still having an issue with just one message (see attachment)

The following works when the part is loaded:

PHP Code:

display(oli::sd-inq-obj-sysid (second (first (oli::sd-am-inq-all-3d-owners))))
 
; returns 969500-1298388487-2564b217ac-0 14266
 
display(oli::sd-db-element-elid (second (first (oli::sd-am-inq-all-3d-owners)))) 
 
; returns CARP8R2XC8G2F0 when part is loaded 


Now if the part is not loaded, the previous two lines return the lisp error "969500......14266 is not a structure" (see image) I know that the sysid can be found when the part is not loaded:

PHP Code:

display(second (first (oli::sd-am-inq-all-3d-owners)))
 
; 969500-1298388487-2564b217ac-0 14266 is what gets returned if the part is not loaded 


But why am I getting this "not a structure" error? Why can't I use this sysid with the database (model manager) to get more information? Does anyone know of a way to call to the database with a sysid and get any kind of information back when the part is not currently loaded?

Any insight is appreciated,

Brent
