Linetype - How to catch errors

146 Views, 2 Replies

When I load the linetype file


'' Load the Center Linetype
acCurDb.LoadLineTypeFile(sLineTypeName, gstrc_SFR_LineType_FullFileName)


How do I detect if the linetype is in the Linetype file? How do I do my error checking here in the ACAD way? 


Currently I just search the acad.lin or sfr.lin Text File to see if the LineType Exists. This works.


But I was curious how would you check the linetype file via the Acad API,

to see if the linetype definition name exists in the file?

Try/catch, resorting to the CONTINUOUS linetype hard-coded into AutoCAD in the event an error is thrown.

If you are going to fly by the seat of your pants, expect friction burns.
Adopt. Adapt. Overcome. Or be overcome.
A good question will be halfway to a good answer.

or, with reference to the example from the developers guide, open the linetypetable and check whether linetypetable.has(linetype). in addition to reverting to any particular linetype - which may be perfectly fine - you can check for alternative linetypes and/or load a particular linetype file.
