Trim command slow in VW 2023

[JMR]

Hi all,

 

The trim command is extremely slow with VW 2023. Trimming simple, planar lines takes several seconds now, although not every trimming event.

 

Anyone else run into this?

I just tested 3 lines and one intersecting line and it was so fast I could not tell.  This is VW2023 SP3 on a Mac.

It seems to have something to do with the trimmed polyline location..."outside" the building the trim command works fine, inside it becomes very sluggish. As if it was looking for some unseen geometry. There are no spaces or other objects at the same location that I can find.

 

Trim in a blank new file seems to work flawlessly.

 

A bit odd.

To determine if this is a deficiency in the software of Vectorworks 2023, you'd need to perform the exact same operation with the same file in previous versions of Vectorworks. Try exporting your file to Vectorworks 2022 and testing it there in exactly the same way. 

 

Many operations must first determine what objects are subject to the operation and which ones aren't. While I am not privy to the software code Vectorworks uses to perform this operation, my knowledge of how software in general works and Vectorworks in particular, I'd say that this operation takes longer to process when the objects to be trimmed are surrounded by other objects due to the strategy employed to detect whether a line should be trimmed or not. If a different strategy was employed it might be faster when surrounded by objects and slower when not. It's all geometric calculations and all geometric calculations are math; so it's all math! Give the computer a bigger equation to calculate and you can expect it to take longer. 😁
