Blocks Performance in V7

opening a very simple dwg from autocad with a few floor plans the viewport was almost unmovable when zoomed out for an oversight. zooming in into details increased the speed to kind of normal.

the same file opened in rhino 5 works blazingly fast without changing a thing. so i found out that it contains a couple of blocks, 84 to give it a number and after exploding them the viewport reacted normal in V7.

i can not share the file since its confidential, at least i can show a low res screen shot to give you an overview of what i am talking about.

maybe it is related to this topic

The only way to really examine and tune performance is by looking at models like this. How does the V7 performance compare to V6?

yes, rhino 6 handles that file pretty good without having to explode blocks.

so i created a random file in V7 with a few lines and hatches and about the same amount of blocks and i felt no laggy experience, so maybe really something particular with this file.

once i explode the blocks in V7 the performance is almost on par with V5. while zooming with the wheel on the mouse in and out feels just the best on V5, V7 is not far behind (it just takes a split second more to zoom at least it feels a bit slower) and definitely better than V6.

what i also noticed is that some text does not get loaded in V7. i will send you the file via PM.

It seems V7’s block processing needs much improvement.

I witnessed similar issues which is being investigated.

i actually saw that topic but i could not find it anymore, thanks for referencing it.

Hi guys,
I just have to mention that since jumping to R6 and R7, 2d blocks are slowing down the performance dramatically. Even though it got a bit better. But sadly for us, blocks for us are not an option nowadays. Was pointing that out here Curve block - performance

(Not mentioning the problem with a draw order, that blocks suffer from.)

same here, we cannot use R7 for our architectural projects!! already bought 2 licenses …
Please fix ASAP !

I will post a file for reference later…

best

It’s get laggy when opening files dwg files with simple blocks in r6 and 7 also

mmmh, the extreme lagginess is gone after the latest release candidate update… still seems to be slower in R7 though, which it really shouldn’t IMHO.
