Section viewport render slow

[MKingsley]

My section viewports seem to be taking a long time to render in hidden line w/ objects displayed behind the section line. I just clocked 9 minutes to go through six layers in a file that is 29 mb. I have some furniture and fixtures from the VW libraries and less than 20 simple extrudes and solid subtractions. Vectorcaching is on as well as "Display viewport cache" for the viewport. Is this what other people are experiencing? My machine specs are below.

Viewports, thus Section Viewports, do require a bit more time to render than objects on Design Layers take to render.

Are you seeing a significant (more than 30%) time difference in the two?

I just rendered a layer link in an iso view with the same layers in hidden line and it took 2 1/4 minutes. So the section VP in hidden line takes 200% more time to render.

It would be great if Viewports were always updating in the background using the processor downtime to do so. For most of us the processor isn't working much apart from when we are rendering in a design layer. The time it takes for some Viewportts to re-render is horrendous. Have half a dozen updating and you almost have time to go and make a cup of coffee.

I like Mike M's suggestion. If I'm not using the processor, then VW is welcome to it!

Slowness of section viewport updates could be (a) because of 3d conversion resolution setting - set it to low or medium if you do not have many curved details in section vp. (b) section vp update does a litle bit more than just updating the rendering, in certain instances it actually recuts the design layers and reconstitutes the cross-section - which might take more time than just rendering a scene.

Excellent! Thanks for that, Biplab. That made all the difference.

BiplabNNA,

I seem to have consideralble "jerk-i-ness" to VP's when I have more than one VP per sheet with lots of hatch, fill, lines, text and dimens in the VP annotation.

Any....thoughts.......

After all I've run out of nails to drive into my forhead.

I've got some extra nails if you need them.

Very funny illustration -- it feels....just.....like that.
