Trace reference is really slow!!!

Anonymous — Thu, 12 Jul 2007 20:28:53 GMT

Every time I turn on trace, I have problems.

Whenever I do anything, even if I click on a line or element, it starts to think for at least 30 seconds.

Does this happen to everyone? Trace is a awesome and very powerful option but not like this, it is completely USELESS!

Please anyone offer me some advice.

(I am using a PowerPC G5 with 1 gig/ram, dual 1.8 Ghz)

I'm using dual 1.8 and dual 2.0 with 1.5 GB of RAM and they do not seem so slow. It can take a few seconds if you have a section/elevation because it has to rebuiild when you first show it.

What sort of video card do you have ?

Apparently there is an issue with AC11 and nvidia 7 and 8 series cards.

My nvidia 6600GT and trace works fine but on my other pc with the 7900GT as soon as trace gets turned on it slows down dramatically.

Talking to retailer here, graphisoft are ment to be releasing a patch soon.

It's working fine for me when tracing other model views or DWGs on worksheets. But when the trace ref is a PDF or image file, everything slows down quite a bit. This is most likely due to the size of the PDF or image file I guess.

My video card is a nVIDIA GeForce FX 5200. Others in my office are having the same issue. Every time I try to pan around the screen or zoom it has to redraw everything.

Under the "options" menu, I went to "Project preferences" then "Miscellaneous." There is an option there called "Update autorebuild model viewpoints continuously." I turned it off and it still is no better, it is still updating.

Is this a problem with my videocard?

I've never used a pdf as a trace reference before.

Are you trying to trace reference a "view map" item? If you are referencing a view with a different layer combination than the current window, it will do that.

The way to get around that is reference from the "project map", which will not change the layer combination. Of course, that means you won't see some things (such as roof on the exterior elevation if you are on the plan layer combination).

It may need a bit of a different layer organization to do exactly what you want, but in general I believe it's fine for referencing 2D xrefs, 2D drafting views, etc. It's also great for referencing the layout view. This eliminates the need for a grid object for me.

DENNIS!!!!

Thank you, that works!

I was using the view sets as trace and when I went to the project map it now runs flawlessly.

They should make you a senior member......

and the new hotfix addresses 2 or 3 speed issues !!

I did not know that this was the case. I had to read it for myself. Here it is:

The use of View map items as Trace Reference
If you wish to use e.g. an elevation as Trace Reference under your floor plan, you can do it in two ways:

Select the elevation in the navigator’s Project Map, and select “show as Trace Reference”

Select the elevation in the navigator’s View Map, and select “show as Trace Reference”

In the first case, the Trace Reference will use the same layer settings and model view options as the active view. In the second case, the Trace Reference and the floor plan will use different layer settings and model view options. This latter scenario will result in a slower 2D rebuild, because the refreshing of the Trace Reference involves changing layer and model view states. So, if possible, use Project Map items instead of View Map items as Trace Reference

I know there are many other reasons to upgrade to AC11, but I thought the Plan + Elevation (as View map trace) was a nice feature. I did not know of the Speed hit.

Thanks Steven - no, really, I'm really just stumbling along here w/ everyone else - I hope "they" make me a beta tester first though...

Thanks to you all.

I finally get it. I didn't understand the difference in speed between view and project map reference.

Selecting from project map is just like using good ole' ghost story...
nice and speedy.

I've followed all of the suggestions on this issue and it is still slow... (think my mac is dying a slow death)

Another tip not mentioned here(unless I'm blind?) - not sure how much it will affect performance though - try adjusting the information shown on the Trace reference - go to the Trace reference pet palette, click the black arrow and check/uncheck the elements required.

using the trace tool just slows everything down, sounds good but not yet working. i see the sugestions for using project map references and not view sets, but this should not be the case, if the option is there, it should work. whenever you move around the screen with a trace reference on i can see the quick options pallette scale settings flipping between 100 and 50, it seems to be reading or checking the scale.
Also, with trace on, when you zoom in to place a mesh, both cursor and stretch line disappear completely, so you have to place node points blind.

I've noticed all of these symptoms, as well as a problem with being able to select items in the active view. The visual problems are workable, but the functional ones are not! I have a pretty fast Xeon workstation, so it should be as good as it gets!
