why does the topo move when I scroll in

I've used a point cloud to produce a 3d model, and inserted a 2d topo,

 

but when I scroll in the location / position of the topo shifts rendering it useless for checking my model to as indicated in the attached images,

 

scrolled out the red topo line is to the left of my object, scroll in its then in the right position, scroll further then it sits to the right?

 

how do I insert the topo so it doesnt do this, please?

 

Ive inserted it and also referenced it into the file with no change

Really hard to understand what you are describing. What do you mean by "Scroll"?  Let's start there.

I think by "scroll" they mean "zoom in using their mouse wheel." I have also noticed this can make non-orthogonal lines from CAD and other linked or imported files move around a bit when zooming in. I'm curious to hear what you have to say if this is indeed what the original poster means.

Yeah, it doesn't ring a bell for me, and I'm very well-practiced with Point Clouds and Toposurfaces.  Only thing I can think of, is that the Revit content may be placed way too far from the Project's Internal Origin.

Does toggling Hardware Acceleration on and off change behavior?

yes thats right @Redrunner92  when you use the wheel on the mouse to zoom in and outscrolled outscrolled out

these are the differences of the topo that you can see in relation to the model on site, I cant tweak the model to the topo as the topo moves!

 

I'll have another loot at the origin, it was drawn centre to centre in the first instance the topo was inserted after , and a northings and eastings added, but even removing these made no difference, 

 

 

also just double checked my topo import and these drain covers were drawn squared off, now they are a bizzare shape,

Im getting to the point now , I'll just insert a pdf of the topo and see if that can use that to finish off the project

Based on your description and the fact this is being seen in an imported/linked DWG, if I had to guess you are working a long way from the internal 0,0 origin in Revit. That would manifest in behavior like you are describing. I would check that to see if some how you are working "out in space" somehow.

 

Find the Project Base Point in a plan view.  Is it close to your geometry?  If no than you might be in "outer space".  If it is, right click and select "Move to Internal Origin". If the project base point still close to your geometry?  If no, then you are in "outer space. If yes, then your problem is something else.

The developers built the theory of gravity into Revit?? That's awesome!! And would explain why the lines move more freely in "outer space"! :sich_vor_Lachen_auf_dem_Boden_winden:

outer space can also be translated into " the out skirts of butt fuc nowhere" which is really un-useful

 

but will take another look it this origin issue

Maybe this will be more "useful"...

I’m sure I’ve installed everything centre to centre to try and avoid this issue , but no harm checking these elements to locate the source of this issue , appreciate the link thanks

ok it was the topo cad insert , co-ordinates miles from the 0,0,0, point, copied and pasted into a fresh drawing at the 0,0,0, point and now the topo appears perfectly in revit

So, bottom line;  what was the solution?  Sounds like it had to do with what  @loboarch and I suspected.  Were you exceeding Revit's maximum distance limit?  Did you have elements in "the out skirts of butt fuc nowhere"?

it wad the topo being the pain, as it was set to gps co-ordinates, I inserted at center to center, but the computer still recognized the northings and eastings, so effectively it was in the middle of butt fuc nowhere

 

quick solution, after checking  the project base points , was to copy and paste the topo into a clean drawing with no co-ordinates an re-insert 

 

job done , just doing the last sweep of the project now
