Display Lock, Locking the view

[cadman6735]

Is there a way to lock the model when using drafting lines?

When detailing an elevation view or section view or callout for example. Is there away to lock the model down (without pinning) so that the model is not accidently modified while drafting. I am getting complaints that drafting on top of a model is cumbersome because users accidently select pieces of the model (that can't be seen because it is behind a wall) and blindly modifying the model while detailing. Is there a way to stop this?

Thanks

Only by educating the users. You can use the Pin function, but this will have unintended consequeces in other views. What are they "trying to draft" over the elevations?

They are detailing enlarged section views, call outs and such using the model as a trace.

I only ask because we use Mstation as well as ACAD and Revit. And Mstation has a feature to turn display lock off for referance files. You can still see the xref, you can snap to the snap points when desired but you can not move or delete the xref in any way.

This seems to be a good feature for detailing model cuts in Revit. Nothing worse than windowing a chair in elevation view and grabbing half of the model behind the wall.

Anyway I was just wondering

Thanks

One of the approaches to this issue is the use of worksets. IF the chair is placed on a furniture workset, and that workset is turned off in the wall sections, then the chair won't be selected in that workset. That was one of the original intended uses of worksets, to help cpntrol this selectability of objects. IF they select in a different view, or a 3D view, where that workset might be on, then switch to the wall section, they can still inadvertantly cause problems.

I have found myself too wanting to 'lock' the model, this time during dimensioning, so I didn't inadvertently pull some walls around due to sloppy mouse work.
And thanks for the forum guys, nice to see people helping people.

Once I have finished the conceptual stage of a project (or at the earliest time possible) I will create grid lines which are dimensioned & the dimensions are locked making an individual grid line immovable. I would then align the walls to these grids and lock them. Having done so, the principal wall elements within the model are locked and I can get on with the tasks of finishing the cd's without worrying if I have knocked something out of it's correct position.

If I need to move something at a latter time, (client has asked for this wall to be move 100mm!!?? ;-) ) I would hit the "activate dimesions" button which will show all the locks - unlock as reqd, move the wall and re-lock asap.

mmmm I wonder where the activate dimensions button is in 2010 - better go and look.

This is a good approach, provided that you will not be collaborating with any other party using Revit. We have found that locking the column grids and exterior walls, then sending it to the say structural engineer causes untold grief down the road. When they copy/monitor your grids, the grids copyied into their file are "locked" as well, and even more difficult to unlock. Just keep that in mind before sending them a file to begin the copy/monitor process on.

Also keep the same thing in mind if you have multiple users in one office working in the same file. Locks and constraints are very powerful and can be very beneficial.... If EVERYONE on the project knows where they are and why.

MANY times ive watched fairly new users go to "move a wall" only to grap it, activate the move command, dictate a 1'-0" move, and then look at the screen and see that... Nothing moved. Then they will move it AGAIN. Nothing moved. Typically, after the THIRD time, they will go get help. If its an unlucky day, in an effort to qualm whatever issue is at hand, theyll go down a routine like "undo, undo, undo, move, move, check another view, move, STC, move, move, check another view."

All the while, it IS moving, its just taking EVERYTHING locked WITH it, so it doesnt seem like its moving.

Im telling the story that way to be funny, but it DOES happen. We had an exterior wall type that was being held to a certain dimension from the Struct. CL to the outer face of the wall. This was- of course- derived from the wall makeup, and the necessary space for the framing to clear the structure. When someone ACCIDENTALLY edited the wall type definition, the walls grew INWARD towards the struct, since they were all located on Exterior Face Location Line (it really wouldnt matter, we were checking both dims anyway). Well, they went to move the walls OUT the corrective distance (they didnt realize the walls had been altered), and the walls wouldnt move.

No, they WOULD move, and take the entire projects structural grid with it. Hehehehehe...

Another way to manage this is with your far clip offset. You can set it such that anything beyond the specified range becomes "invisible." It doesn't help in section if you need to see things in the distance. However, for interior elevations and call-outs, I try to make my far clip offset be somewhere in the back wall of the room, so I can't select anything in the room beyond.

Throw in some curved walls, and dimensioning within floor plans, not just exterior, and this procedure wouldn't work terribly well for me. I do some sessional teaching and an Introduction to Revit is one subject. Students just love sloppy mouse work. I get the idea though, and will try it out.
thanks
