Hi all

When I create a stair, for example, between the 1st and 2nd floor, the stair is visible on the 2nd floor plan. But I have to draw it, with 2d lines, on that floor plan, because the stair is on the 1st floor.
That means, if I change the stair on the first floor and forget to change it also on the 2nd floor plan, my drawing will be wrong.

That goes also for other elements, such as balconies or projecting slabs on under floors. Is there a way to show elements from under floors, which are visible from upper floors, without having to draw them with 2d lines on every single floor?

Thanks

Hi Miguel!

There are not any restrictions to switch-on several files from different stages in the same time. Except how many files can be opened in one time.
You create whole model, separated by stages, and can look on it as you would like.

Concerning stairs and similar.
First of all, and this way is the way by default, you have to place stairs in their own files, and switch the file with 1st-stage's stair together with a file with a plan of 2nd-stage. The same is true for slabs and others from under stages. In the result, you will see 2nd-Floor plan with 1st-Floor stair.
You could also use layers.
Third way - you can use associative views and show there which elements you want to see.
Of course, you can use any combination of all these three ways.

But for your case the first way is quite enough. Second and third - for some special cases.

In some cases, when you can't use these ways and really have to draw lines, you can to simplify it - just make a hidden/wired lines calculation from selected element - and you will have a base for this drawing. It is not needed to draw lines for any existing element from the bottom. And if you suppose to use it in the future - save it as a symbol or macro, to process the next drawings faster.

Concerning changes in the model and additonal graphics.
There are two main tips:
- If you decided to use any additional graphics, then keep in memory there you placed it. Or make a note in the file name. This way is very similar to users of traditional cad.
- Place additional graphics on the final stage of work, when changes will not come anymore. Of course, there can be some such "final stages" , so keep in mind a tip no.1.

Regards,
Alexey

Thank you very much for your reply, Alexey.
A previous note: I work with Allplan since 1998, using the real model to produce the plans, and 2D for the sections and elevations.
This is very versatile, as my drawings can look the way I want and I don't need to model every little detail on the model to have a precise section or elevation, as I can fine tune them in 2D.
Problem is when you're team grows, and it's very easy for someone changing a window in plan, to forget to update the views in Building Structure or to tell it to the coleague who is fine tuning them. Thus the Revit or Archicad aproach.
Back to our issue.
Tips 1 and 2 don't work well if the floor under is where the stair first start. In this floor, you use the "section in plan", so the stair is represented with one line style in its lower side, and another in the upper side (see the picture). That representation would be wrong on the upper floor.
Associative Views looked better, I only have to draw the arrow and the steps number (which Allplan could automaticaly place, by the way).
The issue here, is when the opening in the slab is smaller than the stair profile, as you can't edit the Associative View boundaries.

By the way, is there a tutorial on how to manage a project using only Associative Views instead of 2D Views and Sections?

Thanks
