View construction steps


Hi,
is there a way to view a final construction from start (step by step)?
Only two buttons: forward and backward.

Thanks

Hi,
i follow another way...
First, open the Construction Text window, select all the objects and hide all; then select the object in sequence (one by one from first) and show it.

Now a question:
is there a cindyscript function to select all the objects (ordered like in Construction Text window)?
With this function we can write a script to view the construction step...

Thanks.

best regards

Indeed, that's a good idea. The function 
allelements()
gives you the elements in the desired order. And you can use the .visible property to make them invisible. For example, the line

forall(allelements(),#.visible=false);


will hide all elements. If you need further help, let me know.

Hi,

you can use undo/redo for this purpose, but this does not work with constructions you load from a file. Other than that there is no such functionality, unfortunately.

Best regards
