Like if I push the lettercombination "PAS", Autocad shall purge the drawing 3 times, after that he will audit the drawing and at last he will save the drawing.

And with "LZE" AutoCad jumps from layout to layout and ends at the model but between every jump he shall first do the zoom extents command.

But if I create a lisp file for elevation = 0. With as result I only have to push 1 button and the command is running.

But because I do not know at which moment my elevation is changing to another value, I want to combine this with the autosave. Otherwise I need to push the lettercombination from the created elevation lisp file after almost every action. 

But I have created a toolbar button already. This contain the following macro: ^C^C_elev;0;0;

How do I use the Action recorder exactly? I see a yellow circle next to my aperture and the following text is standing in the command bar; ** ACTRECORD command not allowed during recording an action macro **.

With this program I can draw elements which has to do with Air Heating/ Cooling, Water supply, sewerage... Everything from the mechanical engineering side.

When I want to draw an Air duct, I first need to insert a height. Have I done that, I can draw the duct. With other functions from that program, I can say, I want a 45° bend or a 90° bend to another height.

This image shows you 2 round air ducts which cross each other on a different height.

But when my elevation value is not 0 but suddenly something else, it isn't a z-value which I'd used with the other application.

For example; I'd drawed a sewer pipe on a height of 2500, I didn't choose another height. It is possible that the elevation value isn't 0 but 1873.456 or something else. In any case, not a height I had been used.

That is why I want to combine the autosave and elevation command. To reduce this elevation problem. 

When a command is in progress and I am finished with that command, I push on the Enter of spacebar button. Also the right mouse button stops the command because of my own right-click customization.

Sometimes I push on the escape button to end a command but this doesn't change the elevation value.

The lisp-routine looks like this; (setvar "ELEVATION" 0). Would you change this lisp-routine? It does works. 

I do have a problem with the elevation variable. This variable jumps sometimes from Z=0 to an other Z value. The moment of changing is unknown to me.

I wan't to combine this elevation command with the autosave settings. Befor every autosave moment runs the elevation command first automatically.

Does anybody know how I can change this autosave variable/reactor?

When AutoCad starts, 2 lisp files automatically runs. These 2, which I've created, do change my Osnapz setting into 0 and also my Elevation to 0.

The Osnapz setting is no problem. This doesn't change. But the elevation does.

I'm using Autocad 2014

Thanks for your help
