How to define a new level marker?

[Anonymous]

I come from China. I can not find the level marker type we used in Level Tool. So I have to define a new one myself.
But how? No subtype for level marker.

Anybody know?

Are you referring to the "Level Dimension Tool"?

AFAIK, it hasn't changed much since AC7.0. Right now, as it has been in the past, the dimension indicator symbols are hard-coded (not customizable ). Maybe the next version will allow new custom "Level Markers" similar to the "Section Markers" now available in AC8.*.

Or, am I not understanding your post?

You understood quite well, thanks.

I think I have to use Object Tool to insert level marker.

Wolf,

You are right that you need to make your own level dimension markers with the object tool. The good news is that you can make them better than the Level Dimensioning tool does. I made one that changes its appearance according to whether it is used in plan or section. It automatically picks up the elevation above project zero in section and it displays the z-height in plan (allowing auto slab, roof and mesh spot elevations using the gravity feature). The only limitation is that they can't be linked to other model elements so they have to be manually updated when things change.

If you like (and any others of course) I can e-mail you the part to adapt to your own needs.

Matthew,
I don't know how to use the gravity feature in my level dimension marker. Would you like to tell me about it?

Thank you, very much.

The gravity setting is in the coordinates palette (see attached image). You can set it to slabs, roofs or meshes and it allows an obect or wall (or other 3D element) to be "dropped" to the correct elevation to sit on a roof etc. This is especially handy for placing trees etc. on a site model.

To use the gravity feature with the level dimension marker use the global variable SYMB_POS_Z as the text for the marker. This will display the height of the part as it is placed in plan. The attached jpeg shows a plan window with spot elevations "dropped" onto a site.

In elevation use SYMB_POS_Y since the elevaton window is a 2D view using x and y axes. This global will always return the height above the project zero (it is not affected by moving the origin). The jpeg also shows the same library part used in section.

Matthew- How did you get the text to display in the elevation view?

[Anonymous]

It's the smame as in plan view (Text2 statement in the 2D script) except using the SYMB_POS_Y instead of SYMB_POS_Z.

Howdy gents. My search returned this old thread as the closest to my current dilemma. I’m trying to figure out the best way to place markers that will display top of wall elevations in plan. I don’t care what tool is used to generate these but would like to have them linked to specific walls. It appears that the Level Dimension tool is out since gravity does not work with walls An Object based marker cannot be associated to another element AFAIK, so that leaves the Label tool. Is this a correct assessment? If so, can someone please point me in the direction of the proper code to transfer parameters from the wall to the label. Thanks.
