Sea Level in Elevation and Section

GDL Enthusiast — Tue, 25 Feb 2025 01:56:29 GMT

Hi,

I am hoping to reference the Sea Level height of the project in the elevation and section views. I have tried and searched without success. The best I have is

ObjectHt = int(SYMB_POS_Y*1000)

This returns the height of the object in the Y-axis relative to project zero. Is there any way to find the Sea level, 1st or 2nd Reference levels in elevation and section views?

Many thanks, Matt

Could you REQUEST ( "REFERENCE_LEVEL_DATA", "", name1, elev1, name2, elev2, name3, elev3, name4, elev4 )? 4 should be sea level.

Do note that the value is in meters and is the distance below Project Zero to Sea Level hence would typically be negative. So for your sea_level_height, you would minus elev4 * 1000

Hi Ling,

Thank you for your response, it prompted me to look at that script and I realised I had used SYMB_POS_Z. I would have given up, but thanks to you it is solved, so appreciated! Wishing you all the best, Matt
