Wondering if anyone's found a solution for the following:
Let's say you're modelling a building. The designer usually gives you blueprints with relative levels. That is, there's an arbitrary zero, and then your first level is 0 mm, next level 3500 mm, etc. Works pretty straightforward in Tekla, just set up your grid.
Let's say you're modelling a structure within a project which is mainly infrastructure. Could be a control center for a pipeline, a building within a port, something of the sort. The designer gives you blueprints with geographical altitudes. So, your first level is 900 meters, your second level is 903.5 meters, and so forth. Might even be more abstract, your first level 909.3 meters, your second level 1002.8, etc.
That one gets complicated. All of a sudden your grid is at 900,000 mm altitude. Just placing the grid gets me, since when you enter Z=900,000 as the origin, it moves completely out of the work area and out of sight.
So, what's the best way to go about this? I figure I could simply say 900 meters will be my zero and then convert all the rest of the altitudes to that base, so as to work with low values that won't go off my visible area. But that would mean converting all the reference levels I'm given in blueprints, with the risk of eventually placing an element where it's not supposed to go, etc.
Is there any shortcut in Tekla to get around this problem? I figure I'm on the right track by setting the origin to 900.000, but I can't figure out how to get to my grid once it goes off the work area. It seems to disappear completely.
