Creating a mesh

Anonymous — Thu, 25 May 2023 15:14:58 GMT

Looking for a little help... I am trying to build a mesh for the first time. I have the shape of the site created, no problem. What im looking to do is somehow translate my imported jpeg site plan with contours onto the mesh. Can I draw the contour lines on top of the mesh as a guide and then spec an elevation for that line? I guess I would need to add nodes to that line....

Yes you can.

Draw splines over your jpeg contours so they extend past the edges of your site. With the mesh tool active select your mesh, then space click on each contour. Then select one node on a contour, select the "z" elevation button, give it the appropriate height (check the "apply to all" button) and do this for each contour.

Hey presto, you're done.

Of course, those contours are just interpolations - based in coordinates created by a survey.

If the contours are complex, you could inadvertently create too many nodes on extreme contour curves.

Better to use the actual survey coordinates if you have them, to keep the polygon count down on the mesh element.
