[Tutorial] Create a (TIN) from Surveyed Pts - using SU only

andymaw

That did the job! Thanks so much for that. Just got to find the time to put the guide points into SU and it should be sorted.

Cheers again

I could really, really, really do with that lisp script... but only have acad LT

How do I get a spreadsheet or comma separated x,y,z points into SU without having to actually position points manually? Is there a way to automate this?

Cheers

Hi,

Sure, use Didier's Cloud plugin; works great.

Hi all
Its getting confusing: the script is installed and delaunay2 installed.
The file is imported from an autocad file with simple points that i put in Z coordinates in acad.
When imported in SU they appears as little crosses ( cannot succeed in zooming on them to see exactly), and when i try to triangulate them, the ruby says " Some objects of the selection aren't construction points". How is this possible since they are all similar and all points?
Nothing happens then..

Is there any way i can resolve this?
I've put a sample from points ( acad) here if anyone has a hint!

thnx

Good lord!
I've found it!
3D points from surveyors are often blocks in acad. When i imported them, i forgot that, and they were in SU still components!.
A simple select all + explode solved the issue and made it possible to triangulate!

Relief!

Sorry for the buzz!

Yup - I was already starting to write this up - good that I read the very last post.

I'm trying to follow this thread to create a 3D landscape. I have the survey points or 'crosses' in SketchUp, all in the correct x,y,z positions. I selected all and exploded the components without any problem. I then reselected all the crosses, and selected the 'Set Centre Point' - but it puts a single construction point in the middle of the drawing - not one at the centre of each cross.

I'm using SU Pro ver 7.1.6860

Can anyone see what I'm doing wrong?

Grateful for any pointers!!

Hi D...

Do the other way round (provided that those components er the instances of the same component definition) as the order is important:

Edit one of them (double click)
Set the centerpoint inside in that component - now if they are all the same components, each should be updated instantly with this centerpoint in them
delete the geometry - i.e. the "crosses" - leaving only the centerpoint inside the component
NOW exit the component and explode all...
