Co-ordinate system and query tool
-
I would definitely like such a tool. When working on archaeological sites, we do our digs to an orthogonal (national) co-ordinate system and querying certain points according to this system would be extremely cool. There are tens of thousands of kilometres in the system however so take it into account that it would not be just some centimetres (since Bob is in the engineering field).
Also if you think of something, it would be ideal if this data were saved with the file (so I do not need to load every time I open it) if that is possible. Or at least an option to "feed" the file from a simple text file (like Didier's cloud.rb) so after opening the file and loading the coordinates, everything would work fine.
Also, moving things by absolute co-ordinates with the
[x,y,z]method in the system would be very good. -
I've written it already and will post it shortly in a new thread. Its link is here http://forums.sketchucation.com/viewtopic.php?p=284829#p284829

If you want alternative 'units' formats I can look at those too... Currently it uses the Models current units/accuracy settings. You can convert selected text to tags as explained in the notes so importing a points cloud and using a simple tool to turn cpoints into text [I have written one here already?] then turn those texts into coords-tags...

Can't the request be accomplished by selecting all the entities in the model, then placing the "Axis" where ever you want it?
-
Are you suggesting moving the entire model so that 0,0,0 is at the desired datum? bob did acknowledge that as an option but suppose you have a number of parts for which you want to create the X,Y table. The datum point for each part will be in a different place so you would have to move the model for each one.

I saw that; guess I don't understand the request.

Often, when you have a part that needs to have a large number of holes drilled in it, rather than using dimension lines to identify the locations of those parts, an X,Y table is created. The coordinates of the center of each hole are given in the table as referenced from some point on the part. That point might be the top, right corner for example. The x and y distances from that corner are then given for each hole.
I've done SketchUp models where I was given the X,Y table and used Didier's Point Cloud plugin to insert construction points for the centers of the circles I need to draw. Bob is asking for the reverse of that.
I couldn't find an image of the SketchUp model but I was able to use the X,Y table and Didier's Point Cloud plugin to draw the holes in the green and the black plastic parts shown here.
There are a number of other parts for this machine for which I was able to use the same process.

OK, thanks, I understand you. Isn't each component's, data points relative to the component's origin? Typically the component's
boundingbox.min? Is that what Bob is looking for?Wow, you slipped in that nice piece of equipment.

It is a nice piece of equipment. It's the go to machine in my shop.
If you place construction points at the centers of the circles/holes in the component and click with the Leader Text tool on those points, it'll give you the global coordinates.

In my case, moving would not be an option as I would be some 800 kms away from the origin and you know clipping.
TIG: thanks a bunch; I am going to look at the plugin right now.
