  Interactive Town Scene

I know I have posted this before, but I've been making the Datsville HD render more interactive.

[Image: 49555063436_7519970cec_c.jpg]

https://mjhorvath.github.io/Datsville/do...n-map.html

You can click on the buildings (only one so far) and a popup blurb will appear with a message from a Datsville resident.

Not sure how much further I will go with this. It depends on how much I can automate the process, since I plan on making further revisions to Datsville itself too.

  Help me figure out a math/measurement problem
Posted by: N. W. Perry - 2020-02-16, 4:57 - Forum: Help - Replies (5)

I found a measurement discrepancy in set 21004 between the LDraw version and the real thing. I know that sometimes things don't work out precisely between the two, but in this case there's a mismatch of exactly 4 LDU, and I'm trying to pinpoint why.

This involves the rotunda section with its stacked 6x6 dishes and 4x4 round plates, and the 6L axle that supports it. Here are the precepts:

  • The 6L axle has a length of 120 LDU, nominally equal to 48mm in real life.
  • As we know, plate height is 8 LDU (12 with the studs), so two stacked plates are 16 LDU high (20 with studs).
  • The center of the 6x6 dish has the ordinary plate height of 8 LDU, and the cavity adds another 8 LDU, making it equal to two stacked plates in height.
  • As a result, the 4x4 round plate sits entirely flush within the 6x6 dish.
  • Per the instructions, and confirmed in the physical set that I own, the 4x4 round plate at the top of the assembly sits fully within the uppermost 6x6 dish, and the bottoms of both that dish and the 4x4 dish should be at equal height.
  • The axle hole in the 4x4 dish is 12 LDU deep.
So, here's an image showing the problem; the axle assembly and the stacked dishes are shown offset for clarity, but at their correct vertical position:
   

As you can see, the 4x4 dish and plate at the top are 4 LDU too high, because the rest of the assembly is only 104 LDU high rather than the necessary 108. Where is that extra 4 LDU coming from?

I thought perhaps the axle hole in the 4x4 dish should be 16 deep instead of 12, but a rough measurement of the real part suggests that 12 is correct. All of the dishes seem to be modeled at their correct height, too, so the only thing I can think of is the axle. Indeed, measuring the real axle shows that it's just a bit over 47mm long, not 48. It may even be 47.2mm, leaving it 2 LDU short of its theoretical length, but that still leaves another 2 LDU to account for. Could the height of the embossed stud logo account for that (see the 2x2 round plates at the bottom), or just the natural physical play between parts?

  How to import LDCad file to Solidworks?
Posted by: Cuong Nguyen Viet - 2020-02-15, 8:16 - Forum: General LDraw.org Discussion - Replies (1)

Dear LDraw.org member!

I am learning how to simulate lego set. I tried with LDCad with its script.
I think this is the best simulate for lego set now. 
But, I saw in youtube that they can simulate lego set with Solidworks.
So could you give me some advice, how to import LDCad file to Solidworks?
Thank you! 


This video using SR3DBuilder. But the Developer was pass away some years, and now I cannot install it in my PC window 10.

  New Parts Tracker Search Capabilities
Posted by: Chris Dee - 2020-02-13, 19:11 - Forum: Website Suggestions/Requests/Discussion - Replies (2)

(2020-02-12, 6:29)Chris Dee Wrote: I can take a look at this.

That's done for the Parts Tracker File scan (https://www.ldraw.org/cgi-bin/ptscan.cgi). Multiple words are now supported and all need to exist in a file for it to be listed inthe search results. Double quoted phrases are supported and need to exist as entered. The two forms may be combined.

The search box in the Parts Tracker page header works slightly differently. If the entered word (xxxx) exists in the unofficial library (as xxxx.dat) the detail page for that file is returned. I guess now that the Parts Tracker allows the display of detail pages for official parts, it should also check for a precise match in the official library. At present if there is no unofficial file, the search term is passed to ptscan. It would be possible to make that script work differently in this use case, but it is not clear to me what it should do.

  How to add a flexible Powered Up Cable
Posted by: Hendrix - 2020-02-13, 16:44 - Forum: LDraw Editors and Viewers - Replies (2)

Hello,

I'm trying to get a Powered Up train motor with a flexible cable into my .mpd so I can build instructions showing where to run the cable.  

As far as I can tell, the Powered Up Train motor is not available in LDraw, but the Power Functions train motor (unofficial 87574) is a good approximation.  However this part does not have a cable and plug.  I understand a bit about how flexible parts work in LDCad, but I can't seem to find the right part to use to generate the cable.  None of the parts I have found seem to allow me to add guide points.  So two questions:

1)  Is adding a flexible cable to 87574 the right approach?
2)  What part do I use to serve as the basis for the cable that I can stretch?

Thanks!
