Project "Transparent Envelope" as Help for virtual construction using MLCad |
Posted by: Arthur Sigg - 2012-11-07, 19:53 - Forum: Help

Available
Relative complex object which fits in a volume of about 20 x 20 x 20 cm
Target
Building this object from Lego in a scale of 1:2.5 (volume about 50 x 50 x 50 cm) using MLCad, LDView and LPub
Possible Solution
(1) Scanning the object
(2) Scaling Scan Data (1:2.5) and saving as object.stl File
(3) Converting object.stl to object.dat using program STL2DAT
(4) Integrating object.dat in LDraw Library (under Models)
(5) Temporary mod of LDConfig.ldr by adding a more transparent color "Trans_Clear_Clear" (just done)
(6) Positioning object.dat in MLCad and assigning the new transparency "Trans_Clear_Clear"
(7) Building the model inside the transparent envelope with best fit (checking with LDView)
Need Help
(1) I do not own a Laser Scanner and 123D does not delivery usable results so the object has to be scanned by a external Scan Service. What have I to observe placing the order ?
(2) What do you think - would the relatively old program STL2DAT be able to convert the STL file delivered by such a Scan Service using modern hard- and software ? I do not really understand the options I have to use with STL2DAT - how can I find out best values ?
(3) I added the more transparent color "Trans_Clear_Clear" temporarily to LDConfig.ldr by copying existing definition for "Trans_Clear" and changing CODE to 48 (unused color) and ALPHA from 128 to 100. It seems for me that ALPHA is a measure for the transparency - what is the usable (allowed) range of this value ? (e.g. 64 does not work)
Thank you for any recommendations,
Arthur

Tube segments (166.dat, 80.dat) and edge lines |

I just noticed some of the segment parts (166 and 80) seem to have edges on the inside, is this a technical thing or an oversight? I's seems like a waste of resources to me.
I'm worrying about this because I want to use those files as donors for generating seamless tubes (deforming the segments along a path) the result can not use references so it will generate a ton of flattened geometry, including all those unnecessary type 5 lines.

Hey,
Here is the new and stable LPC 1.4.4!
Please uninstall older versions of this software before installing a new version.
Your configuration won't be deleted if you have already version greater than 1.3.1 installed on your machine.
Change log:
New features: - The opacity configuration is stored in the lpc file.
- You can use shortkeys for all snap & merge actions.
- The Colour Palette+Image+View Prefs forms are minimized, when the main form is minimized.
Fixed bugs from 1.4.3 and older:- LPC crashes on file export (with included projection data).
- The "Advanced Options.."-Menu causes a crash under rare conditions.
(see full list of tickets for 1.4.4)
I included a short readme.htm in the installation directory.
Cheers & Leg Godt
Nils

Hello,
I am pretty new at using Leocad and am having trouble finding one of the parts I need. I am looking for part #6087. Here is the bricklink reference page for the part;http://www.bricklink.com/catalogItem.asp?P=6087
Am I just not seeing it or is it not in the parts library?
Thank you for any help.
