Wow, this is exactly what I want to learn how to do. I understand building the texture ok, How big was your final geometry for the board? Thank you, this is excellent help.

Wow, this is what I want to do. Very nice job. Thanks, I will give it another try. I think I was selecting vertices vs edges.

I do not know how to bookmark this thread but I have often referred to it. Not everything makes sense the first time you hear it ...

I was wondering if there is an option to just reduce the vertices without redrawing the circle? Somewhere I saw one of the Blender gurus on YouTube select select alternating vertices and delete or dissolve edges. I tried the approach described in this video and it didn't seem to work. Using Blender 2.8

I want to figure out how to apply the board texture and then join the parts to the board as Aquila suggested. I have images of the front and back of the board as well as connector textures that I want to add. The Arduino is an open source design so there are other versions used by people.

I have not begun adding textures but for the IC I would probably just add a black material. The only texture needed is for the board top and back and the connectors, I think ...

I think you go above and beyond my expectations to answer my questions and I really appreciate you in depth help and advice. The use of the STL files can be a pain but if we can find ways to use them for SL there are a floodgate of new models that can be used to enhance the virtual experience. This forum and you are amazingly helpful I and I really appreciate your time and effort. Thank you ...

Thank you so much for the advise. I am not sure I know what you and Chic are talking about regarding "Joining", is that like appending in Blender or Linking in SL? Yes, some of the parts have are too complex. I had already deleted the tiny holes (vias) in the board. Was not sure about how to reduce the reduce the number of edges in the 4 large holes. Already have started to work on reducing some of the geometry on the two end parts (USB and Power). The IC is a total mess. I can also remove some of the other fillets and chamfers in the model. Thanks again ...

I understand your comments and appreciate you taking the time to respond. It is sometime difficult for me to understand the significance of some of the SL upload values. My objective is to find ways to use CAD drawings in SL without spending a lot of time reducing geometry or recreating things. For this example I downloaded a model from GrabCAD and started to reduce geometry in Solidworks and Blender. I picked the model that was the least complex (some part models are away to complex but I will tackle the obvious things first). In Solidworks I delete the vias (small holes in the circuit board) and un-needed fillets which reduces the mesh by 76% of the original vertices, edges, faces and triangles. In Blender if I use the Mesh Clean-up for Merge by Distance, Degenerate and Limited Dissolves I can reduce by at least another 40%. I have used Decimation in the past but I first want to simplify the model as much as I can. I will continue to work on reducing the mesh. Regarding adding textures I understand that I can only have 8 materials. That should not be a problem. I need black, red, light gray, and maybe the Arduino board color (blue or aqua). Not sure what you mean about "JOINED", is this something done in Blender with an "append" or linking objects in SL or something else?

This model has these metrics: Upload Fee 37 Land Impact 27.57 Download 27.57 Physics 4.6 Server 0.5

Moving on to the next piece of the puzzle I wanted to upload an Arduino Uno board that is very popular in electronics right now. We use it in many of our school projects and I wanted to upload a 1 meter version for students. I found a model on GrabCAD and downloaded it and converted it to an STL. The model has more geometry than is needed but I am not sure how to simplify some of it. https://pasteall.org/blend/6adef1fd1d8c4dea982090ef1b53cc42 Any suggestions? Thanks ivytechengineer

When you extrude from a face and you enter a negative value it becomes an extrude cut. I believe this is what has happened to my ramp. I want the extrude to go into the model not out from the model.

Thanks, the Sl Browser was in a region that could have K-12 students and staff present. I will pass the info onto the region owner... thanks again.

Is there a way to lock the SL Browser down in SL? I was just at a K-12 site that used the browsers and some one had changed many of the URLs to inappropriate sites.

That works, thanks. I originally drew this in Blender and thought that I could extrude a solid from a face but for some reason it creates a shell verses a extrude from the face. I can follow your suggested approach but why doesn't Blender extrude? OBTW, if I select the vertices I can do a fill and create normal faces...

ok, I thought it was something like that. Thanks

Sorry, I have a follow-up questions about the ramp model I created. I wanted to see how it would look like in SL so I uploaded it to Opensim but it doesn't look to good. https://pasteall.org/blend/bcab95fb96a34d88854d97323eb3028a Not sure why all the geometry is not visible if I am right next to it. Suggestions? Maybe its a limitation with Opensim? Thanks

Can I export my SL avatar to for Opensim? My Avatar is one of the SL New Avatars, can this be exported?

You can use Firestorm for both. Opensim can get installed on your computer and you can access it via Firestorm or another viewer. It is free.

I wanted to post the latest DC Motor model that I have created with help from Arton, Chin and Aqulia as well as some others with the scripts like Roling. It looks and works great. Thank you for all your help. https://www.ivytechengineering.com/SecondLife/files/DCMotor.gif

Sorry, I figured it out. I thought it would be more tricky

Thank you Chin and Aquila, I appreciate your help. I thought I had used the resolved this issued with some Mesh clean-up but I missed this one.

I was able to create some new ramps with trusses that look pretty good in Blender. Need to add some materials and they should be good to use. Thanks

I have been trying to reduce the mesh for my mountain model and I think I am almost there. I used the high LOD for my physics model and now I get a MAV_FOUND_DEGENERATE_TRIANGLES error and it says see the SecondLife.log for details. Question 1 - where is this log file? Question 2 - So SL said "The physics mesh too dense remove the small thin triangles (see preview)" but when I look in the region highlighted in Blender I see no small thin triangles in Blender? https://pasteall.org/blend/971dbb99795d465c88a53b9711e5f09a
