T-5 Fluorescent Tube

[CadManDoo]

Hi, can someone make me a light modeled after a Fluorescent tube that is 2ft long and 2in in diameter. It's 6500 Kelvins and 2500 Lumens. Thanks

[CadManDoo]

oh it's only 5/8in in diameter

I think that is a pretty simple fixture to model... If your just starting out in 3D then it would be good practice...

[CadManDoo]

yeah to bad I don't know how to do it. Can I turn a rod into a light source?

Did you get the Autocad BIBLE you ordered from Amazon yet? If not, then google PRESSPULL command, or watch David's video tutorial on this site, which is quite good. Or EXTRUDE or SWEEP.

We all gotta start somewhere.

I think that OP should clarify if is looking to model in 3D that part or want to create a light entry that match the said fluorescent tube features for render purposes.

I don't understand those commands don't work on lights

[CadManDoo]

I can make the shape with no problem. Turning it into a light is what I don't know how to do.

[CadManDoo]

or turning a light into the shape whichever

I told you the kelvins and lumens. Of course it is a light for rendering

[CadManDoo]

Never mind. I think I can create it by turning the rod in to transparent white glass and then putting point lights along it's center

To answer to your private message, unfortunately I don’t know how to solve your issue; this is much advanced than my knowledge on render. Since your question seems a little ambiguous (thus the first solutions suggested), I just tried to clarify it. Hope that someone with experience in defining lights for render will notify your thread and be able to give you the right solution.

Try taking a look at the bottom of this page where it says Similar Threads. You'll notice that there are at least two that reference fluorescent lights.

 

Before concentrating on lighting the tube I would first concentrate on creating one. And try to make up your mind too. First you asked about a fluorescent light bulb then you mention a lighted rod. Which is it going to be?

 

While I admire your willingness to jump off the 10 meter board into a very deep pool I get the distinct feeling you don't yet know how to swim. You'll find yourself drowning pretty quickly. I'd concentrate on learning on to correctly create the geometry then worry about lights, materials, and ultimately rendering.

 

Re: fluorescent light. I can't recall if Web light is an option in AutoCAD 2009 (in addition to a Point light, Spot light, Distance light and Sun light) but if it is try using the WEBLIGHT command or looking on the Lighting palette.

 

A Weblight is commonly used for defining photometric lights, including fluorescent, low pressure sodium, incandescent, and high intensity discharge.

Look what I found!

[CadManDoo]

I can create the geometry with no problem. I'm just not that experienced with lighting yet

[CadManDoo]

This is what I've been working on

Every time I try to use one of the lights in the Tool Palettes Autocad crashes and I get this Error message: Fatal Error Unhandled Access Violation Reading 0x0000 Exception at 642be527h

which ever one works that is what it is going to be!

And i can create the geometric shapes just fine!

And yes there is a web light

The crash may be a result of the fact that the source of your software is somewhat questionable. I've heard of problems along those lines. Know what I mean?

Having spent a fair amount of time in Kathmandu 40 odd years ago, and in light of the drawing name I might add, that as far as I know some wonderful things happen when you orient your fluorescent light in such an unorthodox way. Internodal length is greatly reduced, leading to a significant increase in plant density. That 16 inch fan looks a bit heavy, you might want to try a number of smaller and quieter studio fans. The doctor is in.

 

Is the drawing you shared meant to be in inches, or feet? Must be inches, you only show one fan.
