    Artistic Touch Needed for Rendering

    Thanks Sean. I have saved the SimLab file. Still too new with the app to know if it included the materials, etc... The forum will not allow me to upload a .sim file so here is a link to the drop box I put a copy in for you. This i7 cpu is at least 4 years old. I don't recall when I rebuilt it but it's definitely now a newer one.

    Artistic Touch Needed for Rendering

    Thanks again everyone. I have figured out the issues of getting the model into SimLab Composer. It's really cool and much faster at rendering than AutoCAD. Now, here is a very simple model which I am still having trouble with. The model in AutoCAD with materials applied and the sun turned on is just a dark box with a lid. Honestly, I don't remember AutoCAD 2014 doing it like this. But it's been a long time since I had to render a model. The top lid on this model is supposed to be steel diamond plate. So I applied the material Polished Diamond Plate, and then I tried just plain diamond plate. When I run the render at high resolution all I get is a out of focused bluish plate. No diamond tread plate pattern appears on it. And as per my original complaint, the image is blurry, out of focus and is just not acceptable for what I'm trying to achieve. Several years ago when I was using 2014 and the materials library that came with it, I was getting much more in focus and sharper images. Okay, switching back to SimLab, I get a slightly better image with it but still the tread plates doesn't show up. Even if I apply the materials from SimLab the tread plate does not come out like I need it to. The only results I got which came close was the diamond plate pattern but it was tiled and not uniformly spread across the plate. I know that rendering is an art form and what one person achieves is not necessarily the same another modeler would end up with. I've used another environment which I used back in the 2014 days with three lights setup at various angles, two in front and one from the back side. That setup worked great back in those days, but here I'm still getting the same blurry, out of focused imaged with nothing at all like the resolution I was getting before. BTW, this computer is an i7 with 8 GB RAM and it has an Nvidia Qudropro FX 380 graphics card. It's about 9 years old now but it's the same card I was using back in the 2014 days. Any advice would be greatly appreciated. Steel Box.dwg

    You can say that twice. I installed a copy of SimLab's trial version. Gotta learn how to use it first. I imported the dwg file and all I got was a few of the angle shapes. On top of everything else, the last render I was running just choked this i7 cpu with 12 GB RAM. Was typing this reply (which was lost) when the computer just shut down cold turkey. I think the power supply in it is old, like me.

    Thanks for the reply. I never heard of SimLab but I'm reading up on it and installing a trial copy this morning. I guess what I'm still unsure of is what really happened between the old rendering engine and the new one AutoDesk chose for AutoCAD. Did I somehow miss something? I'm not and expert at rendering but I do a decent job at it. I can't seem to get the desired results using what I'm thinking are the exact same settings I used with the earlier versions of AutoCAD. The renders produced in 2019 seem to be cloudy, not clear and crisp as before.
  5. I have created a 3D model of a steel assembly in AutoCAD 2019 and it looks good. The preliminary renderings I'm doing with it are nice but I'm noticing a couple of things. Years ago when I was working with AC 2010, 2012, etc... I was doing similar renderings and they seemed to be much clearer and focused. With this new version of AutoCAD I am noticing what seems to just be a blurry image, of fog if you will. I never tweak settings like fog so I'm not sure how to remedy this. The materials I have been applying to this model are quite simple. Just some galvanized and stainless steel. But when the rendering runs at the level I've set, the image just doesn't come out with the crispness and focus that I am expecting. That said, I'd like to ask some of the more experienced rendering people here if you could offer some advice. I'm using lights instead of the sun. You can see how I set them up in the file. Any advice as to how I can get this rendering to pop off the page with a little more clearness and plizaz will be appreciated. AC Render Testing.dwg

    Need Advice for Gutter Layout

    The details were made, the metal fab shop was issued a purchase order and they made it so perfect that it slid together like snot on a door knob. The iron worker who doesn't speak English that well told me he understood perfectly. Then what did he do. Instead of engaging the two parts and sealing them he butchered it all up and butt jointed it. Of course it leaks like a sieve and his explanation is he didn't understand the drawings because they were in English....$500 worth of brake metal down the tubes and we're back to square one.
  7. I am always very envious of the renderings I see others do. For some reason mine end up kind of crappy looking although they present the general idea. Here is one that I created tonight and would like to ask for help from anyone who has the special talent to make this look more like a photograph than a stone sculpture. It's a huge file and I've saved it down to 2013. Too big to upload here so I created a link in my drop box account. Any advice or help would be appreciated. https://www.dropbox.com/s/pldaz1tot3iki26/3D%20Stair%20Model.dwg?dl=0
  8. I need a little advice for a sheet metal application. The attached drawing shows a gutter profile I need to layout. It's supposed to have a 2% slope but if I use that (1.15°) it slopes right past the boundaries of the area I will be installing it in. So I'm choosing 1" for the short side and 3-9/16" for the long side or where the down spout will be. In trying to make a 3D model of it I used EXTRUDE and then Taper Angle, but it won't work that way. I was able to use the LOFT command but was wondering if anyone with sheet metal experience has a better way to lay it out with the following parameters: The overall dimension I need to cover is 15'-6" but the longest piece my supplier can make is 120" so I will need to use 2 pieces with a 3" overlap. This forms a box, if you will, 8 total pieces making up 4 sides. The corners need to be mitered but I think that will make sealing the corners a little tricky and it will leak. Gutter.dwg

    TABLESTYLE Text for Title & Headers

    Thanks again BIGAL. I'm using the latest 2019 version of AutoCAD so we're going through install issues for the moment. But I'll get a chance to look at this more in depth later tonight.

    TABLESTYLE Text for Title & Headers

    BIGAL, Here is one of the blocks I'm trying to work with. What I would like to do is to be able to select one or many of them and have a data table built like the one in Lee-Mac's Text Count program. It works but it also counts the "FE1.1" fields which is not what I'm after. Drawing1.dwg

    Rusty LISP Skills

    Trying to dust off some code here for a new project and finding out how rusty I've gotten with LISP. So before I go to my real question can someone tell me why this works: (defun c:sk (/ dxf ent) (defun dxf (code ent)(cdr (assoc code (entget ent)))) (if (and (setq ent (car (entsel "\nSelect an Attributed Block: "))) (eq "INSERT" (dxf 0 ent)) (= 1 (dxf 66 ent))) (while (not (eq "SEQEND" (dxf 0 (setq ent (entnext ent))))) (princ (strcat "\n\nAtt_Tag:" (dxf 2 ent) "\nAtt_Value: " (dxf 1 ent))))) (princ)) But this doesn't (defun c:sk (/ dxf ent) (if (and (setq ent (car (entsel "\nSelect an Attributed Block: "))) (eq "INSERT" (dxf 0 ent)) (= 1 (dxf 66 ent))) (while (not (eq "SEQEND" (dxf 0 (setq ent (entnext ent))))) (princ (strcat "\n\nAtt_Tag:" (dxf 2 ent) "\nAtt_Value: " (dxf 1 ent))))) (princ) ) (defun dxf (code ent) (cdr (assoc code (entget ent))) ) The only difference is that the 2nd defun is outside of the first one in the version that does not work. I have seen code like this before with defun's inside of the main defun but never really understood it.

    TABLESTYLE Text for Title & Headers

    Hey BIGAL, yes I found that was the trouble with my testing of the code. I changed the value of the variable bname to be the name of the block I'm testing and it worked, but not with the results I was looking for. I'm examining Lee-Mac's TCOUNT code because it's more of what I think is needed which is a simple text search. The trouble I'm having with it is that the code which counts the text also counts the text I don't want to include. For example, I'm using a block which has two attributes attached to it and I'm only after one of them for the data table. I'm also looking at the DATAEXTRATION command as several articles I've read promote this as a preferred method for accumulating counts. As always with AutoCAD there is more than one way to accomplish a given task.

    TABLESTYLE Text for Title & Headers

    Hey BIGAL, thanks for the code example. I'm looking it over now. But when I tried it out it fails at this line:

    TABLESTYLE Text for Title & Headers

    Fast-forward 1/2 hour and I did find the variables to change the text in the data table. That's cool. Now to figure out how to by pass the 2nd attribute of each block... Fast-forward another 45 minutes, got the pizza delivered and now I got a 3rd column.
  15. I need a way to accurately and quickly count objects in an AutoCAD file and once again, our main man Lee-Mac has an excellent example called TCount which fits the bill nicely. Here are some additional features I could use some advice on for expanding it. The detail call outs I'm counting are a block which is a circle with a horizontal line through its center. The block contains two attributes, the top being the Mark # of the part, and this one is the target I'm after, and the bottom attribute being the sheet number. The sheet number is not of any interest at this point so I would like to know if there is a way I could omit these instances showing up in the data table. The TABLESTYLE command is useful for getting the font set to the size and colors I want, but the text in the Title on the Header fields is rather generic. I'd like to know if there is a way to change the text, beside editing it manually after the table is created. Doing it with the LISP code would be fine or to be able to set the desired text in the TABLESTYLE window would work as well.
