AutoCAD 2010 :: 3D Reflectivity And Glossiness
Feb 5, 2013
I have a question about 3D rendering in Autocad 2012. The image attached to this post has three objects with different presets using mental ray. From right to left the reflection varies from perfect mirror reflection to a diffuse reflective surface.
I've been struggling with Autocad to render diffuse reflective surface but every time i use reflective and gloss in a non metallic material the result is always mirrored. When objects are illuminated with a white point light the white color should cast and reflect in the materials in a diffusive way, unless the material has a glossy finish.
Can i get diffusive reflections in objects such as the example in the middle or the one in the right of the picture of this post or do i have o use other program for final photorealistic render?

I can't quite get the effect I am looking for. I have a flat plane mapped with a standard reflective material that has a transparency map. I'd like the transparent areas of the map to disappear and not have reflections. I'd also like my lights to be excluded from the reflections. I tried to exclude my light group using the "local exclude" button in the reflection map, but nothing changed. I've also done tests unchecking each box withing the material editor to see where this can be controlled.

When working with a 3D layer, I cannot use any textures besides the diffuse texture at the same time as using the render setting "Ray Traced". For example, everything works great when the render setting is set to "Solid": I can use a high quality glossiness texture and even a bump map. But as soon as I juice up the render settings to Ray Traced, Photoshop freezes up, and I have to force quit it through the task manager. The texture being used is high rez, as in 8192 by 4096, but the same freeze up occurs on a smaller texture of 2000 by 4000. Any ideas on why it glitches up so horribly?This first image is the objects 3d settings, I have both a bump texture and a glossiness texture enabled.When I change the preset to from "solid" to "Ray Traced",

Maybe you remember post about caustics issues with iRay:

I've noticed new issue with iRay: When glosiness of refractions is lower than 1 the SHADOW isn't correct - looks like casted by non-transparent object.
I'm sure it's not caused by "non shaped" light source, I've tried with daylight system and with Photometic shape-visible light.
I've attached ZIPped file to illustrate that problem, and a test renderings I've made.

I'm doing a program in Visual Basic 2010. In one of the forms I put a button that when clicked must open AutoCAD 2012 and make a drawing in it. The user will decide where to save it.The steps are these:
1. I added the references Autodesk.AutoCAD.Interop and Autodesk.AutoCAD.Interop.Common to the Visual Basic Project. That's OK.
2. I wrote this in the heading of the form's
- Imports Autodesk.AutoCAD.Interop
-Imports Autodesk.AutoCAD.Interop.Common
3. In the event Click of the Button1 I put this:
Dim acadApp As New AcadApplication 'Create an instance of an AutoCAD Application
AcadApp.Application.Visible = True 'Show the instance of the AutoCAD Application
Dim acadDoc As AcadDocument 'Create an intance of an AutoCAD Document
acadDoc = acadApp.Documents.Open("C:Respaldo TesisDibujo2.dwg") 'Open a Document called Dibujo 2
'Draw a line
Dim PT1(2) As Double

Our company just upgraded to AutoCad 2011. We get files from our clients that exports their files from revit. It seems that Autocad 2011 slows down when reading this files (cursor will have a second or two delay).

I'm using AutoCAD Mechanical 2010 and received a .DXF file that contains 'solid' objects. Unfortunately the next tool in my workflow doesn't understand 'solids' only polylines (and a few other basic shapes like circles, lines, etc). Is there some way to convert the object in AutoCAD?
I tried the 'boundary' command but when it asks to 'Pick Points' and I click inside the solid, it always gives the error 'Valid hatch boundary not found'.
What am I missing here?

Trouble with embedded OLE DWG objects in word 2010 not opening with AutoCAD 2012
We have a user that can't open some OLE DWG files from within a word document. He had 2010 AutoCAD LT on his machine for a while then was upgraded to 2012 AutoCAD (non LT) once that was there LT 2010 was unistalled. since then he has not been able to open certain embedded OLE files within Word. Other users that have other ever had AutoCAD 2012 have no issue opening this embedded DWG files.
i found this thread (URL....) which sounds exactly what is going on with my enduser. But the fix provided is for AutoCad 2000-2012 not the LT versions.

I am using autocad 2013 primarily and other employees are using 2010. I am saving my drawings as 2010 and for me there are no issues. On the other hand people using 2010 are having objects missing in the drawing. All layers are turned on and all thawed. The primary objects missing are AEC objects. Is there a switch to show or hide these object?

I recently loaded several versions of AutoCAD on to a Windows 7 machine. ALL versions will open a drawing if double-clicked from windows explorer, but if I try to open through AutoCAD, the program freezes as soon as I click on the "Open" button. This is true for AutoCAD 2010 through 2012.
Machine Specs:
Dell Optiplex 990
250GB HD
8GB Ram
I7-2600 proc
AMD Radeon HD 6670 (1Gb) Video Card
I also cannot open multiple instances of ANY version of AutoCAD in Windows 7.

I am finding the layer combo control in 2010 an annoyance. The drop down box does not access as many layers as did the version in 2009, and I find myself continually searching through the drop down box to reference a particular layer. How to rectify to have it similar to 2009?

Publishing files using Autocad 2012 with a page setup to plot to PDF files. I am utilizing Autodesks "DWG to PDF.pc3" file. But I have to go and manually rename the files to remove the "- Model". Is there a way to change this while publishing? Or am I stuck with this file naming convention?

Just loaded 2012. When I go to plot, the plot style table drop down can't find any ctb's. The "plot style table search path" in options > files, is set to the right folder. I've tried convert, convertstyles, ptstylepolicy and nothing works, Why can't Acad find the path with the ctb's.

When you start a new drawing, you use a DWT
When you insert a pagesetup/layout, you use a DWT
When you insert anything else (like your default layers into an existing drawing), you use DWG.
However, in the described case... the DWG would basically be the same as the DWT (as it would be your default layer setup, or have your company styles etc), so you would create the DWG by going to new and then save immediately.
What bothers me about this is that you then basically have two files... which should be one file - or at least they should be linked: version control.
How do I make sure, non-manually, that the "template DWG" and the "template DWT" are the same, remain the same etc? Or how do I eliminate one of the two?
AutoCAD Mechanical has the "Drawing Setup" utility to import a DWT - am I just overlooking a similar option in Vanilla?

I have a problem with lines that begin and end outside the Z is zero, and polylines with elevation outside the Z zero. The difference is very small, for example, -0.00000112, or 0.00000078. I checked the possibility of using the Flatten command but does not always work, even though there hatches in the drawing. Polylines and Blocks also cause problems with the command by flatten.

We are using Autocad 2012 and 2012LT in our office and with this version started using the built in feature of DWG to PDF. One issue we have come across is, if we create a pdf file and then need to recreate the same file we can not overwrite the existing file. We are forced to either give the new file a different name or go back and delete the existing file prior to creating the new one.
