Please help with rendering

[peterg]

Hi all, can anyone please help with rendering? Completely new to rendering so need to start at the beginning, using Autocad 2007. I want to render in 2D, as I have only used 2D.

 

any help or directions to where I can find help would be appreciated.

You render solids and surfaces in 3D. There is no rendering in 2D just like "there is no crying in baseball."

Well Remark is correct, no rendering in 2D but you can use solid hatches, hatch patterns and gradient fills to achieve similar results. Let me jump into the "wayback" machine and post an image I made back in 2004 using AutoCAD 2004 showing what can be done with creative use of fills, colors and the super hatch command found in the Express Tools...

I told you we had some very creative members didn't I? If I didn't then I should have.

 

Nice one there f700es.

[peterg]

This is very similar to what I want to achieve, now the question is, how can I add "patterns" ie woodgrains with colour????

I am using Autocad 2007. I am trying to draw lift car interiors, wooden panels, formica panels, stainless steel finisher etc. definately a step forward, many thanks.

This is done with the superhatch command in the express tools

[peterg]

Thats great f700es, but can you explain the process for this or point me towards a tutorial that explains this, also how do I get the "pattern" to fit the the item to be hatched. I am sure it is simpler than I am finding it, just need a bit of direction.

 

Many thanks.

Do a little searching on CADTutor http://www.cadtutor.net/general/search-results.php?cx=partner-pub-7131253896966208%3A601f8l7rk5g&cof=FORID%3A11&ie=UTF-8&q=superhatch&sa=Search&siteurl=www.cadtutor.net%2Ftutorials%2F#1026

It works best with tileable textures. I'll try to write up something if those links from SLW don't help.

Still struggling to understand Michael Beall's instructions. To simplyfy what I am trying to do.

If I down load a picture from the internet (colour picture of wood grain), how would I then save this to use as "superhatch" in different parts of a drawing???

 

I am sure it will be easy after I have done it a couple of times, just struggling to understand the process at the moment & no one to show me.

Why can't you just use some kind of woodgrain hatch pattern (.pat file)?

Is this what you are trying to accomplish?

 

 

The small (12x12) wood grain hatch pattern was grabbed off the Internet using "Save target as" (jpg). I brought it into AutoCAD using the ImageAttach command. The large (24x36) pattern to the right was created using the same jpg and the SuperHatch command. When presented with the SuperHatch dialog box I selected Image as the pattern type.

 

If you go back and run through Michael Beall's short tutorial about using SuperHatch following the example he provides then you'll have a better understanding of what is being done. It took me two attempts. I'll give you three. Now GO and DO.

[peterg]

Exactly what I want, cheers. Will try & let you know how I get on.

Well good luck then. Post an image when you're done. We like seeing other people's work. It gives us something to talk about.

Managed to get to this, but this is not righr, not happy with all the black borders, where have I gone wrong???

 

[ReMark]

You forgot to set TFRAMES to "off" is probably what happened.

How is that done??

[ReMark]

Really?

 

You can do it via the command line by typing TFRAMES.

[f700es]

Ok here we go.

Start by having the drawing ready to receive the superhatch.

 

 

I added the image to show what texture we would be using.

Run the superhatch command and then select your image file. It will ask for the placement of the image. I started with a lower left corner of one of the panels.

 

 

It will ask for a scale factor. The default is one and for my image (a larger one) this will be fine. ACAD will then show the placement of the image and ask if this is OK.

 

 

Next it will ask to select the interior location of where the texture is to be applied. Select the interior of each panel.

 

 

Follow the prompts and you will get a image like this.

 

 

Next I usually select the image frames (white lines in the texture) and move these to a hatch or image layer (you all know me and layers). I then select the image frames and use the draw order command and move then to the back. Then you can turn the image frames off using either TFRAMES and IMAGEFRAME commands.

 

You should get this...

 

 

Using this command and color/gradient fills you should be able to get a nice 2D image.

Good luck

Also you will want to use a seamless texture. There is a nice tool included with the current version of Gimp that will take an image and make a seamless texture out of it. I used this on this texture before using it in ACAD.

 

Edit: also try to use true color for fills and gradients. These will print in color no matter what pen table you use.
