Drawing the ground

[rookie37]

I need to draw grass covered rolling hills.

 

Can I draw them without third party software such as Terra Firma?

Take a look at this thread: http://www.cadtutor.net/forum/showthread.php?8618-Contour-Textures-for-Terrains

Thankl you!

 

I'm going through it. I do have a question. Is it always techicolor or can I make green hills?

[Cad64]

You can make it whatever you want. If you want grassy hills then just apply a grass texture map.

thanks for the links...

I'm not so good at acad, can't follow the tutorials and it looks fancier than what I need or want.

 

Anyway, I played around with rulesurf. It looks about like what I want but on every contour line, the rulesurf goes the opposite way. This makes a smooth hill look like a set of stairs.

 

Anyway, I'm not set on rulesurf. I'm certain there is a better AND SIMPLE way. Besides, I don't think rulesurf will do the top of the hill

Take a look at a plug-in called 'Lands', also Acad 2011 can manipulate meshes pretty well if your not too worried about accuracy.

 

If not my advice would be to build up layers similar to a physical model using contours and the SWEEP function.

[rookie37]

Thanks. I'll look into the sweep command. How should I draw my contours differently?

[ReMark]

Recommending the Sweep command to do land contours? Wouldn't Loft be better?

sorry, meant LOFT.

[ReMark]

Well that clears up any confusion. Didn't want the OP to be yelling "WTF?!".

 

Thanks.

Loft looks good. I will probably do it that way. I have notice that I can only loft every other contour.

 

I think I'll make 2 copies of the terrain and separate them. Terrain 1 I will loft contour 1, 3, 5 and on the other terrain loft 2, 4, 6

 

I will then combine the two

[Cad64]

That doesn't make sense. You should be able to loft the whole thing in one go. Can you post your CAD file?

[ReMark]

Sounds like you are lofting two contours at a time. The profiles you are lofting should remain viable though so you can then select one of the previous ones and a new one. Try moving the solid you created to one side temporarily to see if the profiles are still there.
