very noob question but here goes:

[mhoyle]

hoping someone can help me on what i'm sure is very easy but can't quite seem to get it:

i want to create a street corner. for an urban scene i'm doing.

specifically i was trying to get a rectangle as my base and then curve one of the edges for the corner.

then i wanted to manipulate (push/pull) the vertices to give that organice imperfection to the corner where it dips down for bikes and pedstrians near the curb.

and i'm sure there's probably an easier way to do it but:
what i can't seem to do is after drawing a rectangle and then a cylinder which i butt up to one of the rectangle corners. i want to then merge the two together and cut that extra bit of corner where the cylinder has joined the rectangle, off. thus making a curved edge on a rectangle.

any help would be appreciated.

Do you mean like this, because it very simple and i'll explain how i did it if this is what you desire!

[mhoyle]

thanks mrsteve, i so appreciate how quick you replied.

it's kinda what i wanted but i should have been clearer:

i've attached an overhead view i made in photoshop. so it's a street corner and you know how you've got a little dip in the corner on both cross sections for bikes etc...

i kind of whited out the area i was going to make dipping down.

though i'm still trying to even get that square with a corner. thanks in advance for any guidance. i so want to understand how to get two shapes and join them.

thanks!

[mhoyle]

by the way, the way you've made the dip (for bikes and pedestrians) in your image is exactly what i wanted to do after i got my overall curb shape so thanks for that!

[MrSteve]

Your welcome, however do you mean like this for the corner curb dip?

[mhoyle]

yes, perfect.

both things you did i'd love to find out how. that's great.

specifically, how to add a curve to a square (like a real street corner) and then how to create that dip on the corner you just did and then also how to do the dips on the sides like you did earlier.

i've been trying all week.

thank you! any details would be so appreciated.

[MrSteve]

as for the dip in the side in my first image! well

1. starting with the same shape we created before, i simply extruded the sides along at the 6 intervals shown!



2. then in surface mode with select through off select the shown faces in use "Divide Loop" in the tools menu, you might need to install this plugin from here:-
http://www.supercoldmilk.com/ac3dplu...x.html#divloop
install this file in the plugins file in your program files and restart AC3D for it to work. This will insert a line straigh across the middle!



3. In Vertex Select Mode, shift the vertices shown below down a little



4. and again a similar tech to before use shift click and move the vertices about a little to get the desired shape on your dip.



And bobs your uncle, well I really hope this helps, and would be keen to see your results but i'll look in the morning but its 2.17am in england and i am knackered. Good luck!

this is great mrsteve,

one last thing. i'm on a mac and don't think i can use many plugins.

but there are lots of times where i want to create a specific area on a surface to extract but it doesn't have enough vertices. or divides in the specific area of the surface.

i understand that the divide loop plugin will do this but is there a way a mac monkey like me can create specific cuts.

thanks!

There are two immediate way i can think of. try this first,

1. create a block with 4x4x4. Using select surface mode, hit just the centre 4 surfaces.


2. In the surface menu, select Divide.


3. This will give you the more surfaces you need to play around with. You can also asdjust the vertices to suit your shape if you wish!


4.Then again in surface select mode, just select the individual surfaces you want to delete.


5. And boom you have you own holes where ever and whenever you need them!

[MrSteve]

the next way is a little trickier but it provides good results.

1. Start with a cube, not a block this time. and stick a cylinder right in the middle and just poking out the top.


2. Select both object but remember to select the cube first. Then in object menu, scroll down to "Boolean">Knife.


4. This has given you a surface replicating the shape of the cylinder.


You can also use knife and cutaway or just delete the surface after you have finished with it, because you may need to move it around! Alas I hope these help! I slept in till 12pm today,!
