Default very noob question but here goes:

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.

Default Re: very noob question but here goes:

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!

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!

Default Re: very noob question but here goes:

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.

Default Re: very noob question but here goes:

Ok here goes,



1.Use the outline tool to draw a simple square with more vertices for one of the four corners as shown below! TIP: Using the gridsnap feature in the bottom left if very hand here!

2.In the "Vertex select mode" select the second to last two vertices using shift click, its quite important you only select these two for now!

3. Begin resizing the vertices and moving them about and you have a nice looking curve! its easier than you think! TIP: switch OFF gridsnap to get a smoother curve!

4. This is where it can become tricky, still in Vertex select mode, select each verticed 1 by 1 in a clockwise motion, with that select the Vertex Menu > Create Ordered Surface,

with this select "object select mode" and select the object menu > Optimize surfaces.

6. Now using a similar tech to earlier, select the same two inner vertices in the drag them down just slightly, and move in and do the next two and then the remaining one. T

this is so cool of you.
you can view some of my work on my website. www.matthoyle.com
i'm a professional photographer who utilises 3d as backgrounds for my people shots.
i currently use vue infinite for my backgrounds but i'm currently building a new york street.

i've done a series called 'cinemaricana' and 'fairy tales' with completely 3d backdrops i created.

i'm going to give a good look to your tutorial and let you know how i'm going.
thanx again for taking the time.

matt

Default Re: very noob question but here goes:

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!
