I have imported a site plan in dwg form wich will form the basis of a housing layout.

I have been trying to use "topofsurface" to create the area which is going to be the site of my intended visual.

However, when I use this function it is NOT creating the shape as I require.

The shape I want is almost a crosss-shape yet the topofsurface function is filling in the gaps between points thus creating more of a squar shape?

Is there a way of specifying the detailed points to create a site plan??

Here's hoping you more experieinced Revit users can help.

I don't understand your problem description - an image would help.

You can create your own topo surface.

Here's an image

I am trying to follow the red line but you will note it creates an image based on the blue line as it skipping some of my intermediate points.

I hope the picture tells a thousand words!

Or putting it another way, I want to create a surface for an ordnance survey plan, similar to the one attached.

What is the best way - it will basically incorporate road, turf, planting and fencing - not too difficult I imagaine!

As a very experienced Chartered Surveyor and someone who has built many properties, I think I am fully aware of the distinction between "property and topography" and do not undertsand why you are pointing that out??

I apologise if I am not making much sense but I shall try one more time...

Having now imported an os plan I wish to work it up in 2 parts - one being the property (which I am able to do) and the other being the site (or topography if you prefer to refer to it that way)

From the inported plan I obviously have the reference points for the boundaries but to my knowledge, this does create a site from which we can apply materials such as grass or tarmac.

So, I want to create that site surface from my imported plan from which i an apply materilas and then site my property on top?

Does this make any sense????
