Section perspective? is it possible?

[vivace_rahl]

Hi there.
Im hoping someone can help me out with something

Is it possible to create a section perspective in revit? I was able to do a 2d section and also a 3d section using section clip box but i was wondering if it is possible to do a perspective instead?

Another qn. is, is it possible to edit something 3d in drafting view?

And last, how do i shape the edge of concreate beams to match the floor edges?

THanx in advance!

Could you elaborate the questions?

Yes!!!

Just create the camera view you want to see the section in. Then in the view properties, chose Section Box and enable it. When you go back to the view, you will be able to stretch the box, which cuts out anything that is not contained in the box.

Enjoy!!!

One way to acheive this would be to set up a camera in a plan view with the approxiamate view you are interested in. In the new camera view that opens adjust your crop region to see all of your model. In the view properties check on the section box. Selecting the section box will provide you with drag handles which can be used to section your model.

THanx in advance!Drafting views created from the View tab of the Design bar are usually used for standard details either drawn from scratch using linework, detail components, and filled regions or traced off of imported legacy details from another cad platform and can be referred to with cuts/callouts on the plan. You typically need to use the section, callout, or elevation tools if you want changes to be reflected back to the model since these are live views of the model itself.

THanx in advance!Could you provide an example of what you are trying to achieve here?

Beat me to the punch Luigi . . . I guess I type slower with the kids hanging on me at home :-)

There are some PDF examples in this thread, is this what you're trying to do?

thank you so much! Now Im able to see a perspective section. thankx again!

Abt the beams. for instance... my floor edge is curved. I want to run a beam from a column in the center of the floor slab...towards the edge of the floorslab. since the edge of the floorslab is rounded...Its ugly having my beam jut out with its sharp edges. how can i profile the beam edge to match the floor slab edge?

This is an illustration to show what i mean. The thing is.. i can edit the edge of the beam using family editor..but i have alot of diff types of edges...which means..its going to be tedious. any other methods?

You can create an "in place component" which would just be a void to cut all the ends of your beams.
1. Go to place component, select "create in place", make it a generic family or a beam family.
2. Create a new void extrusion, the plan of it will have 1 edge which trims all your beams, the rest of it can stretch out into space, that part doesn't matter.
3. Finish the sketch but not the family and go to an elevation view to make sure that it's tall enough to intersect all you beams.
4. Next select your void and use the "cut geometry" button (a white rectangle over a blue rectangle) to associate the void with all your beams.
5. Finish family.

Am I right or wrong?
Peace,

[Andre Baros]

Hmm, your right. I can't cut the beams when I test it. I guess if you use the draw it the way you build it idea you have two choices: Stop all the beams short of the edge, or create an "in place" beam family and cut it right away.

I am also looking to do a section perspective (not a 3D cut-away).

What I want is to create a SECTION view (including grid lines, level lines, filled regions & annotations) and convert it into a ONE POINT perspective view. Ideally the cut plane would be to a set scale, say 1/4".

I have attached a few pics of what I would like to achieve... these were not created in Revit, but I would like to be able to reproduce this type of drawing using Revit.

Any thoughts? or is this a wishlist item?

Those can easily be done. It's just a matter of where your camera is positioned to get the 'one-point' look. Drop in a camera, then on the bew 3D View Revit creates, you can use View>Orient>To Other View, and pick your Section from the list.

[jontramos]

Thank you, I didn't know about the orient to view feature.

It works, but the problem is that I don't have the ability to use any of the tools from the drafting tab, nor do my grid / level lines display (because it is a perspective view)

Also, there is no way to control the scale of the drawing, usually I would draw the plane of the section cut to scale.

oh, and also...

I am forced to use the section box to create the cut, which is very limiting, because it is not view specific. As I understand it there is only one section box in the whole project, and I only have the ability to turn it on or off. I can't create a different section box cut for 3 different section perspectives that I would like to create... essentially I would have to move the cut box each & every time I need to see the cut away in my view.

no, section boxes are independent...one in each view. don't get Section Boxes and Scope Boxes confused! You can create as many 3D section-perspectives as you like, and adjust each Section Box independently.

If you orient view to section, Revit puts the cut plane of the Section Box at the same plane the section line was at, and at the scale of the view of the section. Annotations (grids, levels, etc) wont show up, but you can overlay a section view wioth annotations on top of the 3D section Perspective on a sheet. The examples you showed did not have any annotation?

I must be missing something, because I cannot get this to work in a perspective view. It works perfectly for a 3D view without the camera turned on, but I sure can't figure out how to do it in a view with the camera turned on.
