Sawtooth Roof

[Wes Goforth]

I'm trying to create a sawtooth roof on an existing factory building model. But, I don't know how. Can anyone direct me to a tutorial or other guide to this operation?

Thank you.

Draw the 2D plan view of each of the roof faces in Top/Plan View. Then use the Roof Face command to convert each of these into roofs. If they are all the same size create one and then use either the Move by Points tool in Copies mode or the Duplicate Array command to create the others.

Thanks very much, Mike. I believe I can do that.

Do you have any guidance on creating the sawtooth brick parapet wall that forms the elevation of the end walls?

I appreciate your response.

To create a sawtooth in a wall, use the Reshape tool in a 3D view to add "peaks" to the wall. Do a search for "wall peaks" in the Vectorworks online help to see how.

[Wes Goforth]

Thanks again to both.

And if you want to do the truss/Space frame.... well simply you can't.... thats been a wish list item for some time now. HTH

Heres a nice revit feature that would be welcomed in VWD

If the wall is 'under' the roof you can use the AEC>Fit Walls to Roof command.

And if you want to do the truss/Space frame.... well simply you can't....

.....well actually you can....try using VWs quite powerful 3D modeling tools together with its very usable hybrid symbol functionality...works like a charm, at least until they get round to making a parametric tool with this type of functionality.....

Do tell..what powerful 3D modelling tools are you referring to (for trusses)?

I was refering to the ability to extend and trim Struts/Ties to the chords (Video)...or am I missing something new...

[VincentCuclair]

Ah, you mean extrude along path and then edit path length......i'm not saying VWs has a dedicated truss PIO but it is possible to draft this and fairly easy to edit them.

I've used that truss/space frame tool in Revit and it probably takes as many mouse clicks browsing through dialog boxes and different settings as it takes 3D modeling it in VWs.

Basic Workflow:

1. You need to create a new Family for the truss

2. Draw the truss with 2D lines (oh like in VWs extrude along path!)

3. Select the type of profile to use (oh like in VWs extrude along path!)

4. If the truss exists of different profiles do steps 2 and 3 for each profile.

5. Exit path mode

6. Save component

Editing:

7.Select truss

8. Activate edit mode in family

9. Enter edit mode for path (oh like VWs)

10. Edit 2D lines that make up the path.

11. Exit 2D edit

12. Save as or replace family component

13. Insert into model.

OK, you don't need to change the 2D representation, that is the advantage of parametric objects....but don't say it is not possible.

Ive posted the you tube Revit link above why dont you provide the eqivalent VW processes/steps since you think they are identical... and LOL,dont forget the manual 3D boolean operational steps in VWs for trimming the members.HTH

[VincentCuclair]

1. Build truss using the correct 3D beams approx. 8 steps incl. mirror copying.

2. Select all diagonals, trim using split tool. 2 steps

3. Done approx. 6.5 mins

Want to edit? Double click the beam and edit beam type, split positions and/or beam positions....

And if you want to do the truss/Space frame.... well simply you can't....

Well I stand corrected...Thanks for posting Im still on 2010 cant wait to try it in 2012.Just curious,Is there a new 3D (extrude/project2D) tool similar to connect and combine in 2012?

Thanks again

[VincentCuclair]

No, actually I tried that first but it didn't work, that would be a very nice addition though. I was however surprised that the beams were still beams after i chopped off their ends, i expected them to become solids.

Btw it was the first time i've used 3D beams, originally i planned to use extrude along path in the otherwise same workflow.....
