have two angles with objective tool or roof?

Anonymous — Tue, 23 May 2023 12:57:07 GMT

Hi there,

I just wanted to know if there is anyway that I can angle the objective tool or the roof profile so that it inclines not only longitude but also has an angle latitude.. becuase as you can see with my images.. the pots gradually increase so i need a roof like material that can be at an angle sideways and frontal.

Thank you

Two more elevations, this being first

Last one

You'll consider applying a mesh to cover the key points.

A mesh can be converted to roof segments by downloading a 'Goodie' called "Mesh to Roof" See the Help menu for a link to the website for downloading.

Or if the slope, see screen shot is a steady angle you can adjust the pivot line of the roof.

I believe the roof contains several lines that are not coplanar ... so in this case, I would go with Dwight's method (or maybe trying to achieve it directly with several segments of roofs).

I don't have the specific cross-sections through your building to check this against, but this should be easy to tackle with OBJECTiVE. Also, when you say roof profile, do you mean the profile of the roof structure or the cladding applied to it? I've drawn an example with OBJECTiVE with a custom profile bent through the approximate shape of your roof. The object has a vertical offset for the overall rise, is bent to the curve of the perimeter walls, is twisted along its length to echo the changing pitch along the length, and the top spine is also bent to bring the tangent to the curve level at the roof apex. The whole object is then split down the middle and mirrored (see attached plan, elevations, and 3D). I can give you specific parameters if you need more detail.

Wow that looks exactly like what I'm looking for. If you could please give me the parameters and just an easy instructions I would greatly appreciate it.

Because I've been playing around with the OBJECTIVE tool the whole day yesterday.. I just want it to go on top nicely over the steel posts. I would even attach the archicad file once I have access to it as I'm at work.

Though thank you would greatly appreciate how you did that.

I can't seem to upload the .zip file, though would greatly appreciate the parameters, like I'm trying to do what you stated, though it's no where close to as what your image has shown.

I just need those parameters and which parameters need to be changed in-order for me to have it on the posts.

I'm trying to reply, but the forum engine seems to have gone mad and won't take any images - I'll try again tomorrow.

OK - trying again. Referring to the attached image, I did the following:

1. Draw a cross-section through the roof and create a new section profile object with OBJECTiVE > Component > New Profile;

2. Place an instance of the new object from the roof end to the centre;

3. Use OBJECTiVE > Tools > Bend to bend the profile to the curvature of the exterior walls

4. Elevate the end of the profile (either using the Y Offset in the object settings, or opening a side elevation and using OBJECTiVE > Tools > Offset to loft it;

5. Enter twisting angles in the objects settings to achieve the required roof pitch at the start and end of the roof;

6. A side elevation of the roof should look like this;

7. Use OBJECTiVE > Tools > Bend to curve the roof in elevation (as required);

8. Use OBJECTiVE > Tools > Split (in elevation) to cut the roof end to a vertical line;

9. Use OBJECTiVE > Tools > Split (in plan) to cut the roof to the ridge line;

10. Mirror a copy of the roof to the other side;

11. The finished result in 3D.

Hope this helps.

OBJECTIVE is KING!

Yes, gotta agree. Objective does it again. It seems to be able to solve so many sticky problems in such a graceful way, how can it not be included by default with ArchiCAD?

Ralph: I suggest that you buy the sole rights to the ArchiCAD code and incorporate it natively into Objective.

Thank you so much!

I'll be sure to do the steps you've provided, hopefully it all turns out as good as the images you've attached.

Jamie.
