Darin K Posted July 8, 2023 Share Posted July 8, 2023 I'm drawing a black-box theatre and am including a class for the HVAC (as it interrupts our grid and is a crucial piece of information for lighting designers). I drew the ducting as an extruded rectangle which I then turned into a symbol (so I could set the Z height). Is there a way for me to give the HVAC symbols a hatch pattern when viewed in 2D (Top/Plan) view? Quote Link to comment

ITEMS) and set fill to your preferred hatch Quote Link to comment

I don't know what settings to check to bring it back Quote Link to comment
Darin K Posted July 8, 2023 Author Share Posted July 8, 2023 Okay, I figured out how to make it visible, but when I go to 2D Appearance (in the OIP), select "Use 2D Class Attributes", and then set the Class Fill to a hatch, it still doesn't show as hatched on the Top/Plan view Quote Link to comment
Pat Stanford Posted July 8, 2023 Share Posted July 8, 2023 Is that Class set to Visible? Quote Link to comment

Tom W. Posted July 9, 2023 Share Posted July 9, 2023 I would use a Hybrid Symbol rather than an Auto Hybrid. This was the other option that @mjm gave. You will have a lot more control over the 2D representation, both Top/Plan + other views. If you want, you can include different geometry in different classes + show different things at different times e.g. a schematic representation, a realistic representation, text, etc. 3 Quote Link to comment
Darin K Posted July 9, 2023 Author Share Posted July 9, 2023 Is there a simple way to undo the auto-hybrid function of this symbol, or should I just redraw it? It's pretty simple geometry Quote Link to comment
Tom W. Posted July 9, 2023 Share Posted July 9, 2023 If you Ungroup the Auto-Hybrid in a 3D view it will return to being a 3D symbol. Then right-click on it + chose 'Edit 2D Components' to add Top/Plan geometry. In the Top view edit mode you can right-click + choose 'Generate 2D From 3D Component...' 4 Quote Link to comment
Darin K Posted July 9, 2023 Author Share Posted July 9, 2023 While we're on the subject, I feel like simply drawing and placing this object is taking too many steps. I am using an extruded rectangle to represent an HVAC duct. I draw the 2D shape I extrude it I make it into a symbol (because you can't set the Z height on an extruded object) Place the symbol Make it a hybrid symbol Is this correct? Quote Link to comment
Tom W. Posted July 9, 2023 Share Posted July 9, 2023 Sounds good to me. Or you can draw the 2D shape, copy it, extrude it, paste in place, select extrude + 2D shape + create symbol: with both a 3D object + 2D object selected a Hybrid symbol will be created in one action. Quote Link to comment

That would require extruding it on the same plane as you want the 2D shape, yeah? Quote Link to comment
Darin K Posted July 10, 2023 Author Share Posted July 10, 2023 (edited) I did an experiment in a blank document. Drew a rectangle, copied it, extruded it, pasted the 2D on top, created a symbol, added hatch. It's now doing the opposite of what I want; it's displaying the hatch in 3D views, but nothing in Top/Plan EDIT: This is what happened when I made it a hybrid symbol. Before I did that, it was showing hatch in both 2D and 3D views. I only want the hatch to display in Top/Plan view. Edited July 10, 2023 by Darin K Quote Link to comment
Tom W. Posted July 10, 2023 Share Posted July 10, 2023 Does it say '2D/3D Symbol' in the OIP or '3D Symbol'? Sounds like the latter to me. The rectangle needs to be at Z=0 when you create the symbol not raised to the top of the extrude. Then a 2D/3D (hybrid) symbol will be created Quote Link to comment

Tom W. Posted July 10, 2023 Share Posted July 10, 2023 Not sure what you've done. You need the 3D object + the 2D object selected at the same time then run 'Create Symbol'. It should create a 2D/3D Symbol if the 2D object is at Z=0. Post the file if you like Quote Link to comment

Darin K Posted July 10, 2023 Author Share Posted July 10, 2023 In case it's not obvious, I'm trying to learn VW purely through VW University tutorials (which are great, but it's like drinking out of a firehose). Quote Link to comment
Darin K Posted July 10, 2023 Author Share Posted July 10, 2023 I figured it out! I have to make the extrude a 3D symbol first, then draw the 2D (with hatch) over the top, select both, and make them a symbol again Quote Link to comment

I just selected both objects then went to Modify > Create Symbol... + it gives me a 2D/3D Symbol. You see the 2D geometry in Top/Plan view + the 3D geometry in 3D views.

Hatch Issue File_TW.vwx I see. It seems to be working now (though it gives me the circle/cross symbol that I have to click into the document before it converts). Thank you for your help, I can finally move forward Quote Link to comment

When you create a symbol you have two options for setting the insertion point: 'Next mouse click' allows you to place it precisely where you want + this is the option you used. '3D Object Centre' (or 'Plan projection centre' if you are in a Top/Plan view) does it automatically + places it in the centre of the object. Just to explain what the circle/cross symbol was! 1 Quote Link to comment
