Hi, everybody :)

I would like to know how you edit symbols or CAD blocks.

I don’t have much experience creating my own objects so I usually download them from pages like 3D Warehouse.:rolleyes:

Most of the times I need to make changes or remove elements included in these objects so I just load the symbol, go to Edit CAD block and try to modify what I need in the CAD Block window.

When the object is ready, I just add it to the library, but when I try to reload again the symbol previously created I can’t see it in the 3D view.:unsure:

I’m sure I’m missing some steps or, probably, I can’t understand how symbols work.

Many thanks for the help! :)

3D Symbols can only be edited within the Symbol dbx (little chair) and the things you can do there are limited.  

You can use the "Delete Surface Tool" in a 3D Perspective View (nothing else in the plan) to get rid of some things you don't want.  But then you need to create a new Symbol from what you modified.

 

Symbols are not the same as the CAD Block.  That's just the plan view representation of the 3D Symbol.  You can modify the CAD Block but you need to assign the modified CAD Block to the Symbol.  It's then still the Symbol that you need to place in the model, not the 2D CAD Block which wiil be placed in the model along with the Symbol.

 

Study the Symbol dbx - and the "Create Symbol" tool in Chief to learn the ins and outs of Symbols.  I don't know if there are any good videos but you might try looking for them on Chief's Website.

That's not a very easy question to answer because making your own symbols can either be very easy or very hard depending on what type of symbol you are trying to build.  

 

In simplest terms, a symbol is just a collection of 3D surfaces that will show in a camera view, a collection of 2D cad that will display in a plan view, and some other settings that help control how it works in Chief.

 

The 2D cad may or may not represent the 3D surfaces.  Think about an electrical switch.  What you see in plan view has very little to do with what the 3D surfaces look like in a camera view.  So editing the cad block for a symbol, or replacing it with a different cad block, won't really have any affect on what it looks like in a camera view.

 

To build your own symbols with the 3D surfaces you want, you can use any tool or combination of tools in Chief that creates 3D surfaces.  Poly solids, moldings, and other shapes can be very helpful.  One of my favorite tools that a lot of people don't think about is cabinets.  Cabinets can really be considered a building block tool and many things can be created using cabinet components as a starting point.

 

Here is a tech article that has some good general info (and it includes links to some other related articles):

https://www.chiefarchitect.com/support/article/KB-00761/modeling-custom-3d-objects.html

 

There is also a lot of good info on the symbols forum (which is also a good place to go for how to and free stuff):

https://chieftalk.chiefarchitect.com/forum/9-symbols-and-content/

 

Be careful though because trying to design the perfect symbol can really be a massive time sink.  Don't underestimate how valuable an existing symbol that is "close enough" really is.

3D Warehouse Symbols are best edited in SketchUp, ( or other software that can open .skp files), many come with "extras" you don't want or need , but editing the Chief CAD Block does not remove those Items unfortunately.

 

Some Homework :)

Not sure but Eric may have a Video on  using the Surface Delete Tool ?       Eric ? @solver

Hi, Joe!:) I have managed to use the "Delete Surface Tool" and it worked for what I wanted to do (just delete).:rolleyes: I didn't know what this tool was for. The create new Symbol worked aswel so I guess I have something done in my list of learnings.:D

Hi, DBCooper! :) The tool I use more is the polyline square or box, or just the triangle shape. What I can do for the moment is reall simple: some moldings or figures to fill spaces; not much. I can't think about makind a perfect symbol. It's impossible for the moment!:unsure: I try to use symbols from the library, change textures and so on.

Hi, Mick!:lol: It would be really welcome! I'm working with the basic knowledge now. :rolleyes:

 

* By the way: Very interesting the use of the soffit. I'll make some tries in the future :D

@marlem2000For symbols that are downloaded from 3d Warehouse and then need to be edited, it can be helpful to edit them in Sketchup and then save, download and import that new edited version of the symbol.

Which means you'll need to subscribe to Sketchup, with the Pro version going for $299 per year.  Might be worth it if you are going to use 3D Warehouse symbols at the rate of two or three a month.

 

I have the free version Sketchup Make 2017, which is desktop, and no longer available.  None of what I can download from the 3D Warehouse will open with my 2017, but I can scratch-build all I want, and am proficient enough with it to make furniture and fixtures.

In my case, it is not worth since I don't work professionally with Chief Architect. I just make my own designs as a way to relax.:unsure:

Or one could simply use the free online version.

I think that's the best option for me. I'm not planning to build anything serious with symbols; just replacing some textures or remove some elements that I don't need.:)

      My preferred method for placing freestanding refrigerators in a tall cabinet is to create a cabinet with an opening and manually place a refrigerator in that opening. This works great for me because I can place the refrigerator however I want in the cabinet. I often leave some space at the back as an allowance for the electrical and water lines. 
       
      The issue I am having is that the refrigerator symbol I place in the cabinet shows up on top of the cabinet symbol. I want the cabinet to show that the refrigerator has been placed inside of it. I don't really know if there's a way to edit the order of how symbols display, if there is how do I accomplish that? If there is not and you have the same issue, what do you do to fix it? I attached a photo to show how my refrigerators are displaying in relation to tall cabinets.

      Hi all, Just wondering if anyone could help with some issues Im having with importing 3d symbols - I am trying to import some SKP files into chief (decor, people etc) and while some are coming in fine others are coming in with no texture/materials or the materials are not applied correctly (eg a symbol of a person the texture is placed wrong) - if someone could help me out with how to "lock" the material that would be super helpful. Thanks 
       
      first image is how it appears in sketchup and second how it imports into CA

      Hey everyone, I was wondering if someone would be able to convert some 3D symbols I have into something I can import into chief. 
      I need some specific symbols for a design I am doing and an unable to figure out how to convert them (including their textures) into one of the formats chief will allow to be imported as a symbol. I have tried pulling the obj and fbx files into sketchup but they are missing the textures and these are quite complicated collections, too many textures to add back in one at at time. I only have a basic knowledge of sketchup and have a mac computer which doesn't support 3ds max (the only program i have come across to do this). 
      Any help would be greatly appreciated.  
      They are big files so i can zip and email them if someone is willing to help. 
       
      Thanks, 
      Emily
