Wood Cad Cam outline geometry constraint options needing elaboration3/30
What is the implication of using a relative or absolute coordinate? A linear division, length and angle, endpoint, etc? Here's what I'm trying to do at this moment, and perhaps someone can illustrate what settings need to be employed to accomplish it: I am designing an L shaped upper corner cabinet which must be able to grow and shrink parametrically, both in overall dimensions, and also the depth of the left and right sides. By default, the cabinet would be 60X60cm with a depth of 30cm. But sometimes it may be 65X90, and 25 deep on the 65 wall and 38 deep on the 90 wall. The adjustable shelves must stretch accordingly, and maintain a consisent offset of 1cm from the front face of the L shape. (The front, back, left, right offsets used for regular shelves don't work for L shaped cabinets.). Here's an example of what happens when I stretch a badly defined adjustable shelf:
We have been able to do this type of shape inserting a variable for depth on each side. To use a variable on the geometry you need set it as an absolute value.
Sorry, I realized I should have been more specific.
Dan, that was one awesome answer!
Glad to assist.
Got it. Thanks again.
I'm speaking to comments not addressed to me as well as ones that were because I'm learning too.
We have been experimenting with different start points trying to get the editor to find the "front". I don't know if you have the same problem we do but the more complex the shape the more careful you have to be with connections, doors and edging because even though we have placed a door on a 'side', wcc sees the part as a side and tries to connect it. I'll find a door hinged with a screw in it once in a while.
Variables will be carried with the job once your order value has been changed and saved. Set the default as normal and change an order value for the custom. Order values will not be carried to another job, even if they are opened at the same time, each job will keep its' own.
I haven't tried it but surmised that a variable can only have one value in any job.
On the zone reveals:
Ditto to your issues Dan.
I just tested that with the following results:
"Problem is, I don't see the option to use a variable for a PD within the construction principle, nor a variable for outline geometry"
I have to say I don't think i'm understanding the question fully either but (as long as the upload works) I've attached an example of variable geometry. Not necessarily a good one but....
Your cabinet is complex and so will be the solution but If you draw the geometry for each part with variable based formulas, it can work.
"Problem is, I don't see the option to use a variable for a PD within the construction principle, nor a variable for outline geometry. "
Hopefully I understood your question.
After reading Russell's response and re-reading I may be catching on.
He dealt with how to pick up the part definition as a variable.
Your conclusions seem logical.
"nor a variable for outline geometry"
The part definition is pretty much (I'll use the term) a primary element. If you change its' geometric base you would most likely have to change other elements like edges, machining and so on, meaning you need a new part definition that you can pick up with a variable.
I would make my final comments here, hope you take it as advise and not as critique.
1, When building a library of your own products concentrate on having what you really need as opposed to "what IF I want" scenario. Meaning setup your Stadium shelves only if you really sell that type of product.
2, If you really need to have different shape of your shelves in the L type article then you could use Multipart PD as your Primary PD referenced in your CP, and the Multipart would use the Variable PD linking to PDs with their own shapes. In the Article designer You will NOT check the box "Outline Geometry from Part Definition". This was the old approach before that check box even existed. The advantage here is that MPE (Multipart PD) will be "consumed" for the shape of available space in Article and child PD will keep its shape within the overall size of MPE. It gives you the flexibility of rotating edges if needed.
3, Regarding Variables. These are the most powerful elements of the software IMHO. Use them but be in control. For numeric variables make sure you are using the shortest name possible and you add a comment to each numeric variable i.e. a variable $TKH has a comment "Toe Kick Height". the reason for this is that when you use linear divisions the dialog is limited in length you can type.
4, Outline Geometry: As mentioned by others there is no Variable for, as it would not make any sense. Just try to apply a geometry of your L shape to any existing box article you have. It's not pretty. Saying this the Outline geometry used in part definitions is used for same part definition with and without the toe-kick for example, so once you see it as 4 edges part other times as 6 edges part. (PD has always 6 edges but using Numeric Variables some edges are = 0 mm). This approach gives you control over applying same Profile to each edge.
And as a last off topic comment I am interested to hear from any IMOS/WCC user looking for a job willing to relocate to NC just reply to my name. (I hope I am not breaking any rules here)
Hope it helps.
I for one am very grateful indeed for all this advice!
Hi, me again! I been using the tips in this forum with really good results.
I'm not certain about question 1 but your example shown takes us back to the "hitch" post.
The "filter on a variable" answers question 3 perfectly. Thanks!
Some times at least I think I'm amusing.
Not sure which version you have but your column display of article based variables doesn't come up on mine (11). We can make article specific modifications and these can be applied globally to that article if saved but that seems to me maybe a bit tedious for your purpose.
I re-read a few of the earlier posts. I think the point to the variables warning was as much about keeping the name short as not using more than one. I personally find it easier to keep track of a more descriptive name for some things but do try to limit the ones going into formulae.
Back to your # 4, the construction rule can be changed during the job and (somebody may correct me here) should not have any effect other than changing the defaults that populate the various part positions as you create an article going forward. I don't think you'll access that ability from within the article designer but before you start it, save as, change your default, ok.
...the missing column only appears if you click on article related variables and then the article. I'm also using V11.0
I had been out for a few days but thanks for that. I must have missed that day in school.
Hi again all.
