Parametric Block

dels@bbo.co.nz

I am using the "Fix" constrain under the Parametric menu to constrain the insert point and grip. Once I insert the block in my dwg, the fixpoint has moved and is not relative to where I selected. I am new to parametric blocks and struggling to find documentation to help me salve this.

GCFIX is used to fix an entity or point on an entity in it's current location. Attach an example where it's been used.

There is quite a bit to parametric blocks. this video gives an introduction to some of the possibilities in V22

I am on a much older version, so don't have parametric blocks. However, I think you are misusing "Fix". That constraint forces a point or object to stay put and not move. You can fix multiple objects on a parametric drawing.

When making a block, you can use the "BASE" command to tell BricsCAD what point to use when you are inserting that drawing into another drawing as a block. If no base point is set, it uses the origin of the world coordinate system as the base. I think Base is the command you actually want to use.

Thanks, Guys.
I have misunderstood the function of FIX. Joe, I used the base option and worked, thx for that. Are there any tutorials that could take me through all the elements of Parametric blocks? Jason, your video helps a lot, but there are things like "Designtabels" if I compare it to AutoCAD, I can not have a column with duplicated description.

e.g. I have two suppliers for the same items. The items are made of different sizes, which differ between the two suppliers. I want to select the supplier and then the relative sized item.

Again, note that I don't have a new enough version to know for sure.

But, I did find this regarding parametric blocks;
BricsCAD features the Suppress tool. This feature was added in BricsCAD V20 and allows you to hide any object within a block. Suppressions can be treated like parameters and can be driven by a design table. This is where the design table really shines: you can embed several blocks into a single block definition and assign specifications to your suppressions. If done correctly, selecting a specification from the design table should display only the objects that correspond to that specification, and suppress all others.
