Copy block to multiple selection of objects

Anonymous — Fri, 09 Nov 2018 15:14:08 GMT

My procedure is this:
1. I extract a set of 3D points from the Photoscan software, which then have X, Y and Z coordinates;
2. amount of this dxf in Autocad;
3. I create a block (for example a circle with a cross) with a center in one of these points and then placed in space;
4. I attribute the position attribute to this block by selecting only the Z coordinate and assigning the label "QUOTA" to it;
5. manually copy this block on the model at each point (see step 1);
6. through Express Tools explode the attribute;
7. use the FLATTEN command to fade all points and attributes to zero.
8. at this point I have the set of points in 2D (all at altitude 0) with however indicated next to each of its previous altitude Z (altimetric);
My need is to have an automatic procedure that replaces and accelerates step 5 where instead I spend a lot of time copying the block on every point if these are obviously numerous.
In practice my idea is to have a command that allows me to copy the selected block (to which the position attribute is connected, for example) to a multiple selection of identical or similar objects, in my case all the objects in the drawing point or even better all the point objects that are on a specific layer.
Who can help me?

Thank's a lot.

There are a few Autolisp placing a block at a node. That's what you need.

Where I can find these Autolisp?

What is the procedure?

I don't know how write o program these type of Autolisp.

Download the .lsp and then in autocad you do a appload command, follow the instruction on this link.

I tried the LISP and it works well.
Replaces the selected points with a block as desired.
The problem, however, is that if I in the block define an attribute (for example in my case the position Z) when the LISP performs the replacement I no longer see the label of the Z position that was defined in the attribute of the block.

This procedure replaces the point with a block.
Instead, I would like the block to be copied on all points.

Google for that type of routine, the one you used had instruction to it, there are many to do what you need.

Thank you very much.
