If the layer exists, then it will run our program. If it doesn’t exist, then it will give a warning. Now AutoCAD will try to find the layer first before executing our command. else - and give warning if it doesn't exist (command "_TEXT" textloc "" "" textcontent) (setq flag (tblsearch "LAYER" "A-Anno")) looking for A-Anno layer So we need to add (progn GROUP OF STATEMENTS) to run several statements. The problem is IF only allows you to run one statement. We have discussed about using conditional IF in AutoLISP before. We need to check if the layer exist or not first. error: AutoCAD variable setting rejected: “clayer” “layername” What if the layer doesn’t exist? AutoCAD returns error warning. (setvar "CLAYER" oldlayer) restore active layer (command "_TEXT" textloc "" "" textcontent) create the text (setvar "CLAYER" "A-Anno") change layer to annotation layer (setq oldlayer (getvar "CLAYER")) get current layer

This is the code after we put it all together:

Set the current layer to previous layer.

You may want to consider ask for height and rotation angle. In this sample we ask for text content and position.

We ask for required data for creating text.

Set current layer to a different layer.

Get current layer and save it to a variable.

We want to create a LISP program to create text, and use a default layer. (setvar "CLAYER" "LAYERNAME") Sample: creating text Current layer variable is controlled by CLAYER. We can change the current layer using setvar. If you’re not familiar with layer standard, CADD manager has a short article about the concept. Layers are the most important thing to manage our drawings. Let’s explore the possibility to use it to control our drawing standard.

Now let’s see how to control the other properties you need to control: layers and styles. This will ensure the users (or you) to use the same block for every drawing. In system variable and COND conditional, we discussed how we can use block to create grids. It’s not just about speed up the drawing creation, but also to maintain our standard. We can create simple LISP program and get many benefits from it. ANI-MATE - this is a sweet little animation routine, it's been around for a decade now and looks suspiciously similar to the one introduced in Acad2007.An AutoLISP program doesn’t have to be difficult. AUTO MATERIAL ASSIGNMENT - this one allows me to select a pre-dined material (concrete, asphalt etc) from a drop-down list box and then apply these by object, layer or by a bounding polyline.ġ0. BATCH LISP PROCESSING - this little app will allow me to run any lisp routine on a whole folder of drawings, including sub-folders if desired.ħ. REVERSE OBJECT - Does what it says on the tin.Ħ. I use this to remove excessive polyline vertices and to convert arcs, circles & ellipses to polylines.ĥ. RESAMPLE OBJECT - this routine effectively traces over existing objects using a user-defined number of vertices. TERRAIN MODELLING - this is a combination of numerous 3D ground modelling routines such as TIN creation, breaklines, surface drapes & burrying etc.Ĥ.

This one doesn't sound very interesting but it saves many hours of tedious manual editting.ģ. MAP CONVERSION - this one automatically reconstructs missing symbology in digital map data imported from a proprietry GIS system. This little baby can generate a dozen A1 drawings within a minute.Ģ.

Basically I draw a pipe route on a digital map using a polyline, select it and voila, a series of drawings each showing a plan (aligned to the pipe-route) and a corresponding long section beneath. MULTI-SECTION - a terrain & pipework longsection generator. An interesting thread Big G, after careful consideration my top 10 ranked according to time savings would be:ġ.
